BACKGROUND Pyogenic abscess of psoas muscles is a rare condition. Psoas abscess due to methicillin-resistant Staphylococcus aureus is an emerging and rare infection and so far the related data are scarce. CASE PRESENTATION We report the rare case of primary and bilateral large psoas abscesses due to methicillin-resistant Staphylococcus aureus in a 54-year-old Arab Jordanian woman with breast ...

Acute cauda equina syndrome secondary to a spinal epidural abscess as a result of a psoas abscess is very uncommon. We report the case of a 64-year old with a 6-day history of left hip pain, which progressively worsened until she presented to the emergency department with systemic infective symptoms and classical acute cauda equina syndrome. A good clinical outcome was achieved by urgent poster...

From 1976 to 1984, 43 patients with psoas abscess were seen at the Mayo Clinic. Intestinal disease, including Crohn's disease, diverticulitis, and carcinoma, was the most frequent cause (14 patients). Eleven patients had osteomyelitis, five had postoperative complications, four had a foreign-body reaction, and three had a primary staphylococcal abscess. Two patients each had extension of a prim...

BACKGROUND AND PURPOSE The relationship between prosthetic hip infection and a psoas abscess is poorly documented. We determined the frequency of prosthetic hip infections associated with psoas abscesses and identified their determinants. METHODS We conducted a 2-year observational study. Data from patients with psoas abscesses that were associated with prosthetic hip infections were examined...

Infected pseudocyst as a consequence of tropical pancreatitis presenting as psoas abscess is unusual. We report a 40-year-old man who presented with pain in the right lumbar region. CT and MRI of the abdomen revealed pancreatic pseudocysts with abscess formation in the psoas muscle and evidence of chronic calcific pancreatitis. He was managed by percutaneous drainage of the abscess along with a...

Staphylococcus Aureus is a Gram-positive cocci bacteria which had been found to be the causative organism in over 88% of patients with primary iliopsoas abscess. We report the case of a 53-year-old diabetic woman with end-stage renal failure diagnosed with left iliopsoas abscess with a catheter-related infection. Computed tomogram (CT) of abdomen and pelvis revealed hypodense lesions of left ps...

Malignant metastasis to the psoas muscle is rare. We report a case that clinically mimicked psoas abscess that was subsequently proven to be from metastatic disease secondary to adenocarcinoma of the duodenum. A 62-year-old male presented with a seven-month history of right lower quadrant abdominal pain and progressive dysphagia. CT scan of abdomen-pelvis revealed a right psoas infiltration not...

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...

psoas abscesses could originate from an adjacent source of infection in the abdominopelvic cavity known as a secondary complication of acute appendicitis. however, it is considered as a very rare event when occurring late after the presentation of appendicitis. whether it is the source or complication of acute appendicitis following appendectomy remains unclear. a 25-year-old man was admitted t...
