Bilateral extradural hematoma formation following excision of a thoracic intradural lesion.

The authors report an unusual case of a 15-year-old girl who previously underwent resection of a posterior fossa medulloblastoma, and later underwent resection of a thoracic extramedullary metastatic lesion. Her consciousness deteriorated hours after removal of her spinal metastasis. A CT head scan identified bilateral extradural cranial hematomas, which were evacuated. To the authors' knowledge, this is the first report of a patient developing bilateral acute cranial extradural hematomas following excision of a thoracic intradural lesion.
