【摘要】：目的:探讨CT值测量在原发性肾上腺肿瘤诊断中的价值。方法:回顾性分析48例经手术和病理证实的原发性肾上腺肿瘤的CT表现,并进行肿瘤CT值测量。结果:9例醛固酮腺瘤CT值为-12~17HU,增强无明显强化;8例无功能性皮质腺瘤及10例皮质醇腺瘤CT值为28~45HU,肿瘤轻度均匀强化;3例嗜铬细胞瘤肿块3cm者密度均匀,CT值为40~55HU,3例嗜铬细胞瘤肿块3cm者密度不均,CT值为10~45HU,肿瘤组织显著强化;2例皮质腺癌肿块内密度不均匀,CT值为35~50HU,其内见低密度区及钙化影,呈不均匀强化;2例神经母细胞瘤密度不均匀,CT值为35~50HU,瘤内见不规则低密度区,瘤内均见钙化;6例肾上腺囊肿呈均匀性水样密度,CT值为0~15HU,增强扫描无强化;5例髓性脂肪瘤瘤内以脂肪密度为主,CT值为-50~100HU,无明显强化。结论:不同类型原发性肾上腺肿瘤因所含组织成份各异而呈现不同的CT值,肿块密度及强化程度与细胞形态、瘤内结构及血供密切相关,肿瘤密度测量可为原发性肾上腺肿瘤的诊断与鉴别诊断提供有价值的信息。
[Abstract]:Objective: to evaluate the value of CT value measurement in the diagnosis of primary adrenal tumors. Methods: Ct findings of 48 cases of primary adrenal tumors proved by surgery and pathology were retrospectively analyzed. Results the CT value of 9 cases of Aldosterone adenoma was -12 ~ 17 HUU, the CT value of 8 cases of nonfunctional cortical adenoma and 10 cases of cortisol adenoma was 2845 HU.Three cases of pheochromocytoma with mild homogeneous enhancement were 3cm. In 3 cases of pheochromocytoma with 3 cm mass, the CT value was 1045 HUT, and the CT value was 35 ~ 50 HUU in 2 patients with significantly enhanced tumors. The low density area and calcification were found in the lesions. In 2 cases of neuroblastoma, the CT value was 35 ~ 50 HUT, and the irregular low density area was found in the tumor. In 6 cases of adrenal cysts, the CT value was 0 ~ 15 HUU, and the CT value in 5 cases of myelolipoma without enhancement was -50 ~ 100 HU.Conclusion: there is no obvious enhancement in different types of primary kidney. Adenoma presents different CT values due to its different tissue components. Tumor density and enhancement are closely related to cell morphology, tumor structure and blood supply. The measurement of tumor density can provide valuable information for the diagnosis and differential diagnosis of primary adrenal tumors.
