A patient with multiple synchronous gliomas of distinctly different grades and correlative radiographic findings.
BACKGROUND
Multiple gliomas represent approximately 2 to 5% of all high-grade gliomas which are categorized as multifocal or multicentric depending on the timing, location and pattern of spread. We present a patient with bi-hemispheric, noncontiguous, low- and high-grade gliomas proven by biopsy. She underwent surgical excision and radiotherapy, but unfortunately succumbed to her disease shortly thereafter.


METHODS
A 64-year-old female presented to the hospital with confusion, disorientation and retrograde amnesia after an unwitnessed fall. There were no symptoms of headaches or visual disturbances before presentation. Magnetic resonance imaging (MRI) with and without gadolinium revealed a nonenhancing left temporal lobe mass without surrounding edema, an enhancing left frontal lobe mass with surrounding edema, and an enhancing right parietal lobe mass with surrounding edema. The patient underwent a left frontal craniotomy with gross total resection of the left frontal mass and a left temporal craniotomy, anterior temporal lobectomy and sub-total resection of the temporal lobe mass. Intraoperative Brainlab® image-guided navigation was used. Postoperative treatment consisted of radiotherapy.


CONCLUSIONS
This is the first reported case of multiple separate glial tumors, each with differing grades in which an MRI can be correlated with the tissue diagnoses. This case also highlights the possible mechanisms of transformation of glial tumors in the continuum from benign to malignant forms, lending insight to the possibility of using advanced genetic analysis in the treatment and diagnosis of these entities.
