Venous congestive myelopathy of the cervical spinal cord: an autopsy case showing a rapidly progressive clinical course.
We report a rapidly progressive myelopathy in a 74-year-old Japanese man who was admitted to our hospital with a 4-month history of progressive gait disturbance and died of pneumonia followed by respiratory failure on the 22nd day of admission. During the course of his illness, magnetic resonance imaging (MRI) revealed intramedullary lesions with edematous swelling from the medulla oblongata to the spinal cord at the level of the fourth vertebra. After administration of contrast medium, the ventral portion of the lesion was mildly and irregularly enhanced and a dilated vessel was recognized along the ventral surface of the upper cervical cord. At autopsy, ischemic changes were observed in the upper-to-middle cervical cord segments, with so-called arterialized veins in the subarachnoid space. No neoplastic lesions were found within or outside the brain and spinal cord. These pathological findings were essentially those of venous congestive myelopathy (VCM) associated with dural arteriovenous fistulae (AVF), formerly known as Foix-Alajouanine syndrome. VCM associated with dural AVF, which is now considered to be treatable in the early stages, is rare found in the cervical spinal cord. The present autopsy case, with MRI findings, provides further information that might be useful for recognition and diagnosis.
