Hemangioblastomas are benign vascular tumors that can occur throughout the central nervous system (CNS) sporadically or in association with von Hippel-Lindau (VHL) disease. We present a case of an 11-year-old girl with a hemangioblastoma that tested negative for germline mutation of VHL disease at the time of diagnosis. Our patient went on to have multiple recurrences and further areas of concern for disease within the CNS. Repeat VHL testing was pursued many years later and remained negative for germline mutations. However, next-generation sequencing (NGS) testing on prior tumor tissue returned positive for VHL somatic mutations. The diagnosis of VHL mosaicism has important implications on management and risk of recurrence of hemangioblastoma, along with the need for close follow-up with surveillance imaging.
