摘要 目的探讨肾上腺原发性肿瘤的M R I表现特征与病理学基础的关系。方法回顾性分析经手术病理证实的原发性肾上腺肿瘤35例,观察其M R I表现特征及病理学特点,并评价其关系。结果皮质腺瘤表现为信号均匀的较小软组织肿块,病理上肿瘤均质,细胞富含类脂质。嗜铬细胞瘤表现为明显强化的信号不均匀软组织肿块,病理上肿瘤富含血管,多见坏死囊变。髓脂瘤表现为均匀、各序列高信号的肿块,病理上肿瘤含大量脂肪成分。皮质腺癌表现为周界不清的信号不均匀肿块,病理上肿瘤血管丰富,见出血坏死灶,有血管包膜浸润。节细胞神经瘤表现为信号不均的软组织肿块,病理上肿瘤神经细胞和纤维交织呈束状,见坏死囊变灶。浆细胞肉瘤为周界不清的不均匀信号软组织肿块,病理上瘤体由浆细胞构成,间质富含血管,见坏死灶。结论肾上腺原发肿瘤的M R I表现特征与其病理改变有一定关系。
