Abstract Amyand's hernia is defined as when the appendix is trapped within an inguinal hernia. While the incidence of this type of hernia is rare, the appendix may become incarcerated within Amyand's hernia and lead to further complications such as strangulation and perforation. Incarceration of the appendix most commonly occurs within inguinal and femoral(More)
Thoracic outlet syndrome (TOS) is a condition arising from compression of the subclavian vessels and/or brachial plexus as the structures travel from the thoracic outlet to the axilla. Despite the significant pathology associated with TOS, there remains some general disagreement among experts on the specific anatomy, etiology, and pathophysiology of the(More)
Tectal plate gliomas are generally benign neoplastic lesions arising in the brainstem which can, with local extension, obstruct the aqueduct of Sylvius and lead to hydrocephalus. Diagnosis is based on initial suspicion fostered by the presentation of an obstructive hydrocephalus followed by physical exam which may potentially reveal indications of pyramidal(More)
The study of human anatomy has traditionally served as a fundamental component in the basic science education of medical students, yet there exists a remarkable lack of firm guidance on essential features that must be included in a gross anatomy course, which would constitute a "Core Syllabus" of absolutely mandatory structures and related clinical(More)
There are a manifold number of variations and anomalies of the origin and course of coronary arteries described in the literature. The incidence of such variations in the general population is reported to range between 0.3 and 1.6 %. Although uncommon, they may be benign or produce symptoms ranging from mild dyspnea to sudden cardiac death, and have been(More)
Scalp dermoid cysts are subcutaneous sacs lined with a stratified squamous epithelium containing developmentally mature ectodermal tissues, including skin, hair follicles, sweat glands, and sebaceous glands. Because they consist of developmentally mature tissues, scalp dermoid cysts are generally benign. Typically, cysts are limited to an extracranial(More)
INTRODUCTION Most sources conclude that the spinal accessory nerve (SAN) is a purely motor nerve. There are some reports that suggest a sensory component, although the exact nature of such sensory fibers has yet to be elucidated. With such discrepancies in the literature and with well-established pain syndromes of unknown etiology following SAN injury, the(More)
Proboscis lateralis is a rare congenitally acquired facial abnormality characterized by a soft-tissue tube- or trunk-like appendage projecting from the surface of the face, most frequently rooted in the medial canthal region. Proboscis lateralis is generally associated with a wide range of concomitant craniofacial anomalies, giving rise to multiple theories(More)
