Abstract
Skull base meningiomas may present as clinically aggressive tumors despite being histologically benign. Here we describe a clinico-radiological entity of diffuse midline skull base meningiomas responsible for several neurological morbidities, including hearing and vision loss, intracranial hypertension, secondary hydrocephalus and tonsillar herniation with spinal cord compression. Surgery and radiotherapy were ineffective in stopping the clinical course of those tumors. After targeted sequencing of known mutated genes in meningiomas, we discovered TRAF7 mutations in two out of four tumors, stressing the importance of focusing the research efforts of the meningioma community in understanding the mechanisms underlying TRAF7 related meningioma tumorigenesis.
