Degenerated extensor hallucis brevis accessorius: A case report.

The extensor hallucis brevis accessorius has rarely been mentioned in the extant medical literature. Here, we present the case of a cadaver found to have such a muscle and discuss the findings. Specifically, the muscle was observed to be degenerated both grossly and histologically.

Remarkably Elongated Coronoid Processes: A Cadaveric Case Report.

An elongated coronoid process (ECP) can lead to impingement of the coronoid process on the body or arch of the zygomatic bone when opening the mouth. The etiology of ECP is unclear, but several theories have been postulated. We present a case of an ECP found in a 63-year-old in a Caucasian cadaveric specimen.

Simultaneous Posterior Femoral Cutaneous Nerve and Sciatic Nerve Variations: A Case Report.

During the routine dissection of a formalin fixed Caucasian cadaver, a previously unreported variation of the sacral plexus was found in the right gluteal region. The posterior femoral cutaneous nerve was found to pierce the piriformis muscle as opposed to running along its more common course below the muscle. At the same level of the posterior femoral cutaneous nerve, the common fibular nerve also pierced the piriformis muscle, while the tibial nerve passed inferior to the piriformis muscle.

Who really needs a Metaverse in anatomy education? A review with preliminary survey results.

The term Metaverse ("meta" defined as beyond, transcendence or virtuality, and "verse" meaning universe or world) denotes a "virtual reality space" for anatomy teaching. To ascertain how many anatomists are familiar or are using this adjunct in teaching, we conducted a short survey at the 2022 annual meeting of the American Association of Clinical Anatomists (AACA). Interestingly, only six respondents (9.

Intramedullary Spinal Cord Abscess with Concomitant Spinal Degenerative Diseases: A Case Report and Systematic Literature Review.

Intramedullary spinal cord abscess (ISCA) is a rare clinical pathology of the central nervous system that usually accompanies other underlying comorbidities. Traditionally it has been associated with significant mortality and neurological morbidities because it is often difficult to diagnose promptly, owing to its nonspecific clinical and neuroimaging features. The mortality rate and the outcome of these infections have been improved by the introduction into clinical practice of antibiotics, advanced neuroimaging modalities, and immediate surgery.

Spontaneous resolution of syringomyelia following pregnancy and parturition in a patient with type I chiari malformation: A case and systematic review.

Background: Spontaneous resolution of syringomyelia has rarely been reported in the literature. Rarer still are cases wherein this process is associated with pregnancy and parturition. We review theories on syringomyelia development and spontaneous resolution to better understand the role pregnancy and parturition may play in both processes.

An evaluation of mandibular canal variations: a systematic review and meta-analysis.

The inferior alveolar nerve and vessels are carried via the mandibular canal, which extends bilaterally from the inferior alveolar foramen to the mental foramen. Bifid and trifid mandibular canals result from abnormal fusions of nerve canals. The purpose of this study was to provide an up-to-date and comprehensive analysis of the prevalence of mandibular canal variations among healthy adults, and to identify any potential ethnic, sex, or laterality predilections.

Trifid and ventrally curved xiphoid process with two sternal foramina.

In this report, we present the case of a 56-year-old man with an asymptomatic, ventrally curved, trifid xiphoid process with two foramina found incidentally during a CT screening. The objective of this report is to advance the knowledge and recognition of such variations and to discuss the clinical relevance. The xiphoid process was trifid with two xiphoid foramina, one above the other, between the middle and right processes.

Diagnosis and Treatment of Acute Pancreatitis.

The pancreas is a glandular organ that is responsible for the proper functioning of the digestive and endocrine systems, and therefore, it affects the condition of the entire body. Consequently, it is important to effectively diagnose and treat diseases of this organ. According to clinicians, pancreatitis-a common disease affecting the pancreas-is one of the most complicated and demanding diseases of the abdomen.

What Is Currently Known about Intramedullary Spinal Cord Abscess among Children? A Concise Review.

