Transventricular Endoscopic Management of a Suprasellar Arachnoid Cyst Causing Precocious Puberty

Suprasellar cysts arachnoid cysts (SSAC) are relatively uncommon making up less than 2% of all arachnoid cysts. Suprasellar arachnoid cyst causing precocious puberty is infrequent. The pathogenesis remains unknown in the majority of patients with precocious puberty. Endoscopic ventriculocystocisternostomy procedure is an effective and minimally invasive method in the treatment of these cysts.
