Abstract
Gastrointestinal stromal tumors (GISTs) usually present as a solid mass arising from the interstitial cells of Cajal, which often exhibit non-specific in laboratory test and features clinically varies with the size and location of tumors. Hereby, we report a case of jejunal GIST with cystic change mimicking as periappendicular abscess that could not be confirmed preoperation. A 45-year-old female was admitted to our hospital emergency department with increasing abdominal distension with pain in the right lower abdomen.
Physical examination revealed a large mass with peritoneal irritation sign in the right lower abdomen. A contrast-enhance computed tomography (CT) scan of the abdomen revealed a large cystic lesion located in lower abdominal, but the source of the mass could not be determined. Acute episode of chronic appendicitis with periappendicular abscess was suspected. Intra-operatively the mass was an 11 x 8 x 8 cm cyst with approximately 500 ml serous fluid present inside it arising from the anti-mesenteric border of the jejunum which was about 10 cm away from the duodenojejunal junction. The mass excised along with resection of the involved jejunal segment was done. The final diagnosis of a jejunal GIST was made by immunohistochemistry study. The patient recovered well postoperative. The latest CT scan did not show any evidence of recurrence or metastasis following a 19-month follow-up.
