Primary Cranial Vault Lymphoma with Extra- and Intracranial Extension: A Case Report

Primary cranial vault lymphoma with extra- and intracranial extension in an immunocompetent patient is extremely rare. Given its rarity, the optimal management of this entity remains uncertain. We report an atypical case of a 21-year old immunocompetent man, who presented with an 8-month history of enlarging parieto-occipital mass. CT and MR imaging revealed a large mass with extra cranial and cranial components with sagittal sinus involvement. Unusually, angiography showed a significant tumor blush with large feeding vessels. After a pre surgical embolization, the patient underwent a complete tumor resection followed by radio and chemotherapy with satisfactory results.
