Bilateral chronic subdural hematomas without communication between the hematoma cavities: treatment with unilateral...

Communication between bilateral subdural hematoma cavities was not demonstrated by metrizamide computed tomography subdurography in three patients with bilateral chronic subdural hematomas. Because unilateral subdural tapping yielded a slack fontanel without untoward neurological findings, patients were treated by the placement of unilateral subdural-peritoneal shunts, resulting in resolution of the bilateral hematomas.
