Rapid Effect of Gamma Knife Radiosurgery on Clivus Metastasis: A Case Report

Indian Journal of Neurosurgery, 2016
Breast cancer may cause distant metastasis even though there is no local recurrence. Disease can spread to any part of body via lymphoid and hematogenous way, and clivus is one of the most common locations.

3D Geometric Morphometric Analysis on Sexual Dimorphism in the Sella Turcica in Romanov Sheep Using CT Scan

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Three‐dimensional geometric morphometric analysis is a shape analysis method used to explain sexual dimorphism. In this context, a total of 13 anatomical landmarks were defined and analysed in the study, resulting in sex‐related shape variations. The study identified sex‐related morphological differences in the sella turcica structures of Romanov sheep

Gender estimation using machine learning algorithms from computed tomography images of clivus

Medicine Science
The clivus, which is involved in the formation of the skull base, is an important material in gender prediction with its fusion structure. The aim of this study is to predict the gender of adult individuals using Machine Learning (ML) algorithms and ...

Clivus Rathke cleft cyst: case report of a rare disease and literature review [PDF]

Rhinology Online, 2018
Background: Rathke's cleft cysts (RCCs) are nonneoplastic epithelial lesions derived from true remnants of the embryological Rathke's pouch. They are commonly located in the sellar and suprasellar region and usually appear as an asymptomatic mass. Case:

Anatomic Diagram as a Novel Assessment Strategy for Subclinical Local Residual Disease in Sinonasal Squamous Cell Carcinoma and Intestinal‐Type Adenocarcinoma

International Forum of Allergy &Rhinology, Volume 16, Issue 4, Page 333-344, April 2026.
ABSTRACT Objective In the last two decades, transnasal endoscopic surgery (TES) has become pivotal in the management of sinonasal tumors. This approach involves a multiblock tumor resection, adding complexity to the interpretation of surgical margins after pathological examination.

Transnasal Ventral Brainstem Epidural Electrical Stimulation Enhances Consciousness in Anesthetized Sheep: A Feasibility Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
This study provides the first experimental evidence of a novel transnasal ventral brainstem epidural electrical stimulation approach in anesthetized sheep and demonstrates that this procedure can induce behavioral arousal and cortical electrophysiological changes toward a wake‐like state, holding promise for the treatment of chronic disorders of ...

Contralateral Nasoseptal Flap for Middle Cranial Fossa Defects After Osteoradionecrosis

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 2, April 2026.
Contralateral nasoseptal flaps are a valuable salvage option for reconstruction of large skull base defects when the ipsilateral pedicle is unavailable. We describe a reproducible step‐by‐step technique combining a contralateral Hadad–Bassagasteguy flap with a reverse‐rotation septal mucosal flap for repair of middle cranial fossa defects. The approach

Diffuse Infiltrating Perisellar Mass Mimicking Polyneuritis Cranialis

European Journal of Neurology, Volume 33, Issue 4, April 2026.
ABSTRACT Background Subacute oculomotor dysfunction encompasses a broad differential diagnosis, including autoimmune, infectious, vascular, and neoplastic etiologies. Primary skull base diffuse large B‐cell lymphoma (DLBCL) is a rare but treatable cause of cranial nerve dysfunction and may present subtly on conventional neuroimaging.
