Trapped temporal horn is a rare disorder with an isolated dilatation of the temporal horn secondary to obstruction of cerebrospinal fluid (CSF) flow at the atrium. The etiology may be both congenital and acquired. 1 These patients remain asymptomatic for a long time, but continuous ventricular enlargement produces raised intracranial pressure symptoms, visual field defects, hemiparesis, memory disturbances, and altered mentation. 2 Symptomatic patients require CSF diversion. Endoscopic ventriculocisternostomy is a physiological procedure like endoscopic third ventriculostomy. 3 It avoids shunt-related complications. We managed a case of a 7-year-old boy with a congenital trapped temporal horn. The pathology, radiological features, and management options are discussed. The patient's relative consented to the endoscopic ventriculocisternostomy. A fenestration was made in the tenia fimbria to communicate the temporal horn with the ambient cistern. 4 The visual impression of the ventricular anatomy appears different from the microscopic anatomic description in cadavers. 5 A thorough understanding of endoscopic ventricular anatomy is essential to perform such endoscopic procedures safely. The literature lacks an elaboration of ventricular anatomy from an endoscopic perspective. [6][7][8] We have described the correlation between microscopic and endoscopic anatomy and the surgical procedure. After surgery, the patient improved clinically, and at 4-month follow-up, he was doing well with stable ventricle size. The CSF flow across the fenestration can be visualized by cine phasecontrast MRI, which was also seen in the present case. 9 Images throughout the video from Rhoton, 5 modified with permission from the Congress of Neurological Surgeons.

“…1 Traditional approaches to SVS include endoscopic third ventriculostomy (ETV), change in shunt hardware, and even cranial vault expansion. [2][3][4][5] In this article, "Extra-Axial Third Ventriculostomy for the Treatment of Slit Ventricle Syndrome: 2-Dimensional Operative Video", 6 the authors describe an alternative approach to slit ventricle syndrome, using a minimal-access craniotomy for third ventriculostomy through fenestration of the lamina terminalis from a subfrontal approach. The authors demonstrate the efficacy of their approach in this small series (14 patients) with limited follow-up.…”
