Radiological Appearances of Primary Central Nervous System Lymphoma (PCNSL)

Category: JMSR Oncology


Primary central nervous system lymphomas (PCNSL) are uncommon tumours, accounting for only 2% of primary brain tumors. Recently many investigators have showed interest in MRI characteristics for aiding in diagnosis and stratify prognosis.

In this article, we aimed to review characteristic findings on traditional and advanced Imaging seen in immune competent patients with intracranial primary CNS lymphoma (PCNSL).

CT scan and MRI examinations of 15 immunocompetent patients with biopsy-proven PCNSL were retrospectively evaluated. T1 and T2 signal characteristics as well as contrast enhancement features are described in all patients. Diffusion, perfusion and proton-MR-spectroscopy features are described in a subset of these patients.
