• An awake patient presented with central neurogenic hyperventilation induced by a cerebral tumor. Corticosteroid therapy and brain irradiation while the patient was anesthetized and respiration controlled under pancuronium-induced respiratory paralysis were followed by tumor regression and resolution of hyperventilation. Recurrence of tumor 6 weeks later was not accompanied by recurrence of hyperventilation. Cytologic study of cerebrospinal fluid revealed B-cell lymphoma. This patient brings to 10 the number of cases recorded with tumor-induced central neurogenic hyperventilation. Five of the eight patients with known tumor histology had a primary cerebral lymphoma, a rare neoplasm that comprises only 1% of all intracranial neoplasms. The disproportionately high frequency of central neurogenic hyperventilation in patients with cerebral lymphoma has therapeutic implications that are briefly reviewed.
