High serum lactate level in cranial meningioma resection: A case report

•Peri-operative elevated serum lactate could be a sign of high risk of morbidity among affected patients.•The rise in serum lactate level can be associated with metabolic acidosis in patient with systemic hypo-perfusion.•Elevation in serum lactate level during a large meningioma resection could be transient and may not result in morbidity.

BackgroundPeri-operative elevated serum lactate could be a sign of high risk of morbidity among affected patients. However, this finding can be self-limiting and with no consequences in some conditions.Case presentationWe present a case of transient elevated serum lactate level in a 33 year old man that underwent a cranial meningioma resection. The patient had an elevation of serum lactate levels peri-operatively, with a spontaneous gradual decline in the serum lactate five hours post-operatively. The patient had an otherwise uncomplicated post-operative course and was discharged home on the fifth post-operative day.ConclusionElevation in serum lactate level during a large meningioma resection could be transient and may not result in morbidity.
