BackgroundRathke cleft cysts (RCCs) are benign cysts arising from the pars intermedia as a result of incomplete obliteration of the Rathke pouch during development of the pituitary gland. The most common presenting symptoms are headaches, visual disturbances, and endocrinopathies. Recurrence of RCCs after surgical treatment is a well-known phenomenon after surgery with reported recurrence rates as high as 30%. Various methods have been employed to reduce the rate of recurrence. Complete cyst wall resection has been associated with increased rates of perioperative cerebrospinal fluid leak, diabetes insipidus, and carotid injury, while inconsistently demonstrating reduced recurrence rates. Marsupialization, in which the cyst cavity is widely exposed and left open with or without a fat graft suspension, has similarly shown increased morbidity without clear improvement in outcomes. We report here the use of a steroid-eluting sinus stent to maintain patency of the cyst opening.Case DescriptionA 39-year-old female presented with a symptomatic RCC. She underwent 4 different surgeries including cyst wall resection, marsupialization, and fat graft placement. She developed short-term symptomatic and radiographic recurrence within 3 months of each surgery. She then underwent placement of a steroid-eluting sinus stent. At 3 months, the patient remained symptom free, without radiographic recurrence and with patent cyst fenestration on nasal endoscopy.ConclusionsRecurrent RCCs are challenging to manage. Strategies to reduce recurrence are typically associated with higher risk and varying success. Stent placement represents a simple, low-risk method of potentially maintaining patency of cyst fenestration.Copyright © 2019 Elsevier Inc. All rights reserved.
