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 deficit 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 findings and the immunophenotype was consistent with a diagnosis of ependymal cyst.
The patient made an excellent recovery after the procedure.
