Primary diffuse large B cell lymphoma of the cranial vault.

Primary diffuse large B cell lymphoma of the cranial vault.

Primary non-Hodgkin's lymphoma of the cranial vault is extremely rare. This case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. Initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. Biopsy revealed a diagnosis of diffuse large B cell lymphoma (DLBCL). A thorough work-up revealed no other point of involvement. This case is concerned about considering lymphoma in the differential diagnosis of calvarial lesions with both intra- and extra cranial extensions but without obvious intervening bony destruction.
