Computed tomography (CT) in the diagnosis of intracranial abscesses. Brain abscess, subdural empyema, and epidural empyema.

Nine cases of brain abscess, five of subdural empyema, and one of epidural empyema with associated subdural empyema were identified using computed tomography (CT). Smal and multiple abscesses as well as unilateral, bilateral, and parafalcine empyemas were detected. These lesions were demonstrated rapidly and accurately, even in areas that are demonstrated poorly by other diagnostic techniques. No false-negative studies were found in cases of brain abscess or subdural empyema. However, since the appearance of brain abscesses of CT scans is similar to that of neoplastic and vascular lesions, false-positive reports of brain abscess were encountered.

Percutaneous drainage of hepatic abscesses: comparison of results in abscesses with and without intrahepatic biliary communication.

Results of percutaneous drainage performed in eight patients with eight liver abscesses with intrahepatic biliary communication and 22 patients with 26 liver abscesses without biliary communication were analyzed to determine whether the presence of an intrahepatic biliary communication affected the outcome of treatment. The clinical features and response to treatment of both groups were compared. The presence or absence of biliary communication was determined by injection of contrast material into the abscess under fluoroscopic guidance either during or several days after initial drainage. Duration of drainage was longer (p less than .05) in patients with communication (range, 7-44 days; mean, 22 days) than in patients without communication (range, 1-33 days; mean, 13 days). Percutaneous drainage was curative in five (63%) and palliative or temporizing in one (13%) of eight patients with communication. It was curative in 15 (68%) and palliative or temporizing in five (23%) of 22 patients without communication (p = .317). Liver abscesses with intrahepatic biliary communication did not require percutaneous transhepatic biliary diversion for cure. Despite longer duration of drainage for abscesses with intrahepatic biliary communication, the cure rates of percutaneous drainage for both groups were similar. Patients in whom an intrahepatic biliary communication was shown did not require alternative interventional or surgical measures for cure.

[Aspiration and drainage for a gas-producing brain abscess causing delayed bleeding from the abscess capsule--a case report].

A 65-year-old man was admitted with the complaint of gait disturbance. CT scan revealed a low density lesion in the right parietal lobe. MRI was carried out 3 days after admission, the lesion showing low intensity on T1 WI and T2 WI. Gd-DTPA enhanced T1 WI showing abnormal enhancement surround it. CT scan then revealed a gas bubble in the lesion 12 days after admission, so we diagnosed it as gas-producing brain abscess and aspiration, drainage and irrigation with antibiotics were performed. Although, the brain abscess was reduced in size after the operation, the lesion expanded again 2 weeks after the operation. MRI was performed and the lesion showed iso-intensity on T1 WI and high intensity on T2 WI. Emergent aspiration and drainage were performed and uncoagulated old-hematoma-like matter such as chronic subdural hematoma was removed. As significant neovascularization with inflammatory cells had been detected in the capsule of the brain abscess, we suspected that aspiration and drainage surgery for brain abscess may cause delayed bleeding from the capsule of the abscess. We conclude that attention should be drawn to such a complication.

[Abscess excision and primary fistulectomy as initial therapy of peri-proctal abscess. A prospective analysis of 122 patients].

A prospective study of 122 patients with anorectal abscesses was carried out to elucidate the value of abscess drainage with primary fistulectomy, when fistulas were identified. Patients were followed from 2 1/2 to 3 1/2 years with a mean follow-up of three years. In 52 patients (Group A) a primary fistula was present (42.6%), in 47 patients simultaneous excision of abscess and drainage of the intersphincteric space combined with partial sphincterotomy was performed. Recidives occurred in 17.3%. In 5 patients with a high transsphincteric or suprasphincteric fistula, a two-stage fistulectomy was done. In all 70 patients of group B no fistula was found at drainage operation. The incidence of recurrent anorectal abscess was 21.4%. In this group it is shown that the rate of recurrence was not related to a simultaneous excision of abscess and drainage of the intersphincteric space.

