A Rapidly Regrowing Benign Meningioma After Total Removal: Case Report

ABSTRACT

The average interval from first operation to recurrence is about 4 years and the reported shortest interval of malignant meningioma is about 6 months. The authors reported a case of rapidly regrowing benign meningioma, located on the outer 1/3 of the right sphenoid wing. The patient was free of recurrence only at 4 months after the first surgery in spite of macroscopic complete removal of the tumor. Factors associated with recurrence of meningioma are also discussed.
