BACKGROUND AND PURPOSE: The topography of craniopharyngiomas has proved fundamental in predicting the involvement of vital brain structures and the possibility of achieving a safe radical resection. Beyond the imprecise term "suprasellar," indiscriminately used for craniopharyngiomas, an accurate definition of craniopharyngioma topography should be assessed by preoperative MR imaging. The objective of this study was to investigate the MRI findings that help define craniopharyngioma topography...

A 54-year-old woman was admitted to our hospital for detailed examination of acromegaly because she noticed bilateral hand and finger swelling at the age of 43 and plantar thickening, facial changes and unclear articulation at the age of 49. She had prominent brow ridges, mandibular protrusion, and enlargement of the hands, feet, nasal wings, lips and tongue. Her growth hormone (GH) level was 39.8 ng/ml, insulin-like growth factor-1 (IGF-1) level was 717 ng/ml, GH level was not suppressed (22.9 ng/ml) during a 75-g oral glucose tolerance test (OGTT)...

Rathke's cleft cyst is a cystic disease that occurs in the sella turcica or, occasionally, in the suprasellar area. An ectopic Rathke's cleft cyst is extremely rare, and its nature is less well understood. The authors report the case of a 14-year-old girl who presented with a growing cystic lesion in the prepontine cistern, immediately behind the dorsum sellae. Preoperative imaging and intraoperative investigation showed part of the cyst wall continuing into the dorsum sellae, to the pituitary gland. The cisternal portion of the cyst wall was totally resected via a right subtemporal approach...

OBJECTIVES: To test the null hypotheses that the positions of the glenoid fossae and mandibular condyles are identical on the Class I and Class II sides of patients with Class II subdivision malocclusion. MATERIALS AND METHODS: Retrospective three-dimensional (3D) assessments of the positions of the glenoid fossae and mandibular condyles were made in patients with Class II malocclusion. Relative to a fiducial reference at the anterior cranial base, distances from the glenoid fossae and condyles were calculated in pretreatment cone beam computed tomographic scans of 82 patients: 41 with Class II and 41 with Class II subdivision malocclusions...

History A 53-year-old man experienced headache and double vision that progressed over 1 year. After a traumatic fall, he was hospitalized, and proptosis was identified at physical examination. Laboratory tests were remarkable for leukocytosis. Hematocrit level, thyroid stimulating hormone level, autoimmune antibody level, erythrocyte sedimentation rate, and C-reactive protein level were normal. Computed tomography (CT) of the head revealed bilateral intraconal masses, for which magnetic resonance (MR) imaging of the orbits was subsequently performed ( Fig 1 )...

OBJECTIVE The middle clinoid process (MCP) is a bony projection that extends from the sphenoid bone near the lateral margin of the sella turcica. The varied prevalence and morphological features of the MCP in populations stratified by age, race, and sex are unknown; however, the knowledge of its anatomy and preoperative recognition on CT scans can aid greatly in complication avoidance and management. The aim of this study was to further illustrate the surgical anatomy of the parasellar region and to quantify the incidence of MCP and caroticoclinoid rings (CCRs) in dried preserved human anatomical specimens...

A retrospective cohort study of patients with tuberculum sellae meningioma (TSM)-associated sphenoidal pneumosinus dilatans (PSD) over a recent epoch was evaluated using a propensity-matched morphometric analysis. A total of 38 patients with TSM and sphenoidal PSD were identified and matched by age and sex to 32 patients without tumors (controls). Overall, no significant difference between test and control groups was noted in sphenoid sinus size or other parameters; however, significantly greater mean distance from the posterior margin of the planum sphenoidale to the diaphragma sella (0...

BACKGROUND: Choroid plexus papillomas (CPPs) are rare benign tumors, and the pigmented subtype is observed even more rarely. CASE DESCRIPTION: We present the case of a 43-year-old woman with complaints of headache and progressive left monocular visual deterioration, whose initial plain computed tomography CT scan showed an ovate high-density tumor located within the insellar region. Magnetic resonance imaging revealed a homogeneously contrast-enhancing tumor extending from the sella turcica to the suprasellar cistern...

