MR – Axial and coronal T2 and postgadolinium FSPGR images show a solid and cystic enhancing left temporal lobe mass.


Ganglioglioma is a slow growing low grade neoplasm. Approximately 80% occur in children and young adults, with a peak between 10 and 20 years. The temporal lobe is the most common location and often associated with seizure.

Gangliogliomas may be different in children compared to adults. Lesions are up to 8 times larger in children; this may be related to higher mitotic indices, more compliant skull (patent sutures), or location. Cystic change is more common in children.

Lesions are typically iso- to hyperintense on T1, hyperintense on T2 and show variable enhancement. Calcifications are present in 35%.
