Blake pouch cyst

Blake pouch cyst is a non-syndromic usually benign cystic malformation of the posterior fossa characterized by a midline outpouching of the superior medullary velum into the cisterna magna that results from failure of the rudimental fourth ventricular tela choroidea to regress during embryogenesis. Patients can be asymptomatic or present in childhood or adulthood with clinical manifestations of hydrocephalus such as headache hypotonia vertigo syncope vomiting blurred or double vision nystagmus papilledema and delayed gait development.
