Asymptomatic calcified chronic subdural hematoma in the elderly.

A 77-year-old man with an asymptomatic calcified chronic subdural hematoma is reported. Thirty seven years elapsed between the time of the head trauma and diagnosis. The advanced age of the pa tient when the calcified chronic subdural hematoma was diagnosed and the long interval between the trauma and diagnosis were both unusual features of this case. As far as we know, this patient is the oldest reported in the literature. Removal of calcified chronic subdural hematoma in the elderly is neither necessary nor beneficial.
