Presentation
Bloody stools, and intermittent abdominal pain. On colonoscopy, a sigmoid mass was found. Referred for CT scan for better staging.
Patient Data
evidence of sigmoid loop central intussusception (colo colic) associated with bowel wall thickening due to tumoural infiltration
intussuscepted segment was approximately 23 mm thick and 72 mm in length
no evidence of perforation
no intra abdominal free fluid
hyperdense stones measuring about 2 mm and 6 mm along with the midpole of the right and left kidneys respectively
small bilateral renal cortical cysts
mesenteric panniculitis with a fat ring sign
thoracolumbar spine with DJD changes as endplate sclerosis with marginal osteophyte formation
Case Discussion
CT imaging findings were consistent with a sigmoid colon intussusception with a bowel wall thickening highly suspicious for primary colorectal malignancy.
