Acute interdural hematoma mimicking epidural hematoma: a case report.
Intracranial hematoma rarely presents between two dural layers of pachimeninges.     Here, we present a case of an interdural hematoma with similar appearance to an     epidural hematoma. A 51-year-old man presented with a left temporal contusion     following a motor vehicle accident. After craniotomy and contusion removal, the     post-operative CT scan showed a parietal intracranial hematoma located posterior     and superior to the bone flap. The CT scan appearance of the new hematoma was     similar to the CT scan appearance of an epidural hematoma. Upon operation, we     determined that the hematoma was located between two layers of dura mater, i.e.,     an interdural hematoma. We removed the hematoma and sutured the two layers of     dura to each other at multiple sites. Interdural hematoma is a rare entity. Its     appearance in a CT scan can be mistaken for an extradural hematoma.
