As seen in this patient with a typical appearance and location of an intraventricular meningioma, which appears as a relatively hyperdense lesion on CT scan and on MRI, it appears solid, iso to hypointense on T1 and T2 sequences, with vivid homogeneous post-contrast enhancement, a confident diagnosis was given.

The neurological consultation reached a consensus decision to follow up on this patient for a longer term and evaluate the development of obstructive hydrocephalus, progression of perilesional edema, or significant growth in tumor size. If the appearance remains stable under close surveillance, no surgical intervention is warranted.
