Left-sided liver abscess in childhood.

Abscesses occur less frequently on the left side of the liver than on the right, and are implicated in a higher incidence of complications. Of a total of 124 children with liver abscesses seen at Red Cross War Memorial Children's Hospital from 1974 to 1990, 26 had left-sided and 98 right-sided lesions. A similar spectrum of organisms was cultured, and 20 (77%) of the left-sided abscesses were found to be caused by pyogenic organisms as opposed to 78 (79%) of those on the right. The remainder were of amoebic origin. In 5 patients with multiple abscesses involving predominantly the left side of the liver, the right side was also involved. These were excluded from further comparison of left and right liver abscesses. Of the remainder, 16 (62%) left-sided and 77 (83%) right-sided abscesses were solitary. Clinical features were similar in both groups but epigastric mass was more frequent in left-sided lesions. After an initially conservative management policy, surgical drainage was necessary in 87.5% of solitary left-sided liver abscesses as opposed to 64% of solitary right-sided abscesses. No intrapericardial ruptures were noted, but 2 pericardial effusions required drainage. There was no mortality but 3 patients with solitary left-sided abscesses ruptured. The important role of ultrasound in the diagnosis and follow-up period is stressed. Patients with solitary left-sided abscesses are identified as being at risk. Abscess drainage is recommended in this group.

MR findings in human fascioliasis.

Fasciola hepatica is a trematode of herbivorous mammals, and man is infected by accidental ingestion of contaminated raw aquatic vegetables or water. There have been many reports on computed tomographic and cholangiographic features of human fascioliasis. However, findings of magnetic resonance (MR) imaging have not been reported. Hepatic fascioliasis produces three types of lesions in MR images arranged in tract-like fashion. The outermost area presents as an iso-signal area in T1WI, with slightly higher signal intensity in T2WI and diffuse enhancement after i.v. contrast. The second type presents as a well defined low signal area in T1WI, not enhanced, and also shows low signal intensity in T2WI. The third type has low signal intensity in T1WI, is not enhanced, and has high signal intensity in T2WI which is similar to fluid-containing inflammatory lesions such as pyogenic abscess. These findings suggest various changes associated with traumatic hepatitis caused by the migration of the worm in the liver. This diverse signal intensity can be a suggestive finding of fascioliasis.

[The Corynebacterium pyogenes infection in cattle. 1. Incidence of the pathogen].

Reported are the incidence of Corynebacterium pyogenes together with different pathological changes as well as the existence of latent Corynebacterium pyogenes infections and their widespread occurrence. Corynebacterium pyogenes was established from 609 in 2,130 samples of pathological processes, accounting for 28.6%. The pathogen was cultivated from various processes, including enlarged tail lymph nodes (61.1%), tail phlegmons (56.3%), abscesses (49.1%), epiphysiolyses (45.2%), liver abscesses (31.8%), panaritia at beginning of fattening (20.5%), aborted foetuses (14.9%), foetal membranes in cases of incarcerated placenta (12.0%), and panaritia on end of fattening (3.4%). The same pathogenic microorganism was recorded from nine per cent of apparently intact heifer udders, before pasturing. Corynebacterium pyogenes was cultivated also from nasal mucous membrane (8.4%) and retropharyngeal lymph nodes (37.2%). The highest detection rate was 71.6%, obtained from the tonsils.

[Ultrasound-guided puncture. Modern treatment of liver abscess].

The treatment of liver abscesses has benefitted from progress in imaging, particularly ultrasonography which allows simple and reliable aspiration and drainage. A series of 32 cases is reported, consisting of 29 pyogenic abscesses and 3 amoebic abscesses. Eighty-one per cent of patients were cured by aspiration and/or drainage, while 19% of patients had to be operated. The mean hospital stay was 11 days. Failures of ultrasound-guided aspiration are essentially due to multifocal abscesses caused by multiple organisms.

[Strategy in sonographic suspicion of a parasitic disease of the liver (echinococcosis and amebic abscess)].

Ultrasonography is a widely used, early available and well established method in the examination of abdominal symptoms. The strategy for investigation of focal liver lesions, suspected to be parasitoses of the liver (echinococcus cysts or amebic abscess) is shown. The ultrasonographic morphology of echinococcosis and amebic abscess is characteristic, although it is imperative to distinguish these lesions from other tumorous or cystic lesions. The diagnosis suspected through case history and clinical appearance is confirmed by modern serological tests in 90 to 95% of echinococcosis and in 95 to 100% of amebiasis. Fine-needle aspiration guided by ultrasound is indicated in cases of a negative serological result in order to exclude a pyogenic abscess. This evaluation allows a fast diagnosis and efficient therapy.

