Jugular foramen neurilemmoma is frequently manifested as a jugular foramen syndrome or extraaxial mass. Neurilemmoma arising from the cranial nerves of the foramen, although rare, may be manifestated as an intracranial or extracranial mass lesion. When the tumor is located only in the intracranium, it is often misdiagnosed as an acoustic neurinoma or a brainstem tumor because of their similarit...

The paper presents anatomical considerations on the pterygoalar bar and the pterygoalar foramen of the human skull. The pterygoalar bar is a bony bridge that stretches between the lateral pterygoid lamina and the greater wing of the sphenoid bone, while the space under this bar is termed the pterygoalar foramen. These structures were noted in 5 out of 70 investigated skulls. The length of the p...

Lateral disk herniation into the intervertebral foramen if not recognized may result in a negative surgical exploration. The condition is readily recognized by computed tomography (CT), which demonstrates a soft-tissue mass in the intervertebral foramen, focal protrusion of the posterolateral margin of the disk into the foramen, absence of dural sac deformity, and occasionally the presence of c...

Introduction Knowledge of variations in foramen tranversarium of first cervical vertebrae is surgically relevant, as its anatomical relation with third part of vertebral artery is one of the proposed causative factor for cervicogenic headache. This study was aimed to determine the incidence, morphological and morphometrical variations of foramen transversarium (FT) of atlas vertebrae in North I...

OBJECTIVES The objective of this study was to investigate the ligaments in the exit zone of lumbar foramen and describe their anatomic relationships with adjacent structures. Few studies have been reported on the ligaments of foramen and the anatomic relationships on the lumbar level. The ligament described in this study is novel since it has not been reported previously. METHODS Ten male and...

1 of 2 DESCRIPTION The variability of the obturator artery inside the pelvis is well known; however in the thigh only two branches encircling the obturator foramen are described. With the evolution of minimally invasive trans-obturator approaches to pelvic surgery the anatomy in this area needs to be better understood. Trans-obturator approach has been shown clinically more effective and less i...

STUDY DESIGN Prospective study based on magnetic resonance (MR) imaging of the lumbar spinal root of the intervertebral foramen. PURPOSE This study was to compare MR three-dimensional (3D) sequences for the evaluation of the lumbar spinal root of the intervertebral foramen. OVERVIEW OF LITERATURE The diagnosis of spinal disorders by MR imaging is commonly performed using two-dimensional T1-...

Address for Correspondence: Prof Dr. Suniti Raj Mishra, Professor and Head, Department of Anatomy, G.S.V.M. Medical College, Kanpur, Uttar Pradesh, India. E-Mail: [email protected] Background: The mandibular foramen, is the emerging point of the neurovascular bundle which makes it fundamental for performing anaesthetic techniques for desensitization of the mandible in oral surgery intervent...

Emissary sphenoidal foramen is an inconstant foramen that gives passage to an emissary vein that connects pterygoid venous plexus with cavernous sinus, the importance of which lies in the fact that an infected thrombus from an extracranial source may reach cavernous sinus. The aim of the present study was to identify the incidence of emissary sphenoidal foramen. 100 dry adult human skulls were ...

The objectives of the present study were to study the prevalence of the parietal emissary vein in adult South Indian population and to study the distance of foramen from the sagittal suture. There were 58 adult human skulls in the present study which were available at the anatomy department of our institution. The study included 116 parietal bones which have been observed macroscopically for th...
