title: Heterochronic spontaneous rupture of bilateral renal cell carcinomas in a hemodialysis patient.
abstract: A 64-year-old man undergoing chronic hemodialysis was admitted under a shock state with macrohematuria and fatigue lasting for two hours. A blood analysis revealed severe anemia. Computed tomography disclosed a large right-sided perirenal hematoma. The patient was successfully treated with radical nephrectomy, leading to a histological diagnosis of spontaneous rupture of renal cell carcinoma (RCC). One year after rupture of the right RCC, he again developed macrohematuria and computed tomography revealed a left-sided perirenal hematoma. Radical nephrectomy followed by a histological examination revealed spontaneous rupture of the left-sided RCC. This case emphasizes the importance of conducting periodic imaging evaluations of chronic hemodialysis patients with renal cystic masses.
