摘要
We report a rare case of central neurogenic hyperventilation (CNH) and hyperlactatemia after resection of a fourth ventricle tumor. Our management consisted of close monitoring and exclusion of alternate causes of hyperventilation and hyperlactatemia. We hypothesize that a localized increase in tissue lactate, related to tumor metabolism, may have triggered CNH in our patient through stimulation of the brainstem respiratory centers. CNH should be considered during the differential diagnosis of perioperative hyperventilation with respiratory alkalosis in patients with posterior fossa tumors. Hyperlactatemia can trigger compensatory hyperventilation but will not result in alkalosis.
