title: Intravascular lymphoma presenting as an orbital mass lesion: a case report.
abstract: We describe a case of intravascular lymphoma that presented as an orbital mass lesion. A 77-year-old female presented with longstanding fatigue and one-month of diplopia. Magnetic resonance imaging (MRI) revealed a frontal lobe brain lesion and a right orbital mass. Brain biopsy was interpreted as anaplastic oligodendroglioma. Orbital biopsy revealed intravascular lymphoma. On review of brain histopathology, the diagnosis was revised to CNS intravascular lymphoma. To the best of our knowledge, this case represents the first report of intravascular lymphoma presenting as an orbital mass lesion.
