Imaging of a thoracic spinal nerve haemangioblastoma by three-dimensional digital angiography.

Haemangioblastomas occur sporadically or in association with Von Hippel-Lindau (VHL) disease. Occasionally, they are associated with intrathecal cauda equina nerve roots and rarely with spinal nerve roots. The occurrence of a completely extrathecal, thoracic spinal nerve haemangioblastoma is exceptional, with only one case previously described in the English-language literature. We report an extradural thoracic spinal nerve haemangioblastoma in a patient with VHL disease causing a progressive thoracic radiculopathy. The advantages of three-dimensional digital angiography will be discussed. Three-dimensional reconstruction of the images acquired by rotational digital subtraction angiography is one of the most promising developments to improve surgical planning for complex vascular lesions.
