BACKGROUND: Rathke's cleft cyst (RCC) is one of the most common incidentally discovered sellar lesions, while symptomatic cases are relatively rare. Surgical treatment is recommended for symptomatic patients to drain the cyst content and to remove the capsule safely. The aim of this study was to clarify the clinical features, surgery considerations and therapy outcomes of symptomatic RCCs. METHODS: Totally 42 patients (19 males and 23 females) were retrospectively reviewed with the diagnosis of RCCs under surgery resection at the Affiliated Hospital of Medical College, Qingdao University between January 2005 and December 2010. RESULTS: Patients' age ranged from 6 to 67 years (mean of 41.6 years). The duration of symptoms ranged from 4 days to 10 years. Headache (69%), visual impairment (36%), and pituitary dysfunction (10%) were the most common presenting symptoms. The maximum diameter of cysts ranged from 6.0 to 46.7 mm (mean of 20.07 mm). Of the 42 patients, 36 underwent endonasal transsphenoidal approach and the others underwent transcranial approach. Thirty patients had a subtotal resection and decompression, while 12 patients had a total cyst resection. Cysts of 28 patients were lined by simple cubical or columnar epithelium, and cysts of 34 patients were filled by amorphous colloid material, that was the characteristic of RCCs. The majority of patients presented with a simple headache, and 93% of this group experienced a complete improvement after surgery. Twelve of 15 patients (80%) with preoperative visual deficits experienced an improvement in their vision after surgery. All of those patients with pituitary dysfunction experienced an improved endocrine status. The endocrinological complication usually was diabetes insipidus, and postoperative transient diabetes insipidus occurred in 13 (31%) patients without any permanent diabetes insipidus. The overall recurrence rate was 7% at a mean follow-up of 22 months (range 12 - 60 months). CONCLUSIONS: Surgical treatment is to drain the contents of the cyst and to remove the capsule as much as possible under the precondition that does not increase the complications. Biopsy and decompression procedures are recommended for most cases.
