A CT scan of the brain to rule out stroke surprisingly showed three round lesions, slightly hyperdense, with intra-axial and periventricular location (Fig. 1).
Brain MRI lesions showing: A, hypodensity on T1-weighted images. B, isodensity on T2-weighted images. C, enhancement after gadolinium administration.

T1-weighted images, isodensity on T2-weighted images, and enhancement after gadolinium administration (Fig. 2). These features were felt to be compatible with a primary lymphoma of the central nervous system (PLCNS).
