(A) Pretreatment cranial MRI in sagittal section. There was a 4.5 x 2.4 x 2.2 cm mixed signal predominantly isointense lobulated mass in the left frontal lobe parasagittal region extending across the midline with involvement of the anterior corpus callosum to the right frontal lobe (thick arrow). The mass encroached into the left frontal horn and anterior third ventricle. Mixed signal lesions were also seen in the pineal gland about 3.3 x 2.4 x 2.2 cm and in the suprasellar region measuring about 1.7 x 0.9 cm (thin arrow). There was also moderate non-communicating hydrocephalus. (B) Postreatment cranial MRI in sagittal section showing tumor size reduction (1.6 x 0.8 cm) in the frontal lobe and resolution of suprasellar and pineal masses.

After three cycles of chemotherapy, repeat cranial MRI (Figure 1B) showed interval regression of the frontal mass which measured 1.6 x 0.8 cm from 4.5 x 2.4 cm.
