Craniometric Analysis of Foramen Magnum for Estimation of Sex

, 2013
Human skull is shown to exhibit numerous sexually dimorphic traits. Estimation of sex is a challenging task especially when a part of skull is brought for medicolegal investigation. The present research was planned to evaluate the sexing potential of the

Surgical Resection of a Foramen Magnum Meningioma—A Rarely Encountered Skull Base Tumour in Trinidad

Caribbean Medical Journal, 2021
Tumours of the foramen magnum are infrequent compared to other locations within the neuraxis. Meningiomas are one of the most frequently encountered tumours of the nervous system, but only 1.8 to 3.2% actually originate within the foramen magnum. However,

Sexual dimorphism and clinical importance of posterior condylar canal

National Journal of Clinical Anatomy, 2022
Background: The posterior condylar canal (PCC) and its associated emissary vein are important anatomical landmarks for juxta-condylar approach and extreme lateral approach for exposing lesions in the region lateral to the foramen magnum.

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Foramen magnum metastatic malignant melanoma

, 2003
The foramen magnum as a site for brain metastasis is extremely rare. We report the case of a 24-year-old male who presented with features of increased intracranial pressure and lower cranial nerve palsies.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Morphological observation of occipital condyle position in Chinese skulls and potential clinical significance

Folia Morphologica
BACKGROUND: We aimed to study the anatomy of the Chinese occipital condyle and its position relative to the occipital foramen and skull. MATERIALS AND METHODS: Measurements were taken from 106 adult Chinese skulls using a Cartesian coordinate system ...

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Foramen Magnum Meningiomas: Still a Big Challenge

Objective: Foramen magnum meningiomas (FMMs) are rare but challenging for neurosurgeons to remove because of their anatomic location where vital neuro-vascular structures exist.

A morphometric and morphological analysis of the foramen magnum, hypoglossal canal and occipital condyles in a select South African population

Folia Morphologica
BACKGROUND: The foramen magnum is a centralised structure found at the base of the skull. This orifice is a passageway that allows secondary structures, such as the medulla oblongata and meninges, to pass through.
