Calcified intracranial haematoma associated with chronic subdural hygroma.

Bulging of a hemicranium and thinning of the temporal bone are encountered in some space-occupying processes, of neoplastic, or parasitic origin, in subdural hygromas, in infantile encephalopathies, etc., and always require supplementary investigations for their discovery and adequate surgical solution. In hygromas, there is a scarcity of neurological signs, and a slightly delayed psychical development may be the only clinical symptom associated with the cranial deformity. The present case-association of a calcified interhemispheric cerebral haematoma and a subdural hygroma occupying almost half the hemisphere-is extremely rare. It represents two evolutive aspects of an intracranial blood effusion, following upon a forgotten skull injury, at birth or during early childhood.
