Hemangioblastomas with leptomeningeal dissemination: case series and review of the literature

摘要

Leptomeningeal dissemination of hemangioblastomas (HB) of the central nervous system (CNS) is extremely rare. Few studies have reported leptomeningeal involvement in sporadic HB or in HB associated with von Hippel-Lindau syndrome. The clinical and radiological features of leptomeningeal involvement in HB after surgery have not been described in detail.
