Abstract
BACKGROUND: Peri-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 PRESENTATION: We 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. CONCLUSION: Elevation in serum lactate level during a large meningioma resection could be transient and may not result in morbidity.
