Cerebral Vasospasm after Posterior Fossa Tumor Surgery: A Case Report and Literature Review.

INTRODUCTION

This report presents an unusual case of symptomatic vasospasm following resection of posterior fossa tumor in a 9-year-old female patient. To the best of our knowledge, only 6 pediatric cases of vasospasms as a complication of brain tumor surgery have been reported in the literature previously.

CASE PRESENTATION

After an uneventful 12 days postoperatively, the patient suddenly presented with acute neurological deterioration on the 13th day and MR angiography showed bilateral narrowing of the supraclinoid segments of the internal carotid artery and the proximal parts of the A1 and M1 segments. Hypervolemia and vasospasm treatments were administered, and the patient exhibited no neurological deficit at the time of discharge, confirmed via normal MRI.

CONCLUSION

Early diagnosis and intervention in case of suspected symptomatic cerebral vasospasm after pediatric posterior fossa tumor surgery are essential in order to achieve favorable outcomes.
