Abstract: Anterior cerebral artery is the smaller terminal branch of the internal carotid artery. It is one of the arteries involved in the formation of the arterial circle of Willis at the base of the brain. Its hypoplasia or absence can cause serious problems during neurosurgery or in the vascular dynamics of the brain. We found a rare variation of the right anterior cerebral artery during the dissection of the brain. The initial segment of the artery was hypoplastic and plexiform. The anterior communicating artery was absent. The right and left anterior cerebral arteries fused with each other for a distance of about 1 cm. The course, size and distribution of the distal part of the right anterior cerebral artery were normal. This case may be of special importance to neurosurgeonsand radiologists. Obstructionor rupture of the left anterior
cerebral artery in such cases might result in infarct of the medial surfaces of both cerebral hemispheres.

Abstract: We report here an anomalous origin and course of left colic artery in relation to pancreas during routine dissection of the abdominal region in a 70-year-old male cadaver in the department of anatomy. The anomalous left colic artery took its origin from the superior mesenteric artery and immediately divided into right and left branches. The right branch passed through the transverse mesocolon to supply the left one third of the transverse colon. The left branch traversed to the left along the inferior border of the body of the pancreas and crossed the left kidney before supplying the left colic flexure of colon and descending colon. This aberrant course of the left branch of the left colic artery can be considered as a “vulnerable” course as it is liable to injury during pancreatic and renal surgeries since the artery is not expected to run along the inferior border of the pancreas. The pancreas, a retroperitoneal organ, is related to major arteries such as abdominal aorta, inferior vena cava, coeliac trunk and its main branches, superior mesenteric vessels, splenic and portal veins. Surgery of the pancreas therefore, not only needs a thorough knowledge of the normal course of branches of these vessels but also demands a good knowledge of possible anomalous vessels arising in this region.
Unusual communication of profunda femoris vein with the popliteal vein in the middle of the popliteal fossa  [PDF]

Abstract: Profunda femoris vein (PFV) rarely forms a direct communication with the lower end of the femoral vein (FV) or popliteal vein (PV). During regular dissections for medical undergraduates, we came across a rare anatomical variation of PFV in the right lower limb of an 80-year-old female cadaver. PFV commenced from the PV just above its formation by the union of anterior and posterior tibial veins. It traversed the popliteal fossa on the lateral side of the popliteal artery and entered into the adductor canal after piercing the adductor magnus muscle. Finally, it emptied into the FV in the lower part of the femoral triangle. Furthermore, the PV had a small caliber than that of PFV. Deep veins of leg are the common site for formation of thrombosis. In terms of diagnosis and operative procedures, the location of thrombosis in the deep veins of lower limb is clinically of great importance. Thus detailed knowledge of the anatomical variation reported here is useful during diagnosis and treatment of deep vein thrombosis.

Abstract: Although the flexor pollicis longus is known to show the additional head of the origin, the occurrence of its additional tendons in the carpal tunnel are seldom reported. The presence of such additional tendons in the carpal tunnel cannot be overlooked during the radiological and surgical procedures in this region. Herein, we report a rare case of additional muscle belly of flexor pollicis longus. The additional muscle belly after a short course divided into three tendons. All three tendons entered the carpal tunnel along with flexor pollicis longus, passing deep to the flexor retinaculum. Within the carpal tunnel, two of these tendons fused and terminated by merging with the undersurface of the flexor retinaculum. The third tendon terminated by joining the flexor digitorum superficialis tendon for the index finger, in the palm. An additional slip of the first lumbrical muscle took origin from the third tendon of the additional muscle belly of flexor pollicis longus. Further, the embryological basis and clinical significance of current case is discussed.

Abstract: the communications between the branches of cervical plexus and cervical branch of facial nerve are common and are well known. however, this communication usually occurs between the transverse cervical nerve and cervical branch of facial nerve. during routine dissection classes for the medical undergraduate students, we came across an anatomical variant of anterior division of great auricular nerve. this variation was found in a 60-year-old male cadaver of south indian origin and it was unilateral. the great auricular nerve arose from the loop of ventral rami of c2 and c3 spinal nerves and divided into anterior and posterior branches. the anterior branch ran obliquely upwards and forwards on the surface of the sternocleidomastoid muscle along with the external jugular vein towards the apex of parotid gland and divided into many branches. one of these branches gave a communicating branch to cervical branch of facial nerve outside the parotid gland. nerve endings of the remaining branches were found to penetrate the interlobular septa and a few of them were seen deep in the gland along the ducts and near the vessels. the functional significance of anatomic variations of nerve endings in relation to ducts, thin vessels deep in the parotid gland, observed in the present case are yet to be evaluated.

