Ventriculoperitoneal shunt related meningioma: a case report

Abstract

Abstract Meningiomas are the most common primary, non-glial tumours of the brain and spine, and represent the most common extra-axial lesions. The typical meningioma is a dural-based, markedly enhancing extraaxial mass; they exhibit cortical buckling with trapped cerebrospinal fluid clefts or cortical vessels. There are factors strongly associated with risk of developing meningioma, as in the case of exposure to ionizing radiation, or exogenous or endogenous hormones, as in this case, the presence of shunt material as a foreign body may have contributed to oncogenesis on the basis of a chronic inflammatory reaction. The aim of this report is to present the clinical case of a meningioma, which enveloped the proximal catheter of ventriculoperitoneal shunt valve
