【摘要】：目的分析肾上腺囊性病变(ACL)的CT和MRI表现,提高对该病的认识和影像诊断水平。方法回顾性分析40例经手术病理证实的ACL的CT和MRI表现。32例行CT平扫,其中24例行增强扫描;3例行MRI平扫,其中2例行增强扫描;5例同时行CT和MRI扫描。结果非肿瘤性ACL 20例,其中内皮性囊肿8例,非肿瘤性假性囊肿7例,囊性淋巴管瘤2例,畸胎瘤1例,肾上腺血肿2例;肿瘤性20例,其中嗜铬细胞瘤9例,皮质腺瘤2例,皮质腺癌2例,神经母细胞瘤1例,神经纤维瘤2例,肾上腺转移瘤4例。ACL的大小、形态、囊壁(厚度、有无壁结节)、密度或信号、强化程度和方式等特征有助于非肿瘤性、(良性与恶性)肿瘤性囊性病变的鉴别。结论部分ACL的CT、MRI表现具有一定特点,术前可做出正确诊断,为临床治疗方案的选择及预后判断提供理论依据。
[Abstract]:Objective to analyze CT and MRI findings of adrenal cystic lesions (ACL) and to improve the recognition and imaging diagnosis of the disease. Methods CT and MRI findings of 40 cases of ACL proved by operation and pathology were retrospectively analyzed. Ct plain scan was performed in 32 cases, in which 24 cases were performed with enhanced CT scan and 3 cases with MRI plain scan, and 2 cases with enhanced CT scan and 5 cases with MRI scan were performed at the same time. Results there were 20 cases of non-neoplastic ACL, including 8 cases of endothelial cyst, 7 cases of non-neoplastic pseudocyst, 2 cases of cystic lymphangioma, 1 case of teratoma, 2 cases of adrenal hematoma, 20 cases of tumor, including 9 cases of pheochromocytoma and 2 cases of cortical adenoma. 2 cases of adrenocortical adenocarcinoma, 1 case of neuroblastoma, 2 cases of neurofibroma, 4 cases of adrenal metastasis. The features of degree and mode of enhancement are helpful in differentiating non-neoplastic cystic lesions from benign and malignant ones. Conclusion some ACL findings have some characteristics, which can be diagnosed correctly before operation and provide theoretical basis for the choice of clinical treatment scheme and the judgment of prognosis.
