Magnetic resonance imaging (MRI) of the brain indicated abnormal enhancement along the ependymal margin of the frontal horns of the bilateral lateral ventricles with four distinct abnormal enhancing mass lesions in the hypothalamus (11 x 12 x 13 mm), pineal gland (8 x 8 x 9 mm), the trigon of the right lateral ventricle (5 x 5 x 4 mm), and the foramen of Magendie (7 x 6 x 9 mm) which demonstrated restriction diffusion indicating hypercellularity (Figure 1).
