Radiology Cases of Desmoplastic Infantile Ganglioglioma

CT and MRI of desmoplastic infantile glioma — Axial (above left) and coronal (above right) CT without contrast of the brain show a mass in the left temporal lobe that medially has a higher density solid component and laterally has a lower density cystic component. The mass is surrounded by low density vasogenic edema and is causing some midline shift to the right. Axial (below left) and coronal (below right) T1 MRI with contrast of the brain show homogenous contrast enhancement of the solid portion of the mass.