[Aspiration and drainage for brain abscess causing massive bleeding from abscess capsule: case report].

The authors report a rare complication during aspiration of a brain abscess. A 23 year-old man who had undergone surgery for empyema two months previously presented himself at our hospital complaining of headache, deterioration of activity and conscious level. An emergency computed tomography demonstrated a left frontal brain abscess. Aspiration and drainage were performed. However, this resulted in massive hematoma in and around the abscess capsule. Following craniotomy and excision of the abscess, the patient was cured. Microscopic examination of the abscess revealed the formation of a complete capsule consisting of fibroblasts and collagen fiber. In addition to this, significant neovascularization with inflammatory cells was apparent around the capsule. These findings suggest that profuse hemorrhage may occur in aspiration and drainage surgery.

[Parapharyngeal abscess secondary to peritonsillar abscess in childhood].

We report a case of parapharyngeal abscess in a five-years-old girl, secondary to a local extension of a peritonsillar abscess. The typical signs of peritonsillar abscess, medially displaced tonsil and displacement of the uvula toward the opposite side, were either less pronounced than usual. In this case, with parapharyngeal involvement, the treatment was abscess tonsillectomy under intravenous anti-.

Psoas abscess associated with iliac vein thrombosis and piriformis and gluteal abscesses.

BACKGROUND: A 14-year-old boy was admitted because of lumbago and high fever. METHODS/RESULTS: Computed tomography scans revealed psoas, piriformis and gluteal abscesses as well as right iliac vein thrombus. A right femoral venogram demonstrated compression from the psoas abscess and thrombosis of the common iliac vein. Appropriate surgical drainage, administration of antibiotics and anticoagulant therapy were effective in the present case. CONCLUSIONS: This is the first report of primary psoas abscess associated with vein thrombosis and is also unique in that abscesses were multiple without predisposing diseases or trauma.

ABSCESS-FORMING FACTOR(S) PRODUCED BY STAPHYLOCOCCUS AUREUS. II. ABSCESS FORMATION AND IMMUNITY BY A STAPHYLOCOCCUS AND ITS MUTANTS.

Lam, Gow T. (Jefferson Medical College, Philadelphia, Pa.), Francis J. Sweeney, Jr., Charlotte M. Witmer, and Robert I. Wise. Abscess-forming factor(s) produced by Staphylococcus aureus. II. Abscess formation and immunity by a Staphylococcus and its mutants. J. Bacteriol. 86:87-91. 1963.-Three mutants were derived from a virulent parent strain of Staphylococcus aureus by ultraviolet irradiation. One mutant retained coagulase but lost its hemolytic activity; a second had no coagulase but retained its hemolysin; and a third contained hemolysin and bound coagulase but no free coagulase. The parent strain was coagulase-positive, hemolysin-positive, and possessed all the known extracellular products. All four strains were compared by bacteriophage typing, mannitol utilization, and antibiotic sensitivity tests. The four isolates were studied for their pathogenicity in Swiss albino mice and four strains of inbred mice. Their immunological characteristics as studied by repeated subcutaneous injections are reported. The importance of hemolysin and the coagulase in abscess formation is discussed. Local immunity was produced only by the parent strain, but abscesses were produced by all the strains containing coagulase.

[Iliopsoas abscess accompanied by epidural abscess--a case report].

A 55-year-old man was admitted to a hospital with pain of the low back as well as the left leg, and fever. He was suspected of suffering from the lumbar disc herniation because of the presence of Lasegue's sign on the first physical examination. Abdominal computed tomography, however, revealed the swelling of the left iliopsoas muscle. Iliopsoas abscess accompanied epidural abscess was confirmed by subsequent magnetic resonance imaging (MRI). Antibiotic therapy was started for the successive 8 days. The fever resolved, but the pain persisted. The abscess extending from the iliopsoas muscle to the epidural space was still seen on the MRI 20 days after the completion of the antibiotic therapy, and he still complained of the pain of his low back and left leg. Therefore, we conducted epidural puncture under fluoroscopic guidance. Approximately 3 ml of pus was aspirated from the epidural space. Then, his complains decreased remarkably. Iliopsoas abscess should be taken into account in case of a patient with pain on the low back and leg and also inflammatory signs such as fever and leucocytosis.

