Empty sell syndrome is defined as a herniation of the subarachnoid space within sell, thus, flattening of the pituitary gland. Most of the empty sell cases are found incidentally which this syndrome can be easily missed during maxillofacial radiological examinations. The aim of this paper is to describe two cases of partial empty sell and discuss the differential diagnosis for this condition. Both patients administered to our clinic with pain in the forehead and maxilla. In addition to clinical examination two patients (37 year old male, 70 year old female) were imaged using panoramic radiography, cone beam computed tomography and magnetic resonance imaging. Panoramic radiographies showed no findings in terms of emy sella. However, in CBCT imaging, both patients showed an expansion in the sella turcica and protrusion into the sphenoid sinus. These were more precisely located using 3D CT reconstructions. MR imaging showed intermediate signal on T1-weighted images and high signal on T2-weighted images. MRI findings showed the partial anterior prolapsus of the pituitary gland with cerebrospinal fluid leak in the posterior border of sella turcica. According to MRI findings, the definitive diagnosis was partial empty sell syndrome. Maxillofacial radiologists should be aware of this kind of abnormalities while reporting the entire FOV.

Since many empty cases are accidentally detected, this syndrome can easily be overlooked during maxillophasial radiological examination. The purpose of this article is to present the case of two partial empty and to discuss the distinctive diagnoses related to this situation. Both patients went to our clinic with pain in the maxilla and cervical area. In addition to the clinical examination, both patients (37 years old men and 70 years old women) were taken with panoramic radiograph, conic radiated computer tomography and magnetic resonance imaging. In the Panoramic Radiography, no findings were found concerning empty sell. However, in the KIBT images, both patients saw a proliferation in the turmeric and protrusion in the sfenoid sinus. These findings were fully localized in three-dimensional reconstruction images. In the magnetic resonance imaging, T1 weighted images received a medium level signal and T2 weighted images received a high signal. MRG findings showed that there was a partial anterior prolapsus of the hypofysic gland along with a cerebrospinal fluid leakage at the back border of the turquoise. MRG findings and partial empty are identified with accuracy. Maxillopathic radiologists should also pay attention to this type of pathologies while reporting all structures that enter the viewing area.
