This article provides a systematic literature review of intracranial ectopic Rathke's cleft cysts (RCCs), which are benign congenital lesions located in the sellar and suprasellar regions. The authors present a case of a symptomatic ectopic retrosellar RCC that caused extensive clival erosion. The study includes data on patient demographics, clinical presentation, and treatment details. Surgical approaches varied depending on the cyst's location, and gross total resection was achieved in the majority of cases. The article concludes that further research is needed to better understand the natural history and long-term outcomes of these cysts. [Extracted from the article]

This article discusses the use of intraoperative ultrasound (IUS) as an adjunct to the endoscopic endonasal approach (EEA) for the surgical resection of skull base lesions. The authors present a case study where a novel small-probe IUS was used to assist in the resection of a recurrent Rathke's cleft cyst (RCC) located in an atypical retrosellar region. The small-probe IUS provided real-time imaging feedback and enhanced visualization, allowing for accurate localization of the cyst and surrounding neurovascular structures. The authors conclude that IUS is a promising surgical adjunct that can potentially increase the extent of resection and decrease operation times. [Extracted from the article]
