Severe course of radiation-induced meningioma — a new insight in screening for patients after radiotherapy?

Meningiomas, being mostly benign tumours, are derived from the arachnoid cap cells. Their etiopathogenesis is based on various factors, including past radiation. The presented case of a 25-year-old patient, who developed a radiation-induced superior sagittal sinus meningioma based on his past head radiation distributed during acute lymphocytic leukaemia. The tumour’s clinical image presented at first as headache, nausea, and dizziness, computer tomography and subsequently MRI were performed. The imaging examination revealed a very extensive, contrast-enhanced tumour mass located centrally on both sides and within the superior sagittal sinus. With the most likely diagnosis of parasagittal meningioma, the patient was qualified for tumour excision. The surgery was performed successfully resulting in maximal safe subtotal resection. After the surgery, the patient developed complications including hydrocephalus, which resulted in 5-months long hospitalization. The presented case illustrated the need for increased clinical attention in patients threatened by radiation (including radiotherapy), focused on possible head lesions
