AbstractEncapsulated intracerebral hematoma is so rarely seen that only two cases have been reported, by Hirsh et al. Recently, we experienced a case of multilocular encapsulated intracerebral hematoma containing 9 to 10 capsules of different sizes. The capsules of the hematoma were easily dissected from the surrounding brain tissues and found to be grayish white in color, tough in hardness and 1 to 3 mm in thickness. The capsular contents ranged from very old to relatively new, which contents were hard on soft solid hematomas, liquid hematomas or xanthochromic fluid. These findings indicated the development of intracerebral hematomas with different chronic courses at different times. It is very interesting that the frequency of the convulsive seizure was almost consistent with the number of capsules. For etiology of multilocular intracerebral hematoma, either occult vascular malformation or bleeding from the sinusoidal channel layer of the capsules like that of chronic subdural hematoma is considered.
