Clear cell ependymoma with an atypical localisation mimicking intracranial glial tumour: A case report

Introduction
Ependymomas are tumours of the central nervous system, originating from the ependymal cells which line the ventricles and the central canal of the spinal cord. Less than one-third of all ependymomas are located supratentorially, most of the time in close proximity to the ventricle walls around the trigone area.
Case
34 year-old patient came into the outpatient clinic with headache and seizure. After radiological examination, she was operated on for an extra axial lesion located next to the left frontal gyrus. Pathological examination revealed a clear-cell ependymoma, WHO grade II, after which follow-up without any additional therapy was decided since the patient was young and total resection had been achieved.
Conclusion
Because of low incidence, radiological diagnosis is difficult. Even if total resection has been achieved, long term follow-up should be planned because of high rates of recurrence.
