摘要
目的探讨恶性嗜铬细胞瘤的CT特征。方法对5例经手术、病理及随访证实的恶性嗜铬细胞瘤影像资料进行回顾分析。结果右肾上腺区肿块3例,左肾前方肿块1例,胰腺略下方腹主动脉旁肿块1例。肿瘤最大径9.0 cm,最小径2.7 cm,CT平扫肿瘤呈等密度或等低混杂密度影,实性部分,尤其周边部分强化明显而持续,中心部坏死区无强化。伴腰椎、骨盆、肺、肝转移瘤。结论CT是诊断恶性嗜铬细胞瘤的可靠方法。
Objective To investigate the computerized tomography （CT） features of malignant pheochromocytoma so as to reduce misdiagnosis. Methods Five cases of malignant pheochromocytoma were verified by operation, pathology, or follow-up. Their CT findings were analyzed retrospectively. Results Of the 5 cases, 3 were located in the adrenal glands, 1 in front of the left kidney, and 1 beside the pancreas and the abdominal aorta. The maximal diameter of the mass was 9 era, and the minimal diameter was 2. 7 era. The tumors showed equal density, or equivalent or low farraginous density mass in plain scan CT, with marked or extraordinary enhancement in the rims of the tumors. There existed tumor metastases to lumbar spine, pelvis, lung and liver. Conclusion CT is a reliable method to diagnosing malignant pheochromocytoma.
