Symptomatic Rathke cleft cyst

Abstract

Rathke cleft cysts (RCC) are uncommon intrasellar lesions. Although their clinical manifestations, radiological features and treatment are frequently reported, controversy remains as a result of their rarity. We reviewed the preoperative clinical manifestations, neurological examination findings, visual acuity and fields, endocrinological function, radiographic study findings, surgical and pathological records, and prognosis of 45 patients with RCC (21 males, 24 females, average age: 47 years) admitted to our department between January 2002 and January 2011. The most common clinical manifestations included headaches, and visual and hormonal disturbances. Most RCC were intrasellar with a suprasellar extension. The most common MRI patterns were hypointense on T1-weighted and hyperintense on T2-weighted images, isointense on T1-weighted and hyperintense on T2-weighted images, and hyperintense on T1-weighted and hyperintense on T2-weighted images. Aspiration and biopsy of the cyst wall were performed in most patients. Most patients experienced improved headaches and visual disturbance, but the hormonal disturbance rarely returned to normal, especially in those patients with a serious preoperative hormonal disturbance. The recurrence rate was 14%, which was associated with the extent of cyst removal, inflammation and rim enhancement, as well as the surgical approach. Aspiration and biopsy of the cyst wall still seems to be an effective treatment for most RCC for its low morbidity and good prognosis. Conservative treatment and close follow-up may be suitable for small cysts with subtle clinical manifestations.