Intramedullary spinal cord abscesses (ISCA) are rare. Typical symptoms include signs of infection and neurological deficits. Symptoms among (younger) children can be highly uncharacteristic.

Anatomical contribution of the orbicularis oculi to the zygomaticus major: An improved understanding of the smile with consideration for facial cosmetic procedures.

The aim of the present study was to determine the contribution of the orbicularis oculi (OOc) to the zygomaticus major (Zmj) in connecting the orbital region to the corner of the mouth. The OOc and Zmj of 22 embalmed adult Korean cadavers were dissected in 44 hemifaces. The OOc fibers were traced to determine their contribution to the Zmj.

Embryology of the Abdominal Wall and Associated Malformations-A Review.

In humans, the incidence of congenital defects of the intraembryonic celom and its associated structures has increased over recent decades. Surgical treatment of abdominal and diaphragmatic malformations resulting in congenital hernia requires deep knowledge of ventral body closure and the separation of the primary body cavities during embryogenesis. The correct development of both structures requires the coordinated and fine-tuned synergy of different anlagen, including a set of molecules governing those processes.

The Underlying Pathogenesis of Neurovascular Compression Syndromes: A Systematic Review.

Neurovascular compression syndromes (NVC) are challenging disorders resulting from the compression of cranial nerves at the root entry/exit zone. Clinically, we can distinguish the following NVC conditions: trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia. Also, rare cases of geniculate neuralgia and superior laryngeal neuralgia are reported.

A large sublingual glandular branch of the lingual nerve: a rare case report.

While the route, location, and pathology of the lingual nerve has been detailed extensively in reports in the literature, its terminal branch to the sublingual gland is often overlooked. It is known, via both gross and histological observation, that the sublingual glandular branch terminates at the posterior aspect of the sublingual gland. Upon routine cadaveric dissection of a male cadaver, one of the lingual nerve branches was found to terminate at the anteroinferior portion of a herniated sublingual gland.

Bilateral Coronal Synostosis and Mega Cisterna Magna: A Case Report.

Craniosynostosis is often associated with raised intracranial pressure (ICP), especially when multiple sutures are involved. In this report, we discuss an unusual association in a patient with craniosynostosis. We report a case of a two-year-old Caucasian male with bilateral coronal synostosis (BCS) who was found to have a concomitant mega cisterna magna (MCM).

Postprandial Referred Shoulder Pain: A Case Report.

The precise mechanism of referred pain is not well understood; however, diaphragmatic irritation is a well-known etiology of referred pain. Left side referred pain due to diaphragmatic irritation is most commonly attributed to splenic laceration i.e.

An unusual origin of a papillary muscle of the right ventricle.

Knowledge of anatomical variations of the heart are important to cardiac surgeons, cardiologists, and radiologist. During routine dissection of a 77-year-old male cadaver, we observed an unusual origin of a papillary muscle of the right ventricle arising from the atrioventricular aspect of the moderator band. This papillary muscle was 6.

Morphology of the groove of the inferior petrosal sinus: application to better understanding variations and surgery of the skull base.

Although adequate venous drainage from the cranium is imperative for maintaining normal intracranial pressure, the bony anatomy surrounding the inferior petrosal sinus and the potential for a compressive canal or tunnel has, to our knowledge, not been previously investigated. One hundred adult human skulls (200 sides) were observed and documented for the presence or absence of an inferior petrosal groove or canal. Measurements were made and a classification developed to help better understand their anatomy and discuss it in future reports.

Clinical significance of morphological variations of the inferior phrenic arteries.

The rapid development of sciences such as genetics and molecular biology offers hope that better therapeutic methods can be developed and diagnosis and treatment made more effective. However, we must not forget that the basis for understanding the complex mechanisms of diseases and associated symptoms is knowledge of the relevant location and correlation among organs. In the present study, we focus on the clinical significance of the inferior phrenic artery.
