@entity1 @entity697 @entity738 @entity706 @entity189 @entity854
BACKGROUND: We present the computed tomographic (CT) findings of @entity738 . METHODS: Five of 652 (0.9%) @entity1 who had undergone appendectomy for clinically suspected @entity697 over a 19-month period proved to have @entity738 . One @entity1 had surgery based on a clinical diagnosis of @entity697 . Four @entity1 (three @entity1 and one @entity1 ; age range = 14-39 years) underwent abdominal CT. The CT findings were retrospectively reviewed with special attention to the @entity854 . RESULTS: All four @entity1 presented with subacute clinical presentation. Enlarged appendices of 4.5 and 2 cm in diameter with thickened walls of soft tissue density were found in two @entity1 , and periappendicular inflammatory masses were found in the other two. Enlarged mesenteric lymph nodes and right lower quadrant fat stranding was seen in all four @entity1 . Histopathology showed numerous @entity738 within the inflamed appendix. CONCLUSION: Radiologists should be familiar with the rare entity of @entity738 in @entity1 examined by CT for suspected @entity697 . An insidious clinical presentation with CT findings of an exceptionally large appendix and associated periappendiceal inflammatory changes should raise the possibility of @entity738 or @entity189 or @entity706 .
