Psoas abscess: a complication of Crohn's disease.

Between 1971 and 1978 at St Mark's Hospital and St Bartholomew's Hospital, 8 patients were seen with a psoas abscess complicating Crohn's disease. All patients had a long history of disease and the diagnosis was usually obvious on clinical grounds. The abscess was drained in all patients and 5 required drainage on more than one occasion. The underlying Crohn's disease was treated surgically in all patients. Seven patients are now well, although 2 have required further excisional surgery; 1 patient died 2-years after the first drainage of the psoas abscess.

[Psoas abscess exteriorized in the groin revealed late after acute pancreatitis].

Two cases of psoas abscess complicating acute necrotizing pancreatitis are reported. These cases were particular because the abscesses exteriorized in the groin and symptoms were misleading. The abscesses were detected late, three and five months after the beginning of the pancreatitis respectively. The difficulties in diagnosis and the long delay to diagnosis are emphasized as possible sources of superinfection.

[Psoas abscess in Crohn's disease. Preoperative evaluation and surgical attitude].

Three patients with psoas abscess secondary to Crohn's diseases are reported with the aim of discussing the diagnosis and surgical management of these patients. It is concluded that computerized tomography is the method of choice for the diagnosis and follow up of this complication. Surgery should be individualized but in stable patients abscess drainage should be attempted in addition to resection of the intestine involved. Finally, given the great risk of pulmonary thromboembolism in these patients, intensive prophylactic anticoagulant therapy is required.

Ilio-psoas abscess in a neonate.

A full-term, small-for-gestational-age, neonate was born 4 days after rupture of the membranes. On the 5th day of life, she developed sepsis due to Klebsiella pneumoniae. On the 18th day of life, the right hip was noted swollen with limited range of motion, but it was painless on passive movements. Ultrasonography revealed abscess of the right ilio-psoas muscle with normal appearance of the right hip joint. Surgical incision and drainage and antibiotic administration resulted in a gradual full recovery. Ultrasonography can confirm the diagnosis of this exceptional clinical entity in neonates, which is difficult to differentiate from septic arthritis of the hip.

[Psoas abscess: report of 8 cases and review of the literature].

Eight cases of psoas abscesses (PA) are reported and a comparative study is made with other series as well as a review of the literature. Cases in our series are analysed and an assessment is made of microbiological etiologies, the presence of an origin and its spreading into the surrounding tissues or their primary character, and particularly the diagnostic and therapeutic usefulness of CT-guided percutaneous drainage. Diagnosis was ascertained by CT in all seven cases in which it was performed; percutaneous drainage was performed in five cases and allowed the microbiological categorization of the abscess and an appropriate antibiotic therapy. Laparotomy was performed in only one case; and in two other cases only antibiotics were administered. A favourable outcome occurred in seven out of the eight cases. One of the two patients treated with antibiotics only died. Blood cultures were positive in only three patients. In summary, PA in our series were secondary to bone, urologic or digestive origins in 87.5% of cases. With regard to the causative agent, 37.5% of cases were caused by S. aureus and 50% by gram negative and/or anaerobic organisms. The diagnostic yields of echocardiography and CT were 40% and 100%, respectively. Percutaneous drainage ascertained the microbiological diagnosis in 100% of cases when it was performed, as well as a therapeutic regimen associated with the use of antibiotics. No relapses were recorded in the follow-up of patients. Therefore, we believe that therapy of PA should be based on the association of percutaneous drainage and antibiotics.

Nocardia nova as the causative agent in spondylodiscitis and psoas abscess.

We describe here the first case of Nocardia nova spondylodiscitis accompanied by a psoas abscess due to spreading from pulmonary nocardiosis. Nocardia was cultured from all affected sites. After 1 year of an appropriate antimicrobial therapy and a surgical drainage of the abscess that was required, the patient's clinical condition had improved.

Percutaneous catheter drainage of tuberculous and nontuberculous psoas abscesses.

