Background: According to the classification of Congard et al., type V dAVFs
mainly drain into the spinal perimedullary veins. About half of the patients present
with myelopathy. We report a case with such a rare lesion and discuss its clinical,
radiological, as well as therapeutic aspects.
Case presentation: A 57y/o male came to visit our hospital with progressive
ascending myelopathy for one week. Cervical spine MRI revealed a high intensity
signal in the brain stem and upper cervical spinal cord on T2WI with some
serpentine abnormal vasculature. Digital subtraction angiography elucidated a
dural arteriovenous fistula that derived from a branch of an extracranial posterior
inferior cerebellar artery with perimedullary venous drainage. The patient was
referred to the neuroradiology department for embolization. Post-embolization
angiography showed complete obliteration of the dAVF, and the PICA was
preserved.
Conclusion: Early diagnosis and treatment of type V dAVF permit a better
prognosis. There are several treatment options for dAVF. Embolization may be the
treatment of choice and should be tried first because of its efficacy and safety. |
