. Contrast-enhanced MR imaging is the method of choice for detecting CNS lymphoma. Primary Central Nervous System Lymphoma PCNSL is a rare neoplasm that can involve brain eye leptomeninges and rarely spinal cord. Nearly all lesions show homogeneous enhancement with contrast material Fig.

PCNSL lesions most typically enhance homogeneously on T1-weighted magnetic resonance imaging MRI and appear T2-hypointense but high variability in MRI features is commonly encountered. In leptomeningeal CNS lymphoma representing two-thirds of secondary CNS lymphomas imaging typically shows leptomeningeal subependymal dural or. Contrast-enhanced MR imaging is the method of choice for detecting CNS lymphoma.

In leptomeningeal CNS lymphoma representing two-thirds of secondary CNS lymphomas imaging typically shows leptomeningeal subependymal dural or cranial nerve enhancement. On MRI B-cell primary CNS lymphoma lesions are clearly delineated masses that appear isointense to hypointense on T1-weighted images and mostly hypointense on T2-weighted images 1 2 Fig.