Unusual manifestations of salmonellosis--a surgical problem.

From January 1981 to December 1992, of 6250 cases of salmonellosis treated at the Christian Medical College and Hospital, Vellore, India, 100 patients with focal pyogenic infection caused by salmonellae required surgical intervention in addition to medical therapy. Thirty-one had involvement of the hepatobiliary system, and 10 more had other intra-abdominal infections. Involvement of bone and joint as well as soft tissue constituted 15% each. The site of infection in patients with soft tissue abscesses included skin (7), parotid (2), thyroid (2), breast (1) inguinal node (1), branchial sinus (1) and injection site (1). Three patients had arterial infections. Noteworthy among the cases of genital infections was one case of salmonella infection in a pre-existing hydrocele, and one case of epididymo-orchitis with a loculated salmonella infection. Salmonella infection in a pre-existing ovarian cyst was seen in a patient with endometriosis. The salmonella serotypes most frequently encountered were S. typhi (36) and S. typhimurium (36), followed by S. paratyphi A (15). The importance of recognition of these protean manifestations of salmonellosis in an endemic setting is discussed. The microbiological evaluation of properly obtained specimens is mandatory in such unusual pyogenic infections.

[Weber-Rendu-Osler disease: pulmonary arterio-venous malformation with shunt disclosed after 5 occurrences of purulent meningococcal encephalitis].

Hereditary hemorrhagic telangectasis or Weber-Rendu-Osler disease is associated with the presence of capillary malformations with pulmonary visceral shunts. These shunts are the cause of recurrent infections of the nervous system by loss of the anti-infectious lung filter. Hereditary hemorrhagic telangiectasis was diagnosed in a 68-year-old woman with a history of epistaxis, cutaneous telangectasis, purulent and pyogenic brain abscesses and meningitis. Outcome was favorable with antibiotic therapy. Ventilation as well as chest x-ray, brain scan and liver ultrasongraphy were normal. Blood gases showed a PO2 at 63 mmHg in ambient air and 62 mmHg with FiO2 = 1. There was no dyspnea or cyanosis nor any apparent polycythemia. Pulmonary angiography showed and arteriovenous malformation in the lower right lobe. Endovascular embolization was achieved with coils and N-butyl-cyano-acrylate glue which enabled angiographic occlusion and normalization of gas exchange: on ambient air the PaO2 = 71 mmHg and on FiO2 = 1, PaO2 was 359 mmHg. A true shunt was suspected on account of the association of hereditary hemorrhagic telangiectasis and recurrent meningitis. The diagnosis was suspected on blood gases alone.

Focal inflammatory diseases of the liver.

Inflammatory lesions constitute an important subgroup of focal liver lesions. They may mimic primary or metastatic neoplastic lesions and their differentiation from neoplasia is clinically very important since management of the patient significantly changes. Radiologists should have an important role in both the diagnosis and therapy of these lesions by performing percutaneous aspirations and drainages. In this review we discussed the radiological findings of pyogenic abscesses, amebic abscesses, candidiasis, tuberculosis, hydatic cysts, fascioliasis, ascariasis, schistosomiasis, and sarcoidosis with a special emphasis on US, CT and MR characteristics.

Pseudomonas pseudomallei liver abscesses: a clinical, laboratory, and ultrasonographic study.

Ultrasonography revealed evidence of liver abscess in 126 patients who were admitted to one hospital in northeastern Thailand over a 3-year period. There were 50 cases for which a pyogenic bacterial etiology was confirmed; 34 cases (group 1) were caused by Pseudomonas pseudomallei (nine patients died) and 16 cases (group 2) were caused by other bacteria (two patients died). Melioidosis was associated with anemia and underlying diabetes or renal disease; right-upper-quadrant pain and jaundice were more common in group 2 (P less than .05). Blood cultures were positive for bacteria in 68% of group 1 and 50% of group 2. Chest radiographs revealed abnormalities in 17 of 30 group 1 patients and 6 of 12 group 2 patients. The radiographic appearances of a blood-borne pneumonia suggested melioidosis. The serum indirect hemagglutination assay for antibodies to P. pseudomallei was of limited value in differentiating the two types of abscesses. Multiple hypoechoic areas on ultrasonography were significantly associated with melioidosis (P less than .01); associated splenic abscess occurred in 19 group 1 patients but only one group 2 patient (2-107, 95% confidence interval; odds ratio, 19). In an area where P. pseudomallei is endemic, these characteristic ultrasonographic findings should prompt immediate treatment for melioidosis.
