title: Calcified chronic subdural hematoma with intracerebral rupture forming a subcortical hematoma. A case report.
abstract: We report a calcified chronic subdural hematoma which ruptured intracerebrally forming an acute subcortical hematoma in the frontal lobe in a 59-year-old woman with long-standing liver cirrhosis. Both hematoma cavities communicated each other through a small defect within the inner membrane of the subdural hematoma. The content of both hematomas was identical and was of a clay-like clot. The inner membrane around this communication consisted of thick, very vascular granulation tissue with many hemosiderin deposits and was tightly adherent to the cortex. We speculated that a fresh bleeding into the granulation tissue resulted in formation of a subcortical hematoma through a rupture of the inner membrane. Disseminated intravascular coagulation likely played an important role in this unusual condition.
