The inflammatory bowel disease (IBD) is sometimes complicated by the development of a psoas abscess. We recently encountered three patients of IBD with psoas abscess. Two patients had Crohn's ileocolitis and one with ulcerative colitis. During 1979-1984, 23 patients with psoas abscess due to a variety of underlying disease processes were seen at our institution. At the same time period, 483 cas...

Introduction In India, 5% of patients with skeletal tuberculosis develop a psoas abscess as a complication.1 About 70% of psoas abscess cases have been reported in the age group of 10 to 17 years, but patients of more than 40 years of age usually develop psoas abscess due to secondary origin with a slight male preponderance.2 In infants, psoas abscess is rarely reported.3 We report a 6-month-ol...

Psoas muscle abscess associated with emphysematous urinary tract infection is very rare. There were very few reports about urinary tract infections such as renal abscess, perinephric abscess, and emphysematous pyelonephritis complicated with psoas muscle abscess; however, psoas muscle abscess associated with emphysematous cystitis has not yet been reported. Here, we report a case of bilateral p...

BACKGROUND Psoas abscess is a rare condition consisting of pyomyositis of the psoas. The worldwide incidence was 12 cases per 100,000 per year in 1992, but the current incidence is unknown. Psoas abscess can descend along the psoas sheath and reach the inner upper third of the thigh, but only infrequently does it penetrate the sheath and involve the thigh adductors. Because of insidious clinica...

We describe a case of right ilio-psoas abscess caused by stump appendicitis 14 years after open appendectomy. Stump appendicitis is a rare complication of appendectomy. Right ilio-psoas abscess was diagnosed in an immune-competent patient and treated by ultrasound guided percutaneous drainage twice without identifying the cause of the abscess. The patient did not improve until diagnostic laparo...

Primary psoas abscess is a distinct clinical entity with vague clinical presentation and obscure pathogenesis, although the literature regarding it is sparse. Psoas muscle abscess is an uncommon clinical phenomenon, extremely difficult to diagnose and needs to be investigated with considerable thoroughness. We emphasize the importance of ultrasonography and computed tomography along with role o...

We describe a series of twelve patients with a psoas abscess seen in a three-year period in a university hospital and a large teaching hospital in the Netherlands. In our series, five of the 12 patients had a primary psoas abscess. The predisposing conditions were intravenous drug use, diabetes mellitus, prostate carcinoma and haematoma in the psoas muscle in a patient with haemophilia A. Seven...

Psoas abscesses are classified into primary or secondary according to infectious etiology. However, the psoas abscess caused by actinomycete together with Escherichia coli infection is very rare. Here we report a case of psoas abscess caused by actinomycete together with Escherichia coli infection in a young woman. The disease was treated successfully. A literature review of psoas abscess in re...

BACKGROUND Psoas abscess complicating tuberculous spondylitis is a rare morbidity in extrapulmonary tuberculosis. There are no established guidelines for evaluating the clinical response of psoas abscess. Although several studies have shown that positron emission tomography-computed tomography with 18 F-fluorodeoxyglucose can play a potential role in diagnosing multifocal tuberculosis and monit...

Psoas abscess in neonates and infants are rare. Primary psoas abscesses are said to be more common in young children. Limping, fever and abdominal pain has been described to be the way psoas abscesses usually present. The authors describe the unusual presentation and successful treatment of a young child with a unilateral psoas abscess secondary to advanced spondylodiscitis.
