INTRODUCTION: Sheehan syndrome is a common cause of hypopituitarism in developing countries. Among risk factors, in addition to post-partum haemorrhage, a smaller sellar volume is also believed to predispose to pituitary necrosis. Some earlier studies have reported smaller sellar volume in these patients but involved a small number of patients and lacked matched controls. The main of the present study was to study the sellar volume in a large cohort of patients with Sheehan syndrome and compare it with age- and parity-matched controls...

RATIONALE: Patients with hypopituitarism often have no specific symptoms; that frequently results in missed diagnosis. An acute hypopituitarism crisis can be induced under stressful conditions. Here, we report a rare case of an acute pituitary crisis after lumbar surgery. PATIENT CONCERNS: We describe a 62-year-old female who presented with refractory electrolyte disorders after lumbar surgery. In addition, she developed anorexia, nausea, vomiting, chest cavity effusion, ascites, pericardial effusion, anemia, low blood pressure, bradycardia, and unconsciousness after surgery...

Basilar invagination (BI) is characterized by rostral dislocation of the cervical spine toward the skull base. The craniometrics of the skull base have shown significant differences among craniocervical junction malformations. The sphenoid bone is the center of the skull base; however, no study has evaluated this bone in cases of BI. This was a cross-sectional study of MRI databanks from two institutions of the author's practice between 1985 and 2020. The craniometrics of the sphenoid bone were measured in BI patients and controls...

KEY CLINICAL MESSAGE: Ectopic pituitary adenoma is a rare neoplasm located in the clivus and could mimic other clival tumors. Diagnosis and treatment could be challenging. It should be considered in the differential diagnosis of clival tumors. ABSTRACT: Ectopic pituitary adenomas (EPAs) are isolated adenomas that can be located in variable locations outside the sella turcica and have a normal-appearing pituitary gland. These tumors are rare and are thought to often arise from embryological remnants along the route of Rathke's pouch migration...

Accurate tumor identification during surgical excision is necessary for neurosurgeons to determine the extent of resection without damaging the surrounding tissues. No conventional technologies have achieved reliable performance for pituitary adenomas. This study proposes a deep learning approach using intraoperative endoscopic images to discriminate pituitary adenomas from non-tumorous tissue inside the sella turcica. Static images were extracted from 50 intraoperative videos of patients with pituitary adenomas...

The development of adenohypophysis by differentiating and detaching from the pharyngeal roof results in formation of a functional ectopic pituitary tissue around the Sella turcica. Of the ectopic sites in which pituitary adenoma occurs, clival adenomas are rare and the majority secrete prolactin. We report a case of ACTH-dependent Cushing syndrome. Magnetic resonance imaging revealed a clival mass with sphenoid sinus infiltration and 68 Gallium (Ga) Dodecane tetra acetic acid-NaI3-octreotide positron emission tomography-computed tomography showed intense uptake in the region...

BACKGROUND: Pituitary adenoma (PA) is a type of tumor that develops in the sella turcica and is one of the most frequent intracranial tumors. It belongs to a type of adenoma derived from a single clone of cells in the pituitary gland. PA ranks third among all intracranial tumors, following only gliomas and meningioma. The average prevalence rate is approximately 15% at autopsy and 22.5% at radiological examinations. OBJECTIVE AND SIGNIFICANCE: Most PAs are benign and non-invasive adenomas that can be removed surgically or controlled with medication...

A collision tumor complex is composed of at least two different tumors, benign or malignant, with at least two different histopathological features located adjacent to each other in the exact anatomical localization. Pathologies such as meningiomas, pituitary adenomas, gliomas, and schwannomas may be involved in a collision tumor complex. However, co-occurrence of pituitary adenomas and meningiomas as skull base collision tumors is rare. Here, we present a 65-year-old male patient who presented with olfactory groove meningioma and non-functioning pituitary adenoma as a collision tumor...

Endoscopic skull base surgery has become an integral part of the present neurosurgical armamentarium. The pioneering efforts in which the purely endoscopic transsphenoidal approach was introduced have triggered a growing tide of using the endoscopic endonasal procedures for a large variety of skull base lesions. Because of their anatomical peculiarities, lesions of the sellar and parasellar regions lend themselves very well to the endoscopic endonasal approaches. Apart from the common pathological entities, many other less frequent pathologies are encountered in the sellar and parasellar area...
