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...

Psoas abscess is a rare condition where infection spreads from a nearby or distant septic focus to the psoas sheath. The causative bacterial organisms at distal sites reach the psoas via lymphatic or hematogenous spread, whereas infection from nearby sites that include the urinary system reaches the psoas directly. There are few reports that account for bacterial infection after endourological ...

BACKGROUND Primary psoas muscle abscess is rare and can be difficult to diagnose, particularly during pregnancy. CASE To our knowledge, this is the first case of primary psoas muscle abscess diagnosed during pregnancy. Clinical investigation did not reveal any infection spreading from adjacent structures. Surgical drainage and simultaneous Cesarean delivery of the infant, combined with approp...

Psoas abscess is a collection of pus within the psoas muscle compartment that can access the hip joint in rare opportunities through the psoas bursa. Usual treatment involves articular debridement at early diagnosis and psoas drainage in an open fashion or by to mographic guided percutaneous drainage, but when not suspected, secondary arthritis and high incidence of septic arthroplasty loosenin...

Metastasis of gastroesphageal junction (GEJ) adenocarcinoma in skeletal muscle is rare and primary sites for skeletal muscle metastases are usually lung, renal and colorectal cancer. We have encountered with the first case report of solitary psoas muscle metastasis of GEJ adenocarcinoma. Here we describe a 65 years old man was diagnosed with GEJ adenocarcinoma in Gastroenterology Department, Im...

Loss of mass and functional capacity of skeletal muscle is a major cause of morbidity in older individuals as well as in patients affected by a host of acute and chronic conditions including infectious disease, endocrine and metabolic disorders, organ dysfunction, immunological disease, vascular diseases, haematological disorders, and malignancies. Quantitative approaches are required to diagno...

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...

Primary neoplasms in the psoas muscle including schwannoma and soft tissue sarcoma with secondary cystic degeneration are rare entities. They are difficult to distinguish from psoas abscess purely based on radiological findings. Malignant fibrous histiocytoma (MFH) in the retroperitoneum is an uncommon entity in contrast to liposarcoma and leiomyosarcoma. Psoas abscess is a common infection in ...

While not proven definitively, the hypothesis that intra-articular psoas tendon release allows fluid to track into the retroperitoneal space has been widely accepted. This study attempts to identify the path through which fluid enters the pelvis and retroperitoneal space. Six hemi-pelvis human cadaveric specimens were utilized for this study. 3 specimens underwent a capsulotomy and psoas tendon...
