Imaging Findings

A contrast-enhanced T1 image showed an enhancing mass located in the anterior third ventricle near the foramen of Monro (Figure 1). Endoscopic biopsy of the mass demonstrated histologic findings consistent with hemangiopericytoma. CT 5 months later demonstrated that the mass had grown (Figure 2).

Figure 1.

Contrast-enhanced T1 MRI shows an enhancing mass in the third ventricle near the foramen of Monro.

Figure 2.

Noncontrast CT 5 months later demonstrates interval enlargement growth of the mass. Postoperative subarachnoid hemorrhage resulted in hydrocephalus and need for shunt placement.
