The CT scans in 25 patients without ileocecal pathology and 52 patients with ileocecal abnormalities were retrospectively reviewed. The ileocecal region was identified in 18/25 (72%) of patients without pathology. Thirty of 52 patients with ileocecal pathology had inflammatory disease: Crohn's (13), appendicitis (9), abscess (6), and typhlitis (2). CT was complementary to barium studies, demonstrating wall thickening, pericolonic inflammatory change, masses, fascial thickening, and fistulae. Twenty patients had malignancy: primary carcinoma (9), metastases (7), and lymphoma (4). In all patients with carcinoma a mass was identified. Pericolonic stranding represented tumor extension in 5/6 patients. Metastases were identified as extrinsic ileocecal masses in all 7 patients. Liver, mesenteric and omental metastases were present in 8/20 patients. In patients with lymphoma there was wall thickening and two had additional pericecal lymphadenopathy. In 2 patients with hypoalbuminemia, findings included: wall thickening, mesenteric, and subcutaneous edema.
对25例无回盲部病变的患者和52例有回盲部异常的患者的CT扫描结果进行了回顾性分析。在无病变的25例患者中，18例（72%）可识别出回盲部区域。52例有回盲部病变的患者中，30例患有炎症性疾病：克罗恩病（13例）、阑尾炎（9例）、脓肿（6例）和盲肠炎（2例）。CT是对钡剂造影的补充，可显示肠壁增厚、结肠周围炎症改变、肿块、筋膜增厚和瘘管。20例患者患有恶性肿瘤：原发性癌（9例）、转移瘤（7例）和淋巴瘤（4例）。所有患有癌的患者均发现有肿块。在6例患者中，5例结肠周围条索状影提示肿瘤浸润。7例转移瘤患者均表现为回盲部外生性肿块。20例患者中有8例存在肝、肠系膜和网膜转移。淋巴瘤患者表现为肠壁增厚，2例伴有盲肠周围淋巴结肿大。2例低白蛋白血症患者的表现为：肠壁增厚、肠系膜和皮下水肿。
