Abstract:
A case of primary adrenal carcinoma that showed a decreased signal in part of the tumor on chemical shift magnetic resonance imaging (CSI) is reported. The patient had clinical symptoms of Cushing syndrome. The tumor was a discrete right adrenal mass about 3.4 cm in largest diameter. It was surgically removed and diagnosed as adrenal carcinoma histopathologically. Two portions where clear cells were prominent were recognized. These areas probably contributed to the signal loss on CSI.
