  • Look Inside

We report a case of a 55-year-old man with endodermal cyst located in the cerebellopontine angle cis-tern. The patient presented with dizziness. Magnetic resonance imaging (MRI) revealed multilocular cysticlesion at the right cerebellopontine angle. Tl-weighted image showed a mass with a low signal intensity,but higher intensity than CSF. Gd-DTPA T1-weighted image showed no enhancement in the mass.Diffusion-weighted image showed a mass with no signal lesion. After successful surgical removal, it wasfound to be an endodermal cyst. These cysts have usually been found in the spinal canal, and their in-tracranial occurrence is exceptional. The unusual location of the cyst and its histological features andradiological findings are discussed.
