Chronic encapsulated intracerebral hematoma(CEIH)with arteriovenous malformation(AVM)is rare. We report a case of CEIH shrinking after feeder embolization for AVM. A 60-year-old man experiencing headaches for 2 weeks was admitted to our hospital due to intracerebral hematoma detected by MRI. The hematoma was shown as a low-density mass lesion on CT scans. Angiography and enhanced MRI showed an AVM in the right temporal lobe associated with the CEIH. Mild disturbance of consciousness and headaches gradually worsened, as the CEIH grew. Before AVM resection, feeder embolization was performed. On the day after the embolization, symptoms improved and the CEIH shrunk in size. A week following the embolization, the AVM including the partial hematoma capsule was resected without neurological deficit. Previous literature showed similarities between CEIH and chronic subdural hematoma(CSDH)in clinical features and pathological findings of the capsule. This case indicated that feeder embolization might be a treatment option for CEIH with AVM, such as embolization of middle meningeal artery for intractable CSDH.