Successful treatment of a large choroidal abscess in an immunocompetent child. Treatment of a choroidal abscess.

BACKGROUND: We report the case of a systemically well 4-year-old Aboriginal boy who developed a choroidal abscess after being poked in the left eye with a blunt object. CASE REPORT: This boy presented with redness and reduced vision in the left eye after a blunt object was poked into his eye by his sibling. He was noted to have a choroidal mass which finally manifested as a choroidal abscess. RESULTS: His initial visual acuity was 6/60, and dilated fundus examination demonstrated a localised solid-appearing choroidal elevation involving the posterior pole, including the macula. An ultrasound of the eye revealed a choroidal haematoma with an atypical appearance, whose height was 8 mm with a base of 12 mm x 10 mm. The lesion failed to resolve, and eventually resulted in orbital cellulitis that did not respond to intravenous and topical antibiotic treatment. He then went on to achieve complete visual recovery after successful management by transcleral incision, drainage and systemic antibiotic therapy. CONCLUSION: Choroidal abscess has been described in patients who are debilitated, immunocompromised or suffer with systemic disease such as cystic fibrosis or endocarditis. This case represents a unique report of staphylococcal choroidal abscess in a healthy child that completely resolved after transcleral drainage and systemic antibiotics.

Peritonsillar abscess--critical analysis of abscess tonsillectomy.

The risk of secondary haemorrhage following abscess tonsillectomy is reported in the literature with differing rates. A retro- and prospective analysis of complication rates following abscess tonsillectomy was conducted in 142 patients (54 females, 88 males; mean age: 35 years). In 22% of patients, a secondary haemorrhage occurred. In half of these (11% of total), the haemorrhage had to be treated surgically. Secondary haemorrhage occurred most commonly on the 6th and 8th postoperative days. Reports in the literature are not in unison about the risk of secondary haemorrhage following abscess tonsillectomy and therefore allow no final judgement about an objective risk of this complication. This report strengthens the results of the 'Comparative Audit Service' analysis from 1997, which did show a high risk of secondary haemorrhage following tonsillectomy, as well as following abscess tonsillectomy.

Thyroid abscess due to Acinetobacter calcoaceticus: case report and review of the causes of and current management strategies for thyroid abscesses.

Thyroid abscess was a common condition in the era before antibiotics. In the current medical environment, however, it is a clinical entity that is seldom encountered. We report the case of a unique cause of thyroid abscess, the environmental Gram-negative bacterium Acinetobacter calcoaceticus. Review of the published causes of thyroid abscess since 1980 demonstrated that although Gram-positive bacteria (Staphylococcus and Streptococcus species) remain the most common causes, there has been a marked decrease in the number of cases caused by mycobacteria, Salmonella species, and anaerobes when compared with the early part of the 20th century. Patients infected with the human immunodeficiency virus, however, still develop mycobacterial and fungal thyroid infections with some regularity. Reported modes of management of thyroid abscess vary, but drainage remains an integral component of therapy for resolution of the infection.

Tuberculous abscess of the abdominal wall and multiple splenic abscesses in an immunocompetent patient.

We report a case of a 39-year-old human immunodeficiency virus (HIV)--negative male who presented with a progressively increasing swelling in the left hypochondrium. He did not manifest fever or toxaemic symptoms. Computerised tomographic scan (CT scan) of the abdomen revealed an abscess in the anterior wall and multiple splenic abscesses. Fine needle aspiration from the abscesses in the anterior abdominal wall and the spleen confirmed the diagnosis of tuberculosis as the aetiology. The patient responded well to antituberculosis treatment and the abscesses regressed considerably.

