Rathke cleft cyst (RCC) has a recurrence rate of 10% to 22%, and preventing recurrence is challenging. For patients who experience persistent recurrence of RCC, placement of steroid-eluting bioabsorbable intrasellar stents has been rarely described. However, recurrences are often delayed, suggesting that dissolvable stents may not be successful long-term. The release of steroids in close proximity to the pituitary gland may also unintentionally influence the hypothalamic-adrenal-pituitary axis.
The authors present a case of a 66-year-old woman with a persistently recurrent RCC who underwent drainage of her cyst with placement of a nonabsorbable intrasellar stent in the form of a tympanostomy tube. After repeat transsphenoidal drainage of her cyst, a tympanostomy T-tube was placed to stent open the dural aperture. Postoperatively, the patient’s condition showed improvement clinically and radiographically.
Placement of an intrasellar stent for recurrent RCC has rarely been described. Steroid-eluting bioabsorbable stents may dissolve before RCC recurrence and may have an unintentional effect on the hypothalamic-pituitary-adrenal axis. The authors present the first case of nonabsorbable stent placement in the form of a tympanostomy tube for recurrence of RCC. Additional studies and longer follow-up are necessary to evaluate the long-term efficacy of both absorbable and nonabsorbable stent placement.
