Chronic subdural hematoma in a 50-year-old man with polycystic kidney disease

The following case describes two spontaneous chronic subdural hematomas in one patient. The hematomas occurred on opposite sides. The patient had good blood pressure control and a normal creatinine. He was not receiving any anticoagulants or antiplatelet drugs. An angiogram was done after the second subdural collection was drained. There was no evidence of a vascular lesion. The possibility remains that patients with adult polycystic disease may be predisposed to develop spontaneous subdural hematomas in light of another report of five other cases.
