Occipital lobe ependymal cyst with unusual presentation

Abstract

Intraparenchymal cysts without communication to the ventricles or the subarachnoid space are named ependymal or epithelial cysts. The estimated ratio of their incidence compared with arachnoid cysts is 1:10. Neurologic defi cit can occur when the cyst exerts mass effect on its surroundings. We report a case of cerebral ependymal cyst in a 75-year-old lady who presented with history of headache, vomiting and left incomplete homonymous hemianopsia. Neuroimaging studies showed a large right occipital cyst. She underwent the neurosurgical procedure of marsupialization. Histologic fi ndings and the immunophenotype was consistent with a diagnosis of ependymal cyst. The patient made an excellent recovery after the procedure.

Unusual presentation of a neuroepithelial cyst: A case report

“…The profound literature has described this mass as an ependymal cyst, neuroepithelial cyst, glioependymal cyst, and neuroglial cyst. These descriptors indicate the complexity of this disease's terminology [5 , 6] . We illustrate a case of neuroglial cyst with accompanying visual and movement disturbances.…”
