Abstract
A 76-year-old woman was admitted to our hospital complaining of bloody stool. CT scan of the abdomen showed a mass connecting with the cecum. Magnetic resonance imaging scan showed the mass with low intensity in T1 and T2-weighted images. Colonoscopy demonstrated an ulcer around the appendiceal opening, so we clipped there. Angiography and 99mTc-HSA scintigraphy disclosed that there was no bleeding. The postclipping course was uneventful, and she was discharged from the hospital.
She was re-admitted to our hospital complaining of bloody stool 2 months later. Colonoscopy demonstrated that there was no bleeding and we performed a biopsy from an ulcer around the appendiceal opening. The biopsy suggested no evidence of malignancy. CT scan of the abdomen showed a mass connecting with clip. We diagnosed it as an appendiceal tumor and performed ileocecal resection.
On microscopic examination, inflammatory infiltrate was present in the appendiceal lumen, and the mass around the appendiceal opening was an inflammatory tumor. The findings were compatible with the diagnosis of appendicitis.
