The sonographic features of eight surgically confirmed pheochromocytomas are described and correlated with pathologic findings. The purely solid masses were homogeneous or heterogeneous sonographically. Pathologic examination of the gross specimen provided explanations for the variety of sonographic findings. Two tumors had large cystic components due to old blood. Other hypoechoic areas corresponded to necrosis pathologically. Hyperechoic areas represented hemorrhage. Generally, pheochromocytomas are quite large, sharply marginated, and usually have a significant solid component with or without central necrosis or hemorrhage. Recognition of these features should facilitate their identification on sonography.
本文描述了8例经手术证实的嗜铬细胞瘤的超声特征，并将其与病理结果进行了对比。这些纯实性肿块在超声检查中表现为均匀或不均匀回声。大体标本的病理检查为各种超声表现提供了解释。2例肿瘤因陈旧性出血而有较大的囊性成分。其他低回声区在病理上对应于坏死。高回声区代表出血。一般来说，嗜铬细胞瘤体积较大，边界清晰，通常有显著的实性成分，伴有或不伴有中央坏死或出血。认识到这些特征应有助于在超声检查中对其进行识别。
