management of periventricular and intraventricular arachnoid cysts. MRI T1 axial sequence with an arrow showing the site of cystoventriculostomy

Endoscopic

management of periventricular and intraventricular arachnoid cysts. a MRI T1 axial sequence showing left quadrigeminal cyst in 45 y old female patient. b Follow-up CT brain after 1 month postoperatively showing reduction of the cyst size. The procedure applied was endoscopic ventriculocystostomy through left frontal burr hole and left lateral ventriculocystostomy

Endoscopic

management of periventricular and intraventricular arachnoid cysts. MRI T2 sagittal sequence with an arrow identifying the site of ventriculocystostomy and cystocisternostomy

Endoscopic

management of periventricular and intraventricular arachnoid cysts. a MRI T2 axial sequence showing suprasellar arachnoid cyst bulging inside the third ventricle in a 3-year-old male. b MRI T2 sagittal sequence showing suprasellar arachnoid cyst bulging through the foramen of monro. c Follow-up MRI T2 sequence after 3 months postoperatively showing reduction of the cyst size.

Endoscopic

management of periventricular and intraventricular arachnoid cysts. a MRI T1 axial sequence with contrast showing posterior fossa cyst related to the fourth ventricle and compressing it. b Endoscopic view showing identification of the fourth ventricular wall from inside the cyst and performing endoscopic cystoventriculostomy. c Applying a fenestration between the cyst and the ventricle with a Fogarty catheter. d Endoscopic navigation inside the fourth ventricle with identification of the aqueduct of Sylvius

Endoscopic

management of periventricular and intraventricular arachnoid cysts. a MRI T1 axial sequence showing left parietal paraxial arachnoid cyst effacing the lateral ventricle in a 1-year-old female. b MRI T1 axial sequence showing a decrease of the size of the cyst after 1-year follow-up. The procedure applied was endoscopic cystoventriculostomy through the left parietal burr hole

Endoscopic

management of periventricular and intraventricular arachnoid cysts. a MRI T1 axial sequence showing quadrigeminal arachnoid cyst bulging inside the lateral ventricle in a 6-month-old male. b MRI T2 axial sequence after 1 month showing marked decrease in the size of the cyst and resolution of hydrocephalus with development of chronic subdural hygroma after performing endoscopic ventriculocystostomy and third ventriculostomy. c Follow-up CT after 3 months postoperatively showing reduction of the size of chronic subdural hygroma without intervention
