CONTEXT: LHX4 encodes a LIM-homeodomain transcription factor implicated in early pituitary development. In humans, only 13 heterozygous LHX4 mutations have been associated with congenital hypopituitarism. OBJECTIVE: To evaluate the prevalence of LHX4 mutations in patients with hypopituitarism, and to precise the associated phenotypes. To characterize the functional impact of the identified variants and the respective role of the two LIM domains of LHX4. PATIENTS AND DESIGN: We screened 417 unrelated patients with isolated growth hormone deficiency or combined pituitary hormone deficiency associated with ectopic posterior pituitary and/or sella turcica anomalies for LHX4 mutations (Sanger sequencing)...

INTRODUCTION: Pituitary surgery involving different techniques is often applied to the excision of benign adenomas. Operative interventions involved various approaches and techniques. Endoscopic transsphenoidal approach is the less traumatic route to the sella turcica, avoiding brain retraction, and also permitting good visualization, with lower rates of morbidity and mortality. Although mortality of pituitary surgery decreased by advances in surgical techniques morbidities such as synechiae formation, anosmia, bleeding, nasal septal perforations, drying, and incrustation due to traumatization of the nasal structures such as septum, nasal mucosa, and middle concha are the current problems in pituitary surgery...

The pituitary gland is located in the sella turcica. Pituitary tumors constitute approximately 15% of intracranial benign tumors. "Endo nasal endoscopic trans-sphenoidal" method is an appropriate surgical technique to remove this tumor. In this operation an endoscope enters the nasal cavity through the nostril to reach the floor of the sella turcica. The aim of this study was an anthropometric evaluation of the route of endoscope in this surgery. Two hundred twenty-seven patients (116 women, 111 men) were divided into ≥30, 31 to 61, and ≥61-year age groups...

The occurrence of ganglion cells in the sella turcica, in association or not with a pituitary adenoma, has been rarely reported. Various names have been employed for this rare entity, gangliocytoma being frequently used and recommended by WHO classification. Expression of cytokeratin in these ganglion cells has been previously occasionally reported, a very intriguing observation raising questions on the possible nature and derivation of these cells. We describe the pathological findings in three cases of growth hormone-producing adenomas, all sparsely granulated, showing the presence of a ganglion cell population admixed with an adenomatous component...

BACKGROUND: Thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are a rare cause of secondary hyperthyroidism. Anesthetic management of these patients has not been formally described in the literature. MATERIALS AND METHODS: Patients who underwent resection of a TSH-secreting pituitary adenoma during 1987 to 2012 at a single institution were identified. Preoperative thyroid hormone state, anesthetic management, and outcome were recorded. Hemodynamic associations with intraoperative events were compared between those who were hyperthyroid and euthyroid at the time of surgery...

Skull base architecture is tough to understand because of its 3D complex shape and its numerous foramen, reliefs or joints. It is especially true for the sphenoid bone whom central location hinged with most of skull base components is unique. Recently, technological progress has led to develop new pedagogical tools. This way, we bought a new real-time three-dimensional insight of the sphenoid bone that could be useful for the teacher, the student and the surgeon. High-definition photography was taken all around an isolated dry skull base bone prepared with Beauchêne's technique...

We report a primary central nervous system (CNS) perivascular epithelioid cell tumor (PEComa) in a middle-aged female patient. The tumor occurred in suprasellar location with secondary extension into the sella turcica. The patient presented with intracranial hemorrhage and an altered level of consciousness. The tumor had morphologic features matching those of other previously described TFE3-translocated PEComas, including epithelioid morphology, diffuse and strong nuclear immunoreactivity for TFE3, and minimal staining with myoid markers...

INTRODUCTION: Sella turcica is an important cephalometric structure and attempts have been made in the past to correlate its dimensions to the malocclusion. However, no study has so far compared the size of sella to the jaw bases that determine the type of malocclusion. The present study was undertaken to find out any such correlation if it exists. MATERIALS AND METHODS: Lateral cephalograms of 110 adults consisting of 40 Class I, 40 Class II, and 30 Class III patients were assessed for the measurement of sella length, width, height, and area...
