[Non-functioning adrenal cortical carcinoma: a case report--MRI findings].

A 42-year-old woman was admitted to our hospital complaining of dull left flank pain. Excretory urogram showed a downward compression above the left nephrogram. Computed tomographic scan and magnetic resonance imaging (MRI) revealed a left adrenal tumor with a non-homogenous inner density. The mass was hyperintense as compared to the liver on T2-weighted images of MRI. No endocrinological abnormalities were detected by laboratory examinations. We performed transperitoneal left adrenalectomy and nephrectomy under the diagnosis of non-functioning left adrenal tumor. The histological examination revealed adrenal cortical carcinoma without lymph node metastasis. The patient has been receiving 4.5g o,p'-DDD per day after the operation. There has been no evidence of recurrence or metastasis during the 7-month follow-up period.
