Chronic encapsulated intracerebral hematoma is a rare clinicopathological entity. The authors reported a case of a 52-year-old male who presented with progressive sensory disturbance of the left extremities three weeks prior to admission. Plain CT and MRI scans revealed a subcortical mass in the right temporal lobe associated with extensive peritumoral edema and intratumoral hemorrhage (mixed intensity on T1WI, low intensity on T2WI). There was a ring-like enhancement with GdDTPA. These findings strongly suggested metastatic melanoma associated with intratumoral hemorrhage. During the operation, the mass appeared partly at the surface of the brain and was easily extirpated totally. Histologically, the specimen showed chronic encapsulated hematoma with a thick, fibrous capsule and there was no evidence of neoplasm. The postoperative course was uneventful and follow up CT scan showed disappearance of the mass and the surrounding edema. The relevant literature was reviewed, and the pathogenesis of this entity was discussed.
