Magnetic resonance imaging (MRI) showed a well demarcated, 4 cm in diameter, heterogeneously enhancing mass in the right lateral ventricle trigone (Fig. 1).
Microscopic appearance of the tumor. a: Haematoxylin-eosin stain and b: immunohistochemistry for thyroglobulin demonstrate thyroid cancer metastasis.

On histological examination, the tumor demonstrated follicular structure containing colloidal substances (Fig. 2).
Gadolinium-enhanced magnetic resonance imaging (MRI) obtained 14 months later demonstrates necrosis of the tumor without growth.

The intraventricular mass gradually lost enhancement, and MRI obtained 14 months after surgery showed complete central necrosis with rim enhancement, with the patient remaining in stable neurologically (Fig. 3).
