ABSTRACT

Introduction: The sellar spine is a small bone formation, congenital, which is formed in the front back part of the Sella turcica. It is asymptomatic and may be detected incidentally. Both the Computerized Tomography as well as the Magnetic Resonance Imaging, may show the sellar spine.
Objective: The present work is aimed to consider the possibility of the sellar spine when detecting an image of calcium aspect in the inner part of the Sella turcica.
Cases presentation: Our casuistry comprises three female patients, who showed the sellar spine as an incidental finding. In the first patient, Magnetic Resonance imaging was performed due to a chronic cephalalgia. In the second patient, with hyperprolactinemia, it was concluded that the sellar spine may cause a hypophiseal dysfunction. The third case was another women with cervical trauma background, who showed sellar spine, through Computerized Tomography, and not related or nor associated to the traumatic background.
Discussion and analysis: The bibliographic revision has few reported cases of sellar spine. Several cases associated to the hypophiseal dysfunction are mentioned.
Conclusions: Sellar spine is an anatomical variable which is randomly detected. Current diagnosis methods through imaging have enough sensibility and specificity to show this small intrasellar bone structure. In the three cases presented, sellar spine was detected, two of them with an anatomical variant and one was related to the sellar spine with hyperprolactinemia.
