title: [Hyperdense renal cyst associated with papillary adenoma: a case report].
abstract: An abnormal shadow in the chest of a 57-year-old male was detected during a medical checkup and careful investigation revealed a left posterior mediastinal tumor (neurinoma) and a clearly demarcated homogenous mass with dimensions of 16 x 12 mm and computed tomographic (CT) value of 79 H.U. in the superior pole of the right kidney. The content solution was sticky and blackish-green. Neoplastic degenerations of 8 x 4 and 5 x 5 mm were seen in the cyst. Partial nephrectomy, which included the cystic section, was conducted and papillary adenoma was pathologically diagnosed. Nine years after the operation, the patient is alive and neither relapse nor other abnormalities were detected.
