A Case of Primary T-Cell Central Nervous System Lymphoma : MR Imaging and MR Spectroscopy Assessment

Abstract EN

Primary central nervous system lymphomas (PCNSLs) are mainly B-cells lymphomas.

A risk factor for the development of PCNSL is immunodeficiency, which includes congenital disorders, iatrogenic immunosuppression, and HIV.

The clinical course is rapidly fatal; these patients usually present signs of increased intracranial pressure, nausea, papilledema, vomiting, and neurological and neuropsychiatric symptoms.

PCNSL may have a characteristic appearance on CT and MR imaging.

DWI sequences and MR spectroscopy may help to differentiate CNS lymphomas from other brain lesions.

In this paper, we report a case of a 23-year-old man with T-primary central nervous system lymphoma presenting with a mass in the right frontotemporal lobe.

We describe clinical, CT, and MRI findings.

Diagnosis was confirmed by stereotactic biopsy of the lesion.
