Insights

This study reports a rare case of an ependymal cyst in the cerebellopontine angle, a location more commonly associated with arachnoid cysts. The findings highlight the importance of considering ependymal cysts in this anatomical region.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pathology

Background:

  • Ependymal cysts are typically found intracerebrally or in the subarachnoid space.
  • The cerebellopontine angle is a frequent location for arachnoid cysts but rarely for ependymal cysts.

Observation:

  • A case of a large ependymal cyst in the left cerebellopontine angle is presented.
  • A 12-year-old girl presented with left-sided hearing disturbance.
  • Imaging (CT and MRI) identified a cystic lesion in the left cerebellopontine angle.

Findings:

  • Surgical exploration revealed a discrete, thin-walled cyst.
  • The cyst originated from the choroid plexus of the lateral foramen of Luschka.
  • The ependymal cyst was confirmed histopathologically and had no connection to the arachnoid.

Implications:

  • This case underscores the rarity of ependymal cysts in the cerebellopontine angle.
  • Accurate diagnosis and surgical management are crucial for patients with cerebellopontine angle cysts.
  • Further research may elucidate the specific origins and behaviors of ependymal cysts in this location.
