Meningioma Induced by Radiotherapy and a Silicone Foreign Body – Case Report and Literature Review
Background: Meningiomas are the most common radiotherapy related brain tumors, their development can also be induced by intracranial foreign bodies like intraventricular drains in mechanism of chronic intracranial inflammation. The authors present casuistic case of intracranial meningioma developed in contact with a silicone intraventricular in patient who had also brain radiotherapy in childhood. In references, there are only two descriptions about meningiomas induced by both radiotherapy and a silicone foreign body.
Case presentation: 30-year-old patient with intracranial meningioma was admitted to neurosurgical department with hemiparesis and severe headaches. Shunt was placed 15 years earlier due to hydrocephalus and the patient had also brain radiation therapy at that time. The neurosurgical tumor removal (Simpson I) was achieved by authors. Shunt was removed during tumor resection but it had to be placed again after few days due to hydrocephalus. During ten years follow-up no tumor recurrence was observed and it can be assessed that the prognosis is favorable.
Conclusions: Combination of these two factors is extremely rare however such case can be significant advice for oncological patients with shunts systems who had undergone brain radiotherapy.
