We describe a case of 36-year-old man who presented with a subacute headache preceded by a 1-month history of posterior neck pain without trauma history. Head and neck magnetic resonance imaging (MRI) studies disclosed bilateral supratentorial subdural and retroclival extradural hematomas associated with marked cervical epidural venous engorgement. Cerebral and spinal angiography disclosed no abnormalities except dilated cervical epidural veins. We performed serial follow-up MRI studied to monitor his condition. Patient's symptoms improved gradually. Serial radiologic studies revealed gradual resolution of pathologic findings. A 3-month follow-up MRI study of the brain and cervical spine revealed complete resolution of the retroclival extradural hematoma, disappearance of the cervical epidural venous engorgement, and partial resolution of the bilateral supratentorial subdural hematoma. Complete resolution of the bilateral supratentorial subdural hematoma was confirmed on a 5-month follow-up brain MRI. The diagnosis and possible mechanisms of this rare association are discussed.

A 43-year-old woman presented with dizziness, ataxia and right hearing difficulty. Her magnetic resonance images demonstrated an inhomogeneously contrast-enhanced large tumor growing into right cavernous sinus and Meckel's cave located totally within intradural retroclival region. She underwent retromastoid suboccipital craniotomy to resect the tumor mass and adjuvant gamma knife radiosurgery for remnant tumor at 1 month after operation. Adjuvant radiosurgery after surgical excision seems to be effective for the treatment of intradural extraosseous chordomas.

Most chordomas show extradural extension and bone destruction. A 32-year-old man presented with neck pain and progressive paraparesis. He had been diagnosed a clival chordoma and underwent an operation seven years ago. Radiological studies revealed that the tumor was recurred in a retroclival area and invaded into intradural region. We removed the tumor by two staged operations. After surgery, satisfactory results were achieved.
