Papillary Ependymoma WHO Grade II of the Aqueduct Treated by Endoscopic Tumor Resection

الملخص EN

Papillary ependymoma is a rare tumor that may be located along the ventricular walls or within the spinal cord.

We report the case of a 54-year-old patient with a papillary ependymoma WHO grade II arising at the entrance of the aqueduct.

The tumor caused hydrocephalus.

The tumor was completely removed via a right-sided endoscopic approach with restoration of the aqueduct.

The free cerebrospinal fluid passage through the aqueduct was not only visualized by endoscopy but also controlled by intraoperative high-field magnetic resonance imaging.

Therefore, an additional endoscopic third ventriculostomy was unneccessary.
