Presentation, surgical outcome, and supplementary motor area syndrome risk of posterior superior frontal gyrus tumors.

ABSTRACT:

Objective

Following resection of posterior superior frontal gyrus (PSFG) tumors, patients can experience supplementary motor area (SMA) syndrome consisting of contralateral hemiapraxia and/or speech apraxia. Given the heterogeneity of PSFG tumors, the authors sought to determine the risk of postoperative deficits and assess predictors of outcomes for all intraparenchymal PSFG tumors undergoing surgery (biopsy or resection), regardless of histology.

Methods

This was a retrospective single-center cohort study of adult PSFG-region tumors undergoing biopsy or resection by a single surgeon.

Results

A total of 106 consecutive patients undergoing 123 procedures (21 biopsies, 102 resections) fulfilled inclusion and exclusion criteria. Anaplastic astrocytomas were the most fre
