Bilateral symmetrical enhancing brainstem lesions: an unusual presentation of primary CNS lymphoma

European Journal of Neurology (impact factor: 3.69). 10/1999; 6(6):721 - 723. DOI:10.1046/j.1468-1331.1999.660721.x

ABSTRACT We report a patient with a progressive brainstem syndrome, who on magnetic resonance imaging had large bilateral, symmetrical, contrast-enhancing, infratentorial space-occupying lesons. Biopsy of one of the lesions revealed this unusual appearance to be due to a primary central nervous system (CNS) lymphoma of B-cell type. Symmetry of lesions may be a clue to the diagnosis, perhaps reflecting the mechanism by which CNS lymphomas spread.