BACKGROUND: There is evidence that cure rates and complications are influenced by the case load in neurosurgical centres performing transsphenoidal pituitary surgery. Although Australian centres may perform relatively small numbers of these procedures, there have been few published audits of their performance. AIMS: To conduct an audit of surgery for pituitary tumours between 2012 and 2014 in the only public hospital neurosurgical unit in the state of Western Australia...

Spindle cell oncocytoma (SCO) of the sella turcica is characterized as a WHO grade I non-endocrine neoplasm of the sella turcica. Histologically, these tumors contain spindled and variably oncocytic cellular processes. Although SCOs lack immunoreactivity for neuroendocrine markers and pituitary hormones, they are clinically indistinguishable from non-functioning pituitary adenomas. In contrast to the initially described benign clinical course, several reports have subsequently illustrated cases with multiple recurrences with or without histological features of anaplasia in the form of nuclear pleomorphism, frequent mitoses, high Ki-67 index, and/or necrosis...

Pituitary abscess is a rare but critical disorder caused by an infectious process where purulent material accumulates inside the sella turcica. Since symptoms, signs and radiographic characteristics of pituitary abscess are similar to several other pituitary lesions, correct diagnosis before surgery is challenging. In this article, two cases of pituitary abscess treated in our department are reported, followed by a literature review. In these two cases, both patients presented with intermittent fever. Magnetic resonance imaging revealed a suprasellar lesion with rim enhancement after contrast injection...

The field of pituitary surgery was born in the first decade of the twentieth century in Europe, and it evolved rapidly with the development of numerous innovative surgical techniques by some of the founding fathers of neurosurgery. This study investigates the pioneering Italian treatise on pituitary surgery, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), published in 1911 by Giovanni Verga (1879-1923), a surgeon from Pavía and one of Golgi's disciples. This little-known monograph compiles the earliest experience on pituitary surgery through the analysis of the first 50 procedures performed between 1903 and 1911...

BACKGROUND: Rathke cleft cysts (RCCs) and pituitary adenomas (PAs) are thought to have a common embryonic ancestry; however, PAs with a concomitant RCC inside the sella turcica are rarely observed. Ectopic pituitary tumors are also rare. CASE DESCRIPTION: We present the case of a 65-year-old woman with an ectopic RCC in the sphenoid sinus and outside the sella turcica concomitant with an adrenocorticotropic hormone (ACTH)-staining, clinically silent PA. The patient had headache but no endocrine or visual disturbances...

BACKGROUND: Ectopic pituitary adenomas (EPAs) are rare, and the suprasellar cistern seems to be the most common location. At this time, no detailed original classification, diagnosis, or treatment protocols for suprasellar pituitary adenomas (SPAs) have been described. CASE DESCRIPTION: A 19-year-old man showed visual disturbances and lack of libido for 3 years, he suffered a sharp decline in vision with only light perception in the last week. Magnetic resonance imaging scans revealed a large suprasellar cystic lesion with a normal pituitary in the sella turcica...

The classical term "pituitary apoplexy" (PA) describes a clinical syndrome usually characterized by abrupt onset of headache accompanied by neurologic and/or endocrinologic deterioration due to sudden expansion of a mass within the sella turcica as a result of hemorrhage or infarction within a pituitary tumor and adjacent pituitary gland. PA is a medical emergency and a difficult diagnosis to establish. Thus this article reviews the presenting symptoms of PA patients to help clinicians recognize or at least suspect this critical condition early on...

The aim of this study was to measure line segments and areas of sella turcica on lateral cephalograms with respect to the clinical diagnosis of facial phenotype of patients with neurofibromatosis type 1 (NF1). Special attention was given to correlate the measured values with certain tumour types that are typical for this disease. Material and methods: Lateral cephalograms of 194 individuals were investigated. Patients with NF1 were further divided according to the detection and topography of facial plexiform neurofibromas (PNF) taking into account the distribution pattern of the trigeminal nerve...

INTRODUCTION: Head and neck skeletal anomalies or normal variants might predict the occurrence of palatally displaced impacted maxillary canines. Despite their clinical importance, studies in this regard are rare, especially when it comes to vertebral anomalies. METHODS: This case-control study was performed on cephalographs of 35 orthodontic patients (11 male, 24 female) with palatally displaced canines (PDC) and 75 patients without them (29 male, 46 female). PDC were diagnosed on panoramic and lateral cephalographs and from clinical reports...
