Abstract
The objective is to describe a rare clinical case of a suprasellar cyst formed after implantation of a ventriculoperitoneal shunt. Clinical observation . A female patient, 51 years, suffered non-traumatic subarachnoid intraventricular hemorrhage, acute obstructive and subsequently normal pressure hydrocephalus requiring implantation of a ventriculoperitoneal shunt. In several years, the patient developed a suprasellar cyst manifesting through cerebral symptoms. Results . Two (2) surgeries were performed. During the 1st surgical intervention, endoscopic ventriculostomy was performed with positive outcome (full regression of the symptoms). After 6 months, cyst recurrence was confirmed, and endoscopic ventriculocystocisternostomy with replacement of a low pressure pump with intermediate pressure pump was performed. Full regression of neurological disorders was observed; magnetic resonance imaging did not show cyst recurrence 6 months after the 2 nd surgery. Conclusion . This clinical observation expands our knowledge on the diversity of mechanisms of suprasellar arachnoid cyst formation and demonstrated effectiveness of one of the techniques for prevention of cyst formation in the context of ventriculoperitoneal shunt.
