The sellar/juxtasellar region comprises the bone component of the sella turcica, pituitary gland, cavernous sinus, and suprasellar cistern. Abnormalities in this region can be attributed to underproduction or overproduction of hormones or to the neurological signs and symptoms resulting from the compression of adjacent structures. Magnetic resonance imaging (MRI) is currently the imaging method of choice, having supplanted computed tomography. The aim of this study was to demonstrate the common and uncommon imaging aspects of sellar and juxtasellar changes, which could facilitate the differential diagnosis...

BACKGROUND: Empty sella is the neuroradiological or pathological finding of an apparently empty sella turcica containing no pituitary tissue. The prevalence of primary empty sella, i.e., empty sella without any discernible cause, is not precisely known; estimates range from 2% to 20%. Technical advances in neuroradiology have made empty sella an increasingly common incidental finding. It remains unclear whether, and to what extent, asymptomatic adult patients with an incidentally discovered empty sella should undergo diagnostic testing for hormonal disturbances...

REVIEW
Sylvia L Asa, Ozgur Mete
Pituitary pathology is one area of endocrine pathology that is highly dependent on immunohistochemistry. There is a wide range of disorders that occur in and around the sella turcica, and the distinction of tumor-like lesions from neoplasms requires careful evaluation. The diagnosis, prognosis, and predictive features of neoplasms in the sellar region are all dependent on the application and interpretation of biomarkers of cell differentiation, hormonal activity, subcellular morphology, and proliferation. As in hematopathology, the number of biomarkers has increased dramatically and continues to increase...

INTRODUCTION: Goldenhar syndrome is a rare disease with hemifacial microsomia and craniofacial disorders originating from the first and second branchial arches, such as ocular, auricular, and vertebral anomalies. The complexity and variety of the ways in which the disease presents itself usually need several examinations. In this study, we aimed to evaluate both craniofacial and vertebral skeletal anomalies and asymmetries between the nonaffected and affected sides in patients with Goldenhar syndrome by using cone-beam computed tomography...

The objective of the present study was to determine the biological age of the unrecognized individuals based on the analysis of CT-scanograms of the skull and the craniovertebral region in the sagittal projection. We investigated the structure of the spongy substance of the clinoid plate of the sella turcica and the clivus of the cranium, involution of the vertebrae configuration in the medial atlantoaxial articulation, frontal and sphenoidal sinuses. A total of 80 skulls of Caucasoid individuals at the age ranging from 4 to 84 years belonging to an Eastern Slavonic population (free from the pathological lesions in the above cranial structures) were available for the examination...

BACKGROUND: Prolactinomas may rarely present with meningitis and cerebrospinal fluid (CSF) rhinorrhea secondary to erosion of the wall of the sella turcica. It is even more uncommon for this abnormal communication to be caused by an ectopic prolactinoma arising from the sphenoid sinus and eroding into the sella. This atypical growth pattern makes diagnosis very difficult because there may be no displacement of the normal pituitary gland. The first reported case of a patient with an ectopic prolactinoma originating within the sphenoid sinus presenting primarily with meningitis is presented, and the management strategy and surgical and nonsurgical treatment options are discussed...

Presentation of a patient with an orbital intracranial penetrating screwdriver injury. The patient had been playing with the screwdriver at the time of the accident, he fell and the screwdriver penetrated his right orbit. Imaging revealed the position of the foreign body, which went from the medial orbital wall, extraconal and medial of the right internal carotid artery, through the sella turcica to the dorsum sellae. The patient had no intracranial hemorrhage. There was hardly any bleeding. The surgical removal of the screwdriver was carried out without complications...

Aim Sella turcica bridging and ossified carotico-clinoid ligament are two variants of the sella turcica, the origin of which is partially unknown. These variations should be properly recognised, as they may hamper the removal of the anterior clinoid process in surgical procedures. Therefore, our aim was to determine the prevalence of these two anatomical variants and to investigate their prevalence according to patient sex and age in a series of maxilla computed tomography scans. Materials and methods We revised 300 computed tomography scans of the head from northern Italian patients, stratified into three age groups (18-40 years, 41-60 years, >60 years): a logistic regression analysis was used to explore an association of sella turcica bridging with age and sex through Matlab software, also including a test for the extracted model ( P < 0...
