Typhlitis in a 54-year-old woman who had undergone total abdominal hysterectomy and bilateral salpingo-oophorectomy and chemotherapy for stage IIIC serous papillary carcinoma of the ovary. The patient presented with severe abdominal pain and fever. (a) Axial CT scan obtained following intravenous contrast material administration shows gross thickening of the cecal wall with mucosal enhancement (arrow), findings that are consistent with typhlitis. (b) Coronal CT scan shows less extensive involvement of the ascending colon, which has a thickened wall with a “thumbprint” appearance. There is surrounding free fluid in the right flank and pelvis.
