Abstract
- PURPOSE: To evaluate the CT findings of peritonitis associated with continuous ambulatory peritonealdialysis(CAPD). MATERIALS AND METHODS: We retrospectively analyzed CT scans of 14 symptomatic patients withperitonitis after CAPD. Diffuse abdominal pain was present in 11, fever in two, and abdominal mass with vomitingin one. The mean duration of CAPD ranged from 10 months to 5 years(mean : 3.9 years). On abdominal CT, weevaluated the presence and location of ascites, bowel wall thickening, cocoon formation, the pattern ofenhancement of peritoneal thickening, the presence of calcifications in the peritoneum, and mesenteric and omentalchange. RESULTS: On enhanced CT, multiloculated ascites was observed in all cases(n=14) ; it was located mainlyin the pelvic cavity with small multi-loculated fluid collections in the peritoneal cavity (n=13), including thelesser sac(n=3). In one patient, ascites was located in the space between the greater omentum and anteriorperitoneal surface. CT showed ileus in 12 cases, small bowel wall thickening in 11, and cocoon formation in five.Uneven but smooth thickening of the peritoneum, with contrast enhancement, was seen in eight cases, and in five ofthese, peritoneal thickening was more prominent in the anterior peritoneum. Other findings included reticularopacity in two cases, hematoma of the rectus muscle in one, and umbilical hernia in one. CONCLUSION:Multiloculated fluid collection, ileus, small bowel wall thickening, uneven but smooth peritoneal thickening, andcocoon formation appear to be CT features of CAPD peritonitis.
