Microsurgical Resection of the IV Ventricle Subependymoma: 2-Dimensional Operative Video

A medical publication by Dr. Kenan Arnautovic and Dr. Frederick Boop


In this video, we demonstrate microsurgical resection of IV ventricle subependymoma. To the best of our knowledge, this is the first video case report of a microsurgical resection of subependymoma of the IV ventricle in the peer-reviewed English literature.

Subependymomas are benign central nervous system tumors, typically arising in ventricular spaces, mostly in the IV and lateral ventricles.1-3 They are isointense on T1 and hyperintense on T2-weighted magnetic resonance imaging (MRI) with minimal or no enhancement.4 Microsurgery remains the mainstay treatment. Complete tumor resection is possible and curative with excellent prognosis.1,5-7 Although the clinical course appears benign, the inability to diagnose them radiographically with certainty and the possibility of an alternative malignant lesion support a low threshold for early and …
