Computed Tomography Detection of Schistosomal Appendicitis

Expecting the Unexpected: Schistosomial Appendicitis in Nonendemic Area

“…8 9 However, the incidence of schistosomial appendicitis in endemic areas is reported to be between 0.02 and 6.3% 10 This represents over quarter (28.6%) of chronic appendicitis. 11…”

“…8,9 However, the incidence of schistosomial appendicitis in endemic areas is reported to be between 0.02 and 6.3% 10 This represents over quarter (28.6%) of chronic appendicitis. 11 Histological examination is the gold standard diagnosis of schistosomial appendicitis. Colonic mural calcification on preoperative computed tomography scan can raise suspicion for schistosomal appendicitis, but this is not specific and can be found in other colonic diseases such as sclerosing encapsulating peritonitis, phlebosclerotic chronic ischemic colitis, mucinous adenocarcinoma, and leiomyosarcoma.…”

Schistosomiasis Eggs Causing Acute Appendicitis

“…CT scan helped to diagnose these types of cases by obvious clue that is the calcification around the appendix [8]. Furthermore, CT scan can recognize the signs of S. japonicum infection [9].…”

“Right Iliac Fossa Pain”: More Than Meets the Eye

“…10 Since there is no pathognomonic clinical or operative finding, careful evaluation for the presence of intestinal or appendiceal mural calcification on CT will therefore alert the clinician to the possibility of underlying schistosomal infection, and the potential need for treatment with antihelminthic drugs, as seen in the case reported by Tang and his colleagues. 11 Colonic calcification seen with schistosomiasis infection should be differentiated from other causes such as phlebosclerotic colitis, renal failure, hyperphosphataemia (including treatment with lanthanum), mucinous adenocarcinomas, and leiomyomatous tumours of the colon and rectum. Phlebosclerotic colitis usually involves the right-sided colon as compared with distal colonic involvement in schistosomiasis.…”
