极大部分的肾上腺皮质腺瘤常因其分泌功能而引起柯兴氏症。一般在瘤体很小时就能发现。但亦有极少数肾上腺皮质腺瘤并无分泌功能,早期无症状,仅在其体积增大,产生压迫症状或腹部触及块物时才被发现,而且常被误诊为脾肿大或其他性质的肿块。本院遇见1例,误诊为巨脾而手术。报 A large proportion of adrenocortical adenomas often cause Cushing’s disease due to their secretory function. It is usually found when the tumor is very small. However, few adrenocortical adenomas have no secretory function. They are asymptomatic at the early stage and are found only when they are enlarged in size, produce oppressive symptoms, or have abdominal palpable masses, and are often misdiagnosed as splenomegaly or other types of Lumps. The hospital met one patient and was misdiagnosed as a splenomegaly and operated. Report
