case_images: Magnetic resonance imaging brain - (a) T1 axial sequence, (b) T2 axial sequence, (c) T1 C+ axial sequence, (d) T1 C+ coronal sequence, (e) T2 sagittal sequence, and (f) T1 C+ sagittal sequence - showing a T1 hypointense, T2 iso-hyperintense axial lesion in the right frontal region with heterogeneous enhancement with prominent peritumoral vasogenic edema with extension into extracalvarial space and another similar lesion in the posterior fossa.

case_images: T1 hypointense, T2 isohyperintense axial lesion in the right frontal region with heterogeneous enhancement and prominent peritumoral vasogenic edema with hyperostosis of overlying bone and extension into extracranial space [Figures 1 and 2]. There was another lesion in the posterior fossa.
case_images: Contrast-enhanced computed tomography head - (a and b) axial cuts - showing contrast-enhancing lesion in the right frontal region with extension into extra calvarial space with perilesional edema and another similar lesion in the posterior fossa with mass effect.

case_images: T1 hypointense, T2 isohyperintense axial lesion in the right frontal region with heterogeneous enhancement and prominent peritumoral vasogenic edema with hyperostosis of overlying bone and extension into extracranial space [Figures 1 and 2]. There was another lesion in the posterior fossa.
case_images: Postoperative computed tomography head - (a and b) (a) axial cuts - showing tumor decompression of the right frontal lesion and (b) tumor decompression of posterior fossa lesion with posterior fossa decompression.

case_images: Gross total tumor excision could be achieved [Figure 3a]. She also underwent excision of the tumor in the posterior fossa, as the posterior fossa tumor had increased significantly in size [Figure 3b].
