Medial Tentorial Dural Arteriovenous Fistulae Embolization: Single Experience With Embolic Liquid Polymer Squid And Review Of The Literature.
Tentorial dural arteriovenous fistulas (DAVFs) are uncommon, complex fistulas located between the leaves of the tentorium cerebelli with a specific anatomic and clinical presentation characterized by high hemorrhagic risk. We present a rare case of a medial tentorial DAVF successfully managed via transarterial embolization using SQUID liquid polymer. ⋯ Medial tentorial DAVFs are considered the most complex DAVFs because of their location and extensive vascular supply. Our literature review focused on endovascular treatment of tentorial DAVFs to highlight the usefulness of new embolic agents in management of these diseases. To our knowledge, we report the first successful use of SQUID liquid polymer in management of a tentorial DAVF.

Rosette-Forming Glioneuronal Tumor of the Fourth Ventricle in Children: Case Report and Literature Review.
Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle is a rare World Health Organization (WHO) grade I neoplasm. Gross total resection (GTR) is the treatment of choice, and there is no firm evidence supporting other treatment options when GTR is not feasible. ⋯ We report a case of chemotherapy administration as a first-line treatment for a subtotally resected RGNT. Chemotherapy may be considered as an adjuvant therapy option for RGNT when GTR cannot be achieved. Furthermore, increased incidence of recurrence in the pediatric population may suggest that the tumor biology of RGNT in children differs from that in adults.

Recovery of oculomotor nerve palsy after microsurgical and endovascular treatment has been studied in numerous small series of predominantly ruptured aneurysms. Little consideration has been given to the distinction between ruptured and unruptured aneurysms. This study examines the influence of treatment modality on oculomotor palsy recovery as a result of unruptured posterior communicating artery aneurysms. ⋯ In this narrative review, surgical clipping of unruptured posterior communicating artery aneurysms was associated with a higher rate of associated oculomotor palsy recovery than was endovascular treatment.

Endoscopic Third Ventriculostomy in Patients with Neurofibromatosis Type I: A Multicenter International Experience.
Hydrocephalus in patients with neurofibromatosis (NF) type 1 is usually obstructive and may arise secondary to tumoral or nontumoral causes. Treatment of hydrocephalus in these patients is often challenging owing to combined pathologies and unique anatomic changes. The use of endoscopic third ventriculostomy (ETV) as treatment has rarely been described in this group. We aimed to characterize indications, considerations, and outcome of ETV in patients with NF 1 gathered in a multicenter international cohort. ⋯ ETV is a safe treatment for selected patients with NF 1 and obstructive hydrocephalus. Individual anatomic and pathologic aspects should be taken into consideration.

To accurately describe patient characteristics and the clinical presentation of fatal colloid cysts. ⋯ Our data suggests that the prodrome preceding sudden death in the setting of a colloid cyst may be shorter in adults. Also, most fatal colloid cysts measured 1 cm or larger.