Pseudallescheria boydii brain abscess: association with near-drowning and efficacy of high-dose, prolonged miconazole therapy in patients with multiple abscesses.

Brain abscess caused by Pseudallescheria boydii is a highly lethal infection, usually seen in immunosuppressed patients. Five patients with P. boydii brain abscesses are described. Four of these patients acquired their infection after near-drowning; 1 patient developed an abscess after penetrating head trauma. Two patients survived their infections, which included involvement of other body sites (lung, eye, bone) as well as multiple undrained brain abscesses, after prolonged courses of high-dose parenteral miconazole (80-90 mg/kg/d). Progressive increases in miconazole dosage during the treatment periods were required to produce serum levels above the minimum inhibitory concentrations of the fungal isolates.

[Brain abscess (Part 5)--Brain abscess following internal carotid occlusion (author's transl)].

Three cases of brain abscess following an occlusion of the internal carotid artery were reported. Case 1: A 6-year-old girl with congenital heart disease was admitted with headache, disturbance of consciousness and left hemiparesis. Right carotid angiography revealed an occlusion of the right internal carotid artery. After 6 months, she was readmitted with high fever. CT scan revealed a low density area and a ring-like shadow at the same site of cerebral infarction. Case 2: A 69-year-old man was admitted in semicoma and with right hemiplegia. Left angiography revealed an occlusion of the left internal carotid artery. After 2 months, a brain abscess was noted in the infarcted area. Case 3: A 20-year-old man with congenital heart disease, was admitted due to headache, vomiting and high fever. CT scan revealed a brain abscess in the right frontal lobe. Carotid angiography showed bilateral internal carotid artery occlusion. We concluded that diminution of cerebral oxygen and encephalomalacia are predisposing factors to the evolution of brain abscess.

[A case of Klebsiella pneumoniae infection causing a buccal abscess complicated with multiple lung abscesses].

A 51 year-old man fitted with a dental prosthesis was hospitalized with buccal swelling, fever and chest pain. Laboratory data showed marked inflammatory changes, and chest radiography and CT scanning revealed small nodular shadows within the lung. A diagnosis of multiple lung abscesses secondary to a buccal abscess possibly caused by the prosthesis was made from needle aspiration biopsies of the lung nodules and of a buccal lesion. Klebsiella pneumoniae was isolated from these lesions and from a blood culture. The patient was successfully treated with antibiotics and by surgical drainage of the buccal abscess. It is important to note that the patient was immunodeficient at the time as a result of diabetes and alcohol intoxication.

THE FREQUENCY OF LYMPHOGRANULOMA VENEREUM IN PERSONS WITH PERIRECTAL ABSCESSES, FISTULAE IN ANO, OR BOTH. WITH PARTICULAR REFERENCE TO THE RELATIONSHIP BETWEEN PERIRECTAL ABSCESSES OF LYMPHOGRANULOMA ORIGIN IN THE MALE AND INVERSION.

Altogether 94 patients with perirectal abscesses and/or fistulae in ano were tested for lymphogranuloma venereum in a Washington, D.C., clinic. They included men and women of low socio-economic status, many of the men being overt psycho-sexual hermaphrodites. The findings were compared with those in a control group of similar sex distribution (females, male homosexuals, male heterosexuals). All persons in the study were tested for lymphogranuloma venereum by the complement-fixation and Frei tests. Homosexuals and persons with rectal lesions were also examined by proctoscopy.Among other findings, a significantly higher frequency of Frei reactors or positive complement-fixation reactions was observed among patients (both male and female) with abscesses than among the controls and among male homosexuals than heterosexuals.The author concludes that lymphogranuloma venereum should be excluded in the differential diagnosis of perirectal abscess and fistual in ano, that homosexuals should be routinely tested for lymphogranuloma venereum, and that sexual perversion should be considered in male patients with ano-rectal disease of lymphogranuloma venereum origin.
