case_images: (a) Axial magnetic resonance imaging (MRI) with contrast showing tumor extending from anterior fossa to intraventricular space. (b) Axial MRI with fluid-attenuated inversion recovery sequence showing the significant perilesional edema.

case_images: Sagittal magnetic resonance imaging with contrast showing a large mass centered on the left side of anterior cranial fossa/anterior falx with invasion of the skull base, medial left orbit, and left frontal sinus. There was notable erosion of the lamina papyracea on the left with extensive regional mass effect and effacement of the bilateral frontal horns and possible entrapment/developing hydrocephalus of the right occipital horn.

case_images: (a) Surgical photo from pericranial graft already sutured to available dura of the skull base and fat graft harvested. The defect of the transbasal approach is evident. (b) Illustration of the surgical reconstruction.
