INTRODUCTION Psoas abscess is a recognized but under-diagnosed complication of prosthetic hip joint infections. CASE REPORT We report a case of a 68-year-old man with right and left hip arthroplasties performed 22 and 14 years ago, respectively, who presented with non-specific symptoms and was subsequently diagnosed with left psoas abscess on CT scan. Drainage of the psoas abscess was complic...

Spontaneous rupture of colon cancer, combined with psoas abscess formation, is rare. A 44-year-old male visited for back pain and left buttock mass. Abdominal computed tomography and magnetic resonance image revealed a large abscess in the left psoas muscle and in the left lower quadrant area. Ten days after incision and drainage, a skin defect around the left anterior superior iliac spine rema...

Pneumothorax secondary to septic pulmonary embolism (SPE) is rare but life-threatening. We herein report a long-term hemodialysis patient with psoas abscess caused by methicillin-resistant Staphylococcus aureus, associated with other muscle and splenic abscesses and SPE. Intravenous vancomycin treatment and percutaneous drainage of the psoas abscess rapidly improved her condition. However, the ...

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...
