Large tentorium meningioma causing chiari malformation type-1 with syringomalia with complete resolution of syrinx and chiari after surgical excision: rare case report with review of literature

Abstract

Abstract A 35-year-old female was admitted with a 3-year history of headache, gait disturbance and vertigo on & off and one year history of nasal regurgitation. Magnetic resonance imaging demonstrated a large tentorium meningioma left sided and syringomyelia in the upper cervical cord associated with caudal displacement of the cerebellar tonsil (chiari type -1 malformation). Herniation of the cerebellar tonsil and distortion of the brain stem had probably caused disturbance of cerebrospinal fluid flow which combined with obstruction of the spinal canal, caused the syrinx. Complete excision of the tumor resulted in symptomatic improvement of these symptoms with complete resolution of syrinx & chiari.
