Clinical Report

Low-grade Glioma (DNET)

Dr. John Honeycutt, Medical Director, Neuro-Trauma
Cook Children’s Medical Center Fort Worth, Texas

PATIENT INFO: 7 year-old male with new onset of seizures emanating from right temporal lobe. MRI showed large temporal lobe lesion.

SUMMARY: At time of surgery, tumor was easily identified but tumor tissue was very similar to brain tissue. Two intraoperative scans were performed, both showing residual tumor. Resection continued after both scans. The postoperative result was gross total removal of a low grade glioma. Patient had complication of loculated ventricle and had endoscopic fenestration of the ventricle several months later. Two years after surgery, patient was normal and off medication with no seizures and no residual tumor.
Total resection of the tumor at one time would not have been possible without iMRI, and would have required several surgeries to accomplish similar results. iMRI provided immediate feedback to verify that the lesion was entirely removed.
