Although rare, clostridial infections associated with hip arthroplasty can cause fulminant tissue necrosis, septic shock, and mortality if not promptly diagnosed and treated. Among causative organisms, Clostridium septicum is particularly notable because of its strong association with occult gastrointestinal malignancies, especially colon cancer. Early detection using radiography and computed tomography (CT), combined with aggressive surgical debridement and targeted antimicrobial therapy, is essential for survival. This article presents a clinically instructive case involving an elderly di...

  Advanced CT Imaging Diagnosis, Pathophysiology, and Management — A Clinical Radiology Case Study Abstract Mechanical Small-Bowel Obstruction (SBO) is one of the most common surgical emergencies encountered in emergency medicine and radiology. Rapid diagnosis using advanced imaging—particularly computed tomography (CT) —is essential to prevent complications such as bowel ischemia, necrosis, and perforation. This column presents a radiology case study of Mechanical Small-Bowel Obstruction caused by small-bowel volvulus , integrates current global literature, and discusses pathophysiology, epidemiology, clinical presentation, imaging features, differential diagnosis, diagnostic strategies, treatment approaches, and prognosis . 1. Introduction Mechanical Small-Bowel Obstruction (SBO) is a critical gastrointestinal emergency characterized by physical blockage of the intestinal lumen , preventing the normal passage of intestinal contents. Mechanical SBO accounts for ...
