Treatment of Rathke’s cleft cysts: Experience at a single centre

Rathke’s cleft cysts are rare benign lesions requiring surgical treatment when they become symptomatic. Transsphenoidal surgery is the recommended therapy due to its efficacy and safety. However, whether the optimal surgical strategy is simple drainage and biopsy or cyst wall resection remains controversial. We report a single center’s experience of a series of 14 Rathke’s cleft cysts treated with transsphenoidal resection of the cyst wall. Postoperatively, there was no cerebrospinal fluid rhinorrhea. The complications included permanent diabetes insipidus, hypocortisolism (including a patient with a coexisting adrenocorticotropic hormone-secreting adenoma), sinusitis and a case of meningitis and intrasellar abscess, one year post-surgery. Visual impairment and headache resolved in all cases. Pituitary dysfunction was restored only in patients with hyperprolactinemia and Cushing’s disease. During the follow-up period (median 29 months) there was no recurrence requiring re-operation. According to our experience, the aggressive approach is associated with good surgical results and with low complication and recurrence rates.
