Abstract:
Objective: To observe CT manifestations of systemic lupus erythematosus (SLE) involving digestive tract. Methods: Data of 17 cases with SLE involving digestive tract were retrospectively analyzed. All 17 patients underwent conventional plain CT scanning, while 15 among them received contrast-enhanced CT scanning. The specific location, thickness of intestinal wall, CT signs and accompanying manifestations of the lesions involving digestive tract were recorded. Results: Stomach involving was found in 8 cases, while involvement of duodenum, jejunum, ileum, ascending colon, transverse colon, descending colon, sigmoid colon and rectum were observed in 2, 9, 9, 9, 1, 6, 8 and 8 cases, respectively. CT manifestations included intestinal wall swelling and thickening in 15 cases, "concentric circle sign" in 12 cases, "target sign" in 11 cases, also intestinal cavity expansion with gas accumulation and fluid accumulation in 13 cases, including 4 cases of pseudo-intestinal obstruction. Mesentery "comb sign" or "barrier-like" changes were noticed in 11 cases, while mesenteric fat gap was found blurred in 9 cases. There were 15 cases with abdominal and pelvic effusion, 12 of pleural effusion, 3 of pericardial effusion, 1 case of thrombi-embolization of superior mesenteric artery, 3 of splenomegaly, 5 of urinary tract abnormalities(including ureteric stenosis, bladder wall thickening, double kidney or ureteral effusion, etc) and 3 cases of epipolic appendagitis. Conclusion: Abnormalities of digestive tract wall and mesentery are typical CT manifestations of SLE involving digestive tract.
