Abstract

Objective: To evaluate the features and diagnostic value of magnetic resonance imaging (MRI) for tuberculum sellae meningioma. Methods: Presurgical MRI features of 59 patients with histopathologically identified tuberculum sellae meningioma between January 1995 and December 2015 were analyzed retrospectively. Results: Fifty-nine patients including 15 males and 44 females were evaluated. The bases of the tumors were all located around the tuberculum sellae or diaphragmasellae. On MRI T1-weighted image (T1WI), all tumors showed slightly iso- or hypo-intense and iso- or hyper-intense on T2WI. Obvious homogenous enhancement of tumor on enhanced scanning images of MRI was seen in 57 cases, and the remaining 2 cases showed uneven enhancement. The dural tail sign on enhanced scanning images was observed in 45 cases. Conclusion: MRI examination plays an important role in qualitative diagnosis and localization of tuberculum sellae meningioma, providing a valuable guide for selection of surgical approach, evaluation of the extent of tumor resection, and the prediction of operation risks.
