Intrasphenoidal Rathke's Cleft Cyst: An Uncommon Feat

Usually occurring entirely intrasellarly or extending suprasellarly (intra-suprasellar), Rathke's cleft cysts (RCCs) can present with an intrasphenoidal location. Extrasellar positions are rare. To date, only seven patients with intrasphenoidal RCC have been reported in the literature. Despite the rarity of the condition and the lack of pathognomonic radiological features, preoperative diagnosis remains challenging. A trans-sphenoidal approach can be adopted to treat this type of cyst, which has great clinical relevance. Awareness of this different presentation of RCC before respective management may be of value in its approach. Intrasphenoidal RCC should be diagnosed preoperatively and the surgical approach should be changed accordingly by aspiration and partial removal before the histological examination.
