title: A chronic intracerebral fluid hematoma.
abstract: Intracerebral hematoma usually resolves and a chronic fluid hematoma is rare. We describe a rare case of intracerebral fluid hematoma. This report describes a case of intracerebral fluid hematoma mimicking a brain tumor and discusses the characteristics of this condition. A 70-year-old woman had a six-month history of memory disturbance. Computed tomography scan showed a low-density lesion with a partial high-density area in the right frontal lobe. MRI revealed a lesion of the main cystic portion showing high intensity on both T1 and T2 weighted images with a low-intensity solid portion in the anteromedial side. The lesion was adjacent to the lateral ventricle. Craniotomy was carried out and the lesion was removed. Pathological examination of the solid portion revealed that the diagnosis was reactive changes due to intracerebral hemorrhage. In our case, there was a possibility that the hematoma was diluted with cerebrospinal fluid, and coagulation might have been prevented.