OBJECTIVE: To assess the utility of percutaneous catheter drainage in the management of tuberculous and nontuberculous psoas abscesses associated without any bony involvement or with minimal bony lesions that could not cause vertebral instability. MATERIALS AND METHOD: Eleven patients with psoas, iliopsoas and pelvic abscesses were drained under computed tomography and ultrasonography guidance. RESULTS: There were 15 (10 tuberculous, 5 pyogenic) abscesses in 11 patients. Six of the tuberculous abscesses and one of the pyogenic abscess were associated with vertebral involvement. Vertebral lesions were located in one or two vertebrae without causing any serious disturbance in the vertebral stabilization. In one case, the abscess was bilateral. Nine cases were drained under computed tomography guidance, while two cases were drained under both computed tomography and ultrasonography guidance. One session drainage was sufficient for abscess resolution in uniloculated cases. In the two of four multiloculated cases, catheter drainage was performed twice. Relapse of the abscess was found in only one patient. The mean abscess volume was 520 ml and mean drainage duration was 12 days. None of the cases required surgery. CONCLUSION: Percutaneous drainage, chemotherapy and additional external brace application with the cases associated with bony lesion may be used for treatment of tuberculous and nontuberculous unilocule and multiloculated abscesses.

Scrofuloderma of the scalp, psoas abscess, and caries spine: an unusual association.

An unusual association of scrofuloderma of the scalp, psoas abscess, and caries spine was seen in a 4-year-old girl. The diagnosis was confirmed by relative and absolute criteria. The peripheral T-lymphocytes and their subsets were within normal limits, although her immunohistopathological changes indicated an intermediary response across the spectrum depicting an unstable immunity. This may have been responsible for the silent spread of Mycobacterium tuberculosis and the current association.

Pyogenic psoas abscess: difficulty in early diagnosis.

AIM: To report on the clinical features, diagnosis, and treatment of psoas abscess (PA) with special attention to the presence of septic shock. PATIENTS AND METHODS: This study included 17 patients (mean age 66.2, range 43-81 years) with PA. Treatment consisted of intravenous administration of antibiotics and abscess drainage, either surgical or percutaneous with ultrasound guidance. RESULTS: The typical patients presented with fever >38 degrees C (16/17, 94%), pain in back, flank, or abdomen (15/17, 88%), hip flexion contracture with pain extension (14/17, 82%), and mass felt in the flank (5/17, 29%). All 8 patients without septic shock (100%) had the clinical triad (fever, pain in back, flank, or abdomen, and hip flexion contracture) as compared with 4 of 9 patients with septic shock (44%) (p = 0.012). The duration of symptoms before hospitalization was significantly shorter in the patients with septic shock (median 2, range 1-5 days) than in those without septic shock (median 18.5, range 11-63 days; (p = 0.0005). The mortality rates were 33% (3 of 9) and 0% (0 of 8) in the patients with and without septic shock, respectively (p = 0.071). CONCLUSIONS: PA patients with septic shock had a tendency to have nonspecific symptoms and an occult clinical course as compared with those without septic shock. A delay in diagnosis and treatment can result in a worse clinical outcome (death or totally disabled state). Increased awareness of this condition should lead to earlier diagnosis and treatment with improved outcomes.

Retroperitoneal schwannoma misdiagnosed as a psoas abscess: report of a case.

A retroperitoneal cystic mass compressing the right psoas muscle was found incidentally by ultrasonography in a 67-year-old woman. The radiological findings and a history of costal caries led us to suspect a psoas cold abscess. Ultrasound-guided needle aspiration was done to establish the diagnosis and to drain the content, but only a small amount of sterile fluid was obtained. The patient complained of neuralgia in her right leg at the time of puncture. Under the preoperative diagnosis of a neurogenic tumor, the mass was surgically resected, and found to be filled with old blood. The solid region consisted of a proliferation of fusiform cells, leading to a diagnosis of benign schwannoma. Retroperitoneal schwannoma is often misdiagnosed as an adjacent anatomical structure. Thus, we conclude that both microbiological and cytological examination of an aspiration specimen is important when psoas abscess is considered in a differential diagnosis.

Acute psoas abscess in a newborn infant.

A 1-month-old neonate was seen for an acute toxic illness, suggestive of septicemia. No obvious focus of infection was present. During attempted femoral venipuncture, purulent material, thought to originate from the right hip joint, was encountered. Because of this aspirate, as well as suggestive local signs, septic arthritis of the right hip was diagnosed. Arthrotomy failed to confirm the diagnosis, and on further surgical exploration a purulent psoas abscess was discovered. The patient made an uneventful recovery, and at follow-up 48 months later was asymptomatic with a normal clinical examination. This case illustrates the difficulty of differentiating acute psoas abscess from septic arthritis of the hip in the neonate.
