A 42-year-old male, HIV (human immunodeficiency virus) positive for 13 years, but without use of antiviral therapy, presented weight loss of 6 kg and erythematous-purplish lesions in the right buttock. Biopsy was showed cutaneous diffuse large B-cell lymphoma. The patient received antiretroviral therapy and six cycles of chemotherapy achieving complete remission.After 5 years, the patient presented progressive headache with an episode of loss of balance with fall and mental confusion. Brain magnetic resonance imaging (MRI) showed a mass lesion in the periventricular region, involving the splenium of the corpus callosum with restricted diffusion. The brain images were consistent with glioblastoma (GBM) or DLBCL (diffuse large B-cell lymphoma). The hypoperfusion of the lesion on MRI was of fundamental importance for the differential diagnosis, favouring the diagnosis of DLBCL.

Introduction and importance: Meningioma, also known as meningeal tumor, is a primary tumor of the central nervous system (CNS). Originates from arachnoid cap cells. Case presentation A 65-year-old female patient presented with hard, painless swelling in the right parieto-fronto-temporal region of the skull, which has been growing for the past 6 months. And computed tomography (CT) scans revealed a lytic lesion. The patient underwent a cranitotomy and Resection of tumor with safe margins were performed, after the operation, the patient was neurologically intact and the patient was discharged in stable condition after disappeared the symptoms. Discussion Extradural meningiomas make up a small percentage, approximately 1–2%, of all meningiomas, This type of mass comprise a small percentage of all meningiomas, with primary intraosseous meningiomas commonly found in frontotemporal orbits, anterior cranial fossa, paranasal sinuses, nasal cavity, neck, and petrous region of the temporal. Conclusion Here we present a case of primary intraosseous meningiomas although the origin of this tumor is not well understood, but usually present with the osteoblastic type or osteolytic lesion in rere case.
