Introduction: Nontraumatic splenic rupture is a rare event. Bladder cancer usually metastasizes to the lymph nodes, bone, lung, liver and peritoneum, but rarely in the spleen.
Clinical findings: We present a rare case of spontaneous splenic rupture in a 72-year-old male due to metastatic infiltration of high-grade bladder cancer.
In the 12th day after radical cistoprostatectomy an abdominal CT scan is made due to persistent febrile spikes and persistent leucocytosis. The CT scan showed spleen rupture, in at least two foci, associated with splenic hematoma and active bleeding.
Diagnosis & Treatment: An urgent splenectomy was made, with no postoperative complications.
Histological examination revealed metastases from poorly differentiated urothelial carcinoma, infiltrating the capsule and perisplenic fat.
Conclusions: Spleen is an extremely rare site of bladder metastasis. Clinical history and histological study play a pivotal role in determining the correct diagnosis. Emergency splenectomy remains the standard of care.
