The patient was transferred to another institution for eventual neurosurgery, where she first underwent MRI brain (study not available) on the same day as the CT head.
MRI report
Left temporal intra-axial cystic lesion with a solid enhancing component and mild perilesional edema. The lesion compresses the temporal horn of the left ventricle and bulges into the ventricle. Highly suspicious for high-grade glioma.
Enhancing extra-axial lesion on the floor of the right middle fossa, involving Meckel's cave and right cavernous sinus, and entering the foramen ovale. No narrowing of ipsilateral cavernous carotid. Differential diagnosis includes meningioma, granulomatous lesion, IgG4-related mass, lymphoproliferative process.
A small hyperintense lesion in the body of the left ventricle, with no diffusion restriction of enhancement. Its nature is not clear, possibly subependymoma.
