The development of a calcified epidural hematoma after neurosurgery: A report of three cases

Abstract

We report 3 cases in which calcified epidural hematomas were found after neurosurgery and give the details below. Case 1 underwent ventriculo-arterial shunt at the age of 6 for congenital hydrocephalus. More than 10 years later, a calcified epidural hematoma on the left side and a calcified chronic subdural hematoma on the right were found. In case 2, a patient with holoprosencephaly and marked hydrocephalus, an acute epidural hematoma that had occurred after placement of a ventriculo peritoneal shunt was found to have calcified. Case 3, a patient who underwent surgery for an intraventricular glioma, developed a calcified epidural hematoma of the contralateral side to where a craniotomy had been performed more than 10 years earlier. The development of a calcified chronic subdural hematoma after decompressive intracranial surgery is a well known occurrence, but the fact that a calcified epidural hematoma can also develop after decompressive surgery should also be kept in mind and should receive due attention.
