Abstract
Rathke cleft cysts (RCC) are the embryological remnants of the pars intermedia within the Rathke’s pouch, and they represent the benign end of a spectrum of lesions originating from this region. RCCs are commonly small asymptomatic lesion; however, they often attain large size and exert mass effect on surrounding vital neurovascular structures, and hence become symptomatic. RCCs are the target of transsphenoidal surgery when symptomatic; however, surgical management of RCC is challenging, because aggressive resection may carry a high risk of complications - commonly diabetes insipidus (DI), due to the embryological proximity to the neurohypophysis – whereas sub-optimal resection may result in higher rates of cyst recurrence. In this commentary, we highlight nuances in diagnosis, and our philosophy to optimize surgical treatment of RCCs.