Abstract: The communications between the branches of cervical plexus and cervical branch of facial nerve are common and are well known. However, this communication usually occurs between the transverse cervical nerve and cervical branch of facial nerve. During routine dissection classes for the Medical undergraduate students, we came across an anatomical variant of anterior division of great auricular nerve. This variation was found in a 60-year-old male cadaver of South Indian origin and it was unilateral. The great auricular nerve arose from the loop of ventral rami of C2 and C3 spinal nerves and divided into anterior and posterior branches. The anterior branch ran obliquely upwards and forwards on the surface of the sternocleidomastoid muscle along with the external jugular vein towards the apex of parotid gland and divided into many branches. One of these branches gave a communicating branch to cervical branch of facial nerve outside the parotid gland. Nerve endings of the remaining branches were found to penetrate the interlobular septa and a few of them were seen deep in the gland along the ducts and near the vessels. The functional significance of anatomic variations of nerve endings in relation to ducts, thin vessels deep in the parotid gland, observed in the present case are yet to be evaluated. Las comunicaciones entre los ramos del plexo cervical y ramo cervical del nervio facial son comunes y bien conocidos. Sin embargo, esta comunicación por lo general ocurre entre el nervio cervical transverso y el ramo cervical del nervio facial. Durante las clases de disección de rutina para los estudiantes de pregrado de medicina, nos encontramos con una variante anatómica de la división anterior del nervio auricular mayor, unilateral, en un cadáver de sexo masculino de 60 a os, del Sur de la India. El nervio auricular mayor se originó desde el bucle de los ramos ventrales de los nervios espinales C2 y C3, y dividió en ramos anterior y posterior. El ramo anterior se dirigió oblicuamente hacia arriba y adelante sobre la superficie del músculo esternocleidomastoideo junto con la vena yugular externa hacia el ápice de la glándula parótida y se dividió en numerosos ramos terminales. Uno de estos ramos dió un ramo comunicante al ramo cervical del nervio facial fuera de la glándula parótida. Las terminaciones nerviosas de los ramos restantes penetraron en los septos interlobulares. Algunos de éstos se observaron profundos en la glándula a lo largo de los conductos y cerca de los vasos. La importancia funcional de las variaciones anatómicas de las terminaciones nerviosa

In the present case we report a rare unusual origin of third head of the sternocleidomastoid muscle in a 60 year-old male cadaver. This additional head originated from the investing layer of cervical fascia in the roof of the subclavian triangle close to the clavicle and traversed obliquely upward, forward and fused with clavicular head. The insertion and nerve supply of the muscle was found to be normal. El origen anormal, presencia de una cabeza adicional y disposición en capas de fibras son las variaciones reportadas del músculo esternocleidomastoideo. En el presente estudio, se presenta un origen poco habitual de la tercera cabeza del músculo esternocleidomastoideo en un cadáver de sexo masculino de 60 a os. La cabeza supernumeraria se originaba en la lámina superficial de la fascia cervical en el techo del triángulo subclavio próximo de la clavícula y cruzaba oblicuamente hacia arriba y adelante para fusionarse con la cabeza clavicular. La inserción e inervación del músculo eran normales.
A Rare Variation in the Origin and Course of the Artery of Penis

Case Reports in Vascular Medicine , 2014, DOI: 10.1155/2014/193194
Abstract: Vascular variations of the penis are very rare. Awareness of its variations is of utmost importance to the urologists and radiologist dealing with the reconstruction or transplants of penis, erectile dysfunctions, and priapism. We report an extremely rare variation of the artery of the penis and discuss its clinical importance. The artery of the penis arose from a common arterial trunk from the left internal iliac artery. The common trunk also gave origin to the obturator and inferior vesical arteries. The artery of the penis coursed forward in the pelvis above the pelvic diaphragm and divided into deep and dorsal arteries of the penis just below the pubic symphysis. The internal pudendal artery was small and supplied the anal canal and musculature of the perineum. It also gave an artery to the bulb of the penis. 1. Introduction The artery of the penis is the distal continuation of the internal pudendal artery after the origin of its perineal branch. It runs anteriorly below or above the inferior fascia of urogenital diaphragm to reach the area just below the inferior pubic ligament, where it terminates by dividing into deep and dorsal arteries of the penis [1]. Artery of the penis may rarely arise directly from the internal iliac artery and continue as the deep artery of the penis when the dorsal artery of the penis is a branch of internal iliac artery or the inferior epigastric artery [2]. Knowledge of variations in the origin and course of the artery of the penis is important to radiologists, surgeons, and urologists. We report an extremely rare variation of the artery of the penis and to the best of our knowledge this is the first report on such a variation. The clinical and surgical implication of the variation is discussed. 2. Case Report During dissection classes for undergraduate medical students, a rare variation in the origin and course of the artery of the penis was noted. The variation was found in an adult male cadaver aged approximately 70 years. The left internal iliac artery did not divide into anterior and posterior divisions. The main trunk of the internal iliac artery gave iliolumbar, lateral sacral, superior gluteal, middle rectal, and superior vesical arteries. In addition to these arteries two common trunks arose from it. The first common trunk bifurcated into inferior gluteal and internal pudendal arteries, whereas the second common trunk gave two inferior vesical arteries, obturator artery, and the artery of penis (Figure 1). The artery of the penis coursed forwards between the bladder and lateral pelvic wall until the pubis.

Abstract: Though efficacy of Allergen Specific Immunotherapy (ASIT) has been proved in many studies, reports about success in clinical practice and under field conditions in alleviating the suffering or decreasing the morbidity in patients of Allergic Rhinitis are few. 260 patients of Allergic Rhinitis without coexisting diseases were included. Skin prick test was done on all patients. ASIT was initiated with common inhalant indoor allergens as per standard protocol and patients were assessed at the start and at 2 m, 6 m and 18 months of ASIT. ASIT was able to significantly reduce the symptom score in all the three groups namely sneezing, rhinorrhoea and nasal itching (p < 0.001). Concurrently it was also able to produce a significant reduction in the usage of concomitant drug intake (p < 0.001) thereby implying a decrease in morbidity. When assessed regarding clinical efficacy, ASIT was found to be satisfactory or highly effective in more than 75% patients. ASIT has got a role in clinical practice in polysensitized patients in field conditions. This is based on the evidence that besides decrease in hypersensitivity/symptoms, it also has an effect on minimizing the necessity of taking drugs to relieve the symptoms, which has strong implications of economics and toxicity, while treating patients.
