多房性腎嚢胞の1例

Abstract

A case of multilocular renal cyst is presented. The patient, a 65-year-old female, who had had macroscopic hematuria since 1979, came to our hospital in 1986. Computed tomography demonstrated a cystic mass with septa enhanced by contrast medium. The lesion was located at the anterior aspect of the midportion of the left kidney. These findings suggested a multilocular renal cyst. Therefore, enucleation of the mass was performed after confirmation of the absence of malignant cells in the septum on the frozen slide. Histological diagnosis was the same as the clinical diagnosis. We reviewed 65 cases of multilocular renal cyst in Japan and discuss preoperative diagnosis and operative procedure.
