Hemangioblastomatosis represents an unusual and malignant leptomeningeal dissemination of hemangioblastoma (HB). It has been reported in patients with sporadic HB or von Hippel-Lindau (VHL) disease. Hemangioblastomatosis had been reported following resection of a primary HB lesion in all cases except one patient with a sporadic HB. We present a patient with VHL with several HBs at the brainstem, cerebellum, pituitary stalk and retina who developed spinal hemangioblastomatosis without previous craniospinal surgery. A whole spine MRI showed the spinal dissemination from the primary lesions. The patient received craniospinal radiotherapy due to the extensive spinal leptomeningeal dissemination and multiple HBs. MRI performed 12 months after the radiotherapy showed stability of the lesions.
