Preservation of the Posterior Meningeal Artery During Excision of a Foramen Magnum Meningioma: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT A 56‐year‐old woman presented with a foramen magnum meningioma associated with headache and left hypoglossal nerve palsy. A vessel arising from the intradural vertebral artery was identified as the posterior meningeal artery based on an integrated assessment of its origin, course, and relationship to the tumor on three‐dimensional angiography ...

Anatomical variations of the clivus and related craniometric measurements in the adult population of Botswana: A CT-Based study

Translational Research in Anatomy
Introduction: The clivus and foramen magnum are important landmarks in skull base surgeries. Incidental clival anatomical variations such as the fossa navicularis magna and canalis basilaris medianus, can mimic pathological lesions or fractures while the

Evolutionary Signal and Development of the Foramen Dorsum Sellae (Nov.) Across Primates

Journal of Morphology, Volume 287, Issue 9, September 2026.
The dorsum sellae of the sphenoid bone occasionally exhibits an accessory opening, though its significance is unknown. We scored its presence in humans (N = 114) and 30 non‐human primate genera (N = 1468) and combined histological, dissection‐based, and phylogenetic approaches to understand its function. The foramen occurred in 12% of humans and 33% of

Morphometric Features of Posterior Cranial Fossa are Different between Chiari I Malformation with and without Syringomyelia

Global Spine Journal, 2015
Introduction To investigate whether the posterior cranial fossa (PCF) morphology in Chiari I malformation without syringomyelia (CMI only) is different from that in Chiari I malformation with syringomyelia (CMI-S).

Case report: Side-firing intraoperative ultrasound guided endoscopic endonasal resection of a clival chordoma

Frontiers in Oncology, 2023
Clival chordomas are locally invasive midline skull base tumors arising from remnants of the primitive notochord. Intracranial vasculature and cranial nerve involvement of tumors in the paraclival region necessitates image guidance that provides accurate

Upper Versus Middle‐Neck Involvement in TNM‐9 Stage IB Nasopharyngeal Carcinoma: Implications for De‐Escalation and Intensification Strategies

Cancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Background TNM‐9 Stage IB nasopharyngeal carcinoma (NPC) encompasses markedly heterogeneous risk profiles, yet lacks reliable biomarkers to guide the choice between de‐escalation and intensification strategies. This study aimed to explore the prognostic significance of upper‐ and middle‐neck nodal involvement (UNI and MNI) in this population ...

Primary Osteosarcoma of the Skull Base Treated with Endoscopic Endonasal Approach: A Case Report and Literature Review

Journal of Neurological Surgery Reports, 2015
Introduction Giant cell-rich osteosarcoma (GCRO) is a rare pathologic diagnosis, and most cases have involved the appendicular skeleton. We present a challenging diagnosis of GCRO of the skull base treated with an endoscopic endonasal approach.

Clival and Paraclival Lesions: A Pictorial Review

Indian Journal of Radiology and Imaging, 2023
The clivus is a midline anatomical structure in the central skull base. It is affected by a wide range of non-neoplastic, benign and malignant pathologies, some of which typically affect the clivus because of its strategic location and embryological ...

Fibrous Dysplasia of the Clivus

Journal of Korean Neurosurgical Society, 2010
Fibrous dysplasia (FD) of craniofacial structures is well documented, however, its involvement of the clivus is seldom described. We report a case of clival FD in a young man who presented with headache localized to the occipital area. The radiological studies revealed a monostotic disease confined to the clivus, with typical findings of hypointensity ...
