[Primary central nervous system lymphoma presenting with central neurogenic hyperventilation. A case report and review of the literature].
BACKGROUND
Central neurogenic hyperventilation (CNH) in an awake patient is a rare entity.


METHODS
We report here a 54-year-old patient who developed central neurogenic hyperventilation as the initial presentation of a primary central nervous system lymphoma located in the brainstem.


CONCLUSIONS
The patient's hyperventilation resolved completely with chemotherapy for primary CNS lymphoma. Most of the cases reported in the literature are related to a diffuse tumor of the brainstem with an intriguing overrepresentation of primary CNS lymphoma. The pathogenesis of CNH is discussed.
