Spontaneous Resolution of Asymptomatic Pediatric Suprasellar Arachnoid Cysts: Report of 2 Cases and Review of the Literature

Introduction: Sellar/suprasellar arachnoid cysts are infrequent nonneoplastic cystic lesions that account for approximately 1% of all arachnoid cysts. While various surgical treatment options have been proposed for symptomatic lesions, treatment guidelines regarding the management of asymptomatic sellar/suprasellar arachnoid cysts remain to be elucidated. This case series aims to provide a better insight into the management and outcomes of such lesions. Case Presentation: We discuss 2 pediatric patients diagnosed with sellar/suprasellar arachnoid cysts who remained asymptomatic and demonstrated spontaneous gradual resolution of their arachnoid cysts on subsequent imaging studies. Conclusion: Review of the literature identified only a handful of previously reported cases of spontaneously disappearing suprasellar arachnoid cysts. There might be a role for conservative management of sellar/suprasellar arachnoid cysts in certain patients who remain asymptomatic.
