title: "Brain on fire": a new imaging sign.
abstract: Primary central nervous system (CNS) marginal zone B cell lymphoma is a rare condition. It has an indolent disease course and usually presents as a dural-based lesion. We present a patient with non-dural-based, primary CNS marginal zone B cell lymphoma with an unusual imaging appearance, not previously described to our knowledge.
