PURPOSE: @entity976 cysts are non neoplastic lesions of the sellar area that seldom are symptomatic. Their incidence has been underestimated before magnetic resonance imaging (MRI). The aim of this work was to assess the value of MRI in the diagnosis and differential diagnosis of @entity976 cyst based on a retrospective review of 12 cases and a review of the literature. @entity1 AND METHODS: We retrospectively reviewed the MRI features of 12 @entity1 with @entity976 cyst collected over 4.5 years. @entity1 included ten females and two males (mean age: 39 years). The most common presentation was the association of @entity1834 and @entity4611 . MRI examinations were performed using a 1.5 Tesla system, T1 and T2 weighted sequences performed before and after Gd- DTPA injection. Signal intensity, shape, size and location of the lesion were analyzed. RESULTS: In all cases, MRI examination showed a @entity5409 of variable size and signal intensity. The cyst was purely intrasellar in nine cases and a suprasellar extension was noted in three cases. Five @entity1 underwent surgery providing pathological confirmation, four underwent routine follow-up and three were lost of follow-up. CONCLUSION: We conclude that MRI is an efficient tool for diagnosis, allowing appropriate medical decision making.
