Case contributed by Dr Lemuel Marquez Narcise

Presentation

Paediatric patient presenting with headache. The patient is afebrile and does not have any other neurologic or visual deficits.

Patient Data

Age: 10
Gender: Female
MRI

Selected MRI sequences show a well-defined round mass centered within the trigone of the left lateral ventricle.  The mass is isointense to gray matter on T1 and T2-weighted images, and exhibits homogeneous enhancement.  Perilesional white matter edema and obstructive hydrocephalus are seen.

Case Discussion

Meningioma is the most common extra-axial neoplasm of adults and accounts for 15% of all intracranial neoplasms.  It is second to gliomas in overall prevalence.  Meningiomas are most frequently seen in convexity and parasagittal locations.  In children, the most common site is the ventricles.
