Nonrecurrent Laryngeal Nerve

We report the case of a patient submitted to a right hemithyroidectomy for a follicular adenoma, when we found a nonrecurrent laryngeal nerve. This is a really rare anatomical presentation that can seriously compromise the integrity and preservation of the inferior laryngeal nerve during thyroid surgery. We describe how we found and managed this anatomical variant and we conduct a review of the most recent Literature about nonrecurrent laryngeal nerve.

Sternalis Muscle

AbstractRectus sternalis muscle, either unilateral or bilateral is an uncommon anatomical variant among the anterior chest wall muscles. During the routine dissection as a part of undergraduate medical teaching in the department of Anatomy, a unilateral rectus sternalis muscle was noticed on the right hemi thorax in one cadaver, located adjacent to the sternum between the pectoralis major muscle and the superficial fascia of the region. Though rare in occurrence, when present, rectus sternalis muscle demands proper awareness and attention by the clinicians especially radiologists and surgeons, as the ignorance of the existence of this muscle may lead to misinterpretation, incorrect diagnosis and unnecessary clinical interventions. Such anatomical variations should be borne in mind while doing radiological investigations, radiotherapy and surgical procedures in the chest region.

Anatomical Variant

Background: Since its description in 1957, Couinaud`s classification of the segmental organization of the liver has remained valid. However, recent investigations by 3-dimensional computed tomography suggest a significant variability of the vascular anatomy and segment volume. Here, we report a surprise finding during the laparoscopic cholecystectomy of a patient with Conradi-Hünermann-Happle syndrome, in whom the liver segments were not fused. Case report: Laparoscopic cholecystectomy was performed because of recurrent biliary pancreatitis in a 47 year-old male patient, who had been diagnosed with Conradi-Hünermann-Happle syndrome. Upon direct view, the liver parenchyma appeared normal, but liver segments were separated and connected by fibrous bridges containing vascular structures, only. Since the hilar anatomy was unclear, an open cholecystectomy was performed without technical difficulties and the postoperative course was uneventful. Postoperatively, magnetic resonance imaging was performed, which revealed a trifurcation of the portal vein and a right bile duct draining into the left main duct. Intersegmental signal alterations corresponded to the fibrous bands seen during laparoscopy. Conclusions: The intraoperative findings of this case confirm the segmental organization of hepatic anatomy proposed by Couinaud. The first description of such an unusual anatomical variant in an extremely rare genetic disorder strongly suggests an association with the genetic background of the syndrome. The established abnormalities of cholesterol biosynthesis in patients with Conradi-Hünermann-Happle syndrome may well explain the observed liver anomaly, which is a novel phenotype of this syndrome. Based on this case, we suggest a potential involvement of the mutation in the emopamil-binding protein gene in liver development and regeneration.

Context: Ischemia of Percheron’s artery(PA) is a rare neurological occurrence that results in bilateral paramedian thalamic infarction that may affect the midbrain. Among the symptoms are altered mental status, vertical ocular palsy, and memory changes, as well as hemiplegia, cerebellar ataxia, and movement disorders. Objective: To elucidate a case of stroke of the mesencephalic trunk in an uncommon anatomical variant of the thalamus-perfurans arteries Method:Daily neurological and laboratory evaluation in addition to complementary examinations such as skull CT and skull MRI. We also performed a qualitative analysis of articles in Portuguese and English journals indexed in the following databases: PubMed (Public Medical Literature Analysis), Lilacs (Latin American and Caribbean Literature on Health Sciences) and Scielo (Scientific Eletronic Library Online). Case report: A 67 year old male presented with mild to moderate headache for 2 days, reporting chronic cough and decreased level of consciousness for 1 day. He was intubated (Glasgow 6) and sedated for diagnostic elucidation. The CT shows mild cerebral edema and MRI shows bilateral thalamic infarction affecting the PA. The clinical picture evolves to ischemic stroke of the mesencephalic trunk. Discussion: The bilateral infarction of the Percheron artery, as presented in this case, the neurological and neuropsychological manifestations are more severe such as akinetic mutism, thalamic dementia and loss of self psychic activation(Robot Syndrome). In these cases, the neuropsychological disturbance is best noticed when the patient regains consciousness. Conclusion: In the presence of a clinical presentation suggestive of bilateral thalamic infarction, the Percheron Syndrome hypothesis should be suspected.

Abstract Background Complex orthoplastic lower limb trauma in individuals with multiple injuries requires considerable resources and interdisciplinary collaboration for good outcomes. We present the first reported end-to-side free flap microanastomosis for lower limb trauma reconstruction involving a peronea arteria magna without radiographic collaterals. Case presentation A 55-year-old Caucasian gentleman involved in road traffic collision sustained an open tibial fracture on the anteromedial distal third of the left lower leg with local degloving and a subtotal right foot and ankle degloving. Both injuries were reconstructed with free tissue transfer. A left lower limb peronea arteria magna successfully received a free gracilis muscle flap by end-to-side microanastomosis and perfusion of the foot was preserved. This rare anatomical variant and its anatomy is reviewed, as well as a description of the suggested preoperative planning and technique for reconstruction. Conclusions Successful free flap reconstruction may be performed to a lower limb with a peronea arteria magna recipient as the lone vessel supplying the foot in trauma, although preoperative counseling of the risks, benefits, and options are essential.

Purpose: Variations in brachial plexus anatomy are common. As such, the knowledge of variations is essential for surgeons and anesthesiologists to decrease the risk of iatrogenic injuries. Moreover, brachial plexus variations often co-exist with aberrant vasculature. The median nerve is formed from contributions by the lateral and medial cords. This case report details a unique variant in the formation of the median nerve. Methods: The anatomical variant presented was identified during an upper-limb dissection of an adult cadaver.Results: The anatomical variant presented demonstrates a bifurcation of the middle trunk of the brachial plexus that coalesces to the radix of the median nerve. Although prior studies have demonstrated median nerve brachial plexus variations, the aforementioned variant arises directly from the middle trunk and communicates directly with the median nerve, while previously mentioned variants often connect to the medial or lateral cords. Conclusion: The communicating branch between the anterior division of the middle trunk and radix of the median nerve represents a unique and uncommon anatomical variation.
