MR Imaging of the Orbital Apex
J Korean Radiol Soc 2000;4 :26 9-0 6 1 6 MR Imaging of the Orbital Apex: An a to m y and Pat h o l o g y 1 Ho Kyu Lee, M.D., Chang Jin Kim, M.D.2, Hyosook Ahn, M.D.3, Ji Hoon Shin, M.D., Choong Gon Choi, M.D., Dae Chul Suh, M.D. The apex of the orbit is basically formed by the optic canal, the superior orbital fis- su r e , and their contents. Space-occupying lesions in this area can result in clinical d- eficits caused by compression of the optic nerve or extraocular muscles. Even vas c u l a r changes in the cavernous sinus can produce a direct mass effect and affect the orbit ap e x. When pathologic changes in this region is suspected, contrast-enhanced MR imaging with fat saturation is very useful. According to the anatomic regions from which the lesions arise, they can be classi- fied as belonging to one of five groups; lesions of the optic nerve-sheath complex, of the conal and intraconal spaces, of the extraconal space and bony orbit, of the cav- ernous sinus or diffuse. The characteristic MR findings of various orbital lesions will be described in this paper.

Splenic vein thrombosis is a relatively common finding in pancreatitis. Gastric variceal bleeding is a life-threatening complication of splenic vein thrombosis, resulting from increased blood flow to short gastric vein. Traditionally, splenectomy is considered the treatment of choice. However, surgery in necrotizing pancreatitis is dangerous, because of severe inflammation, adhesion, and bleeding tendency. In the Warshaw operation, gastric variceal bleeding is rare, even though splenic vein is resected. Because the splenic artery is also resected, blood flow to short gastric vein is not increased problematically. Herein, we report a case of gastric variceal bleeding secondary to splenic vein thrombosis complicated by necrotizing pancreatitis successfully treated with splenic artery embolization. Splenic artery embolization could be the best treatment option for gastric variceal bleeding when splenectomy is difficult such as in case associated with severe acute pancreatitis or associated with severe adhesion or in patients withhigh operation risk. -

The Evolution of the Lepilemuridae-Cheirogaleidae Clade

Kerley April 2019 1 i Dedication To my mothers’ Cecelia Andrews & Johanna Cloete ii DECLARATION FULL NAME: Curswan Allan Andrews STUDENT NUMBER: 214372952 QUALIFICATION: Doctor of Philosophy DECLARATION: In accordance with Rule G5.6.3, I hereby declare that the above-mentioned thesis is my own work and that it has not previously been submitted for assessment to another University or for another qualification. Signature ________________ Curswan Andrews iii ABSTRACT The Lepilemuridae and the Cheirogaleidae, according to recent molecular reconstructions, share a more recent common ancestor than previously thought. Further phylogenetic reconstructions have indicated that body size evolution in this clade was marked by repeated dwarfing events that coincided with changes in the environment. I aimed to investigate the morphological implications of changes in body size within the Lepilemur-cheirogaleid clade, testing four predictions. Together with Dr. Couette, I collected data on the overall palate shape and predicted that shape is likely to be influenced by several factors including phylogeny, body size and diet. Geometric morphometric analyses revealed that, although a strong phylogenetic signal was detected, diet had the major effect on palate shape. In a similar vein, when examining the arterial circulation patterns in these taxa, I predicted that changes in body size would result in changes and possible reductions in arterial size, particularly the internal carotid artery (ICA) and stapedial artery (SA). -

Injection Into the Longus Colli Muscle Via the Thyroid Gland
Freely available online Case Reports Injection into the Longus Colli Muscle via the Thyroid Gland Małgorzata Tyślerowicz1* & Wolfgang H. Jost2 1Department of Neurophysiology, Copernicus Memorial Hospital, Łódź, PL, 2Parkinson-Klinik Ortenau, Wolfach, DE Abstract Background: Anterior forms of cervical dystonia are considered to be the most difficult to treat because of the deep cervical muscles that can be involved. Case Report: We report the case of a woman with cervical dystonia who presented with anterior sagittal shift, which required injections through the longus colli muscle to obtain a satisfactory outcome. The approach via the thyroid gland was chosen. Discussion: The longus colli muscle can be injected under electromyography (EMG), computed tomography (CT), ultrasonography (US), or endoscopy guidance. We recommend using both ultrasonography and electromyography guidance as excellent complementary techniques for injection at the C5-C6 level.

Tentorium Cerebelli: the Bridge Between the Central and Peripheral Nervous System, Part 2

Cardiology, Foundation Don Carlo Gnocchi, Milan, ITA 2. Osteopathy, French-Italian School of Osteopathy, Pisa, ITA 3. Radiology, IRCCS Fondazione Don Carlo Gnocchi Onlus, Milan, ITA Corresponding author: Bruno Bordoni, [email protected] Abstract The tentorium cerebelli is a meningeal portion in relation to the skull, the nervous system, and the cervical tract. In this second part, the article discusses the systematic tentorial relationships, such as the central and cervical neurological connections, the venous circulation and highlights possible clinical alterations that could cause pain. To understand the function of anatomy, we should always remember that every area of the human body is never a segment, but a functional continuum. Categories: Physical Medicine & Rehabilitation, Anatomy, Osteopathic Medicine Keywords: tentorium cerebelli, fascia, pain, venous circulation, neurological connections, cranio Introduction And Background Cervical neurological connections The ansa cervicalis characterizes the first cervical roots and connects all anterior cervical nerve exits with the inferior floor of the oral cavity, the trigeminal system, the respiratory control system, and the sympathetic system. The descending branch of the hypoglossal nerve anastomoses with C1, forming the ansa hypoglossi or ansa cervicalis superior [1]. The inferior root of the ansa cervicalis, also known as descendens cervicalis, is formed by ascendant fibers from spinal nerves C2-C3 and occasionally fibers C4, lying anteriorly to the common carotid artery (it passes laterally or medially to the internal jugular vein upon anatomical variations) [1]. -

The observations were made during routine laboratory dissections. In our 80- • Sternomastoideus some years of cumulative human dissection education prior to this detection, this was the first observation (with about 45 cadavers dissected yearly) of this muscle. The levator claviculae muscle was observed with intact nerve supply from the ventral ramus of C3, indicating its functional status. The muscle was lambda (λ)-shaped with its stem oriented cranially, attaching to the fascia of the longus capitis muscle at the level of the transverse process of the fourth cervical vertebra. More inferiorly, the stem splits into a pars medialis and pars lateralis each with fascial attachments to the clavicle within the middle third of the bone. Both parts had fascial attachments to the clavicle within the middle third of the bone, and the lateral part passed medial to the external jugular vein.
