Anatomical variations of duodenum such as atresia, stenosis and variations in shape have been described by various authors, but existence of gross anomaly in shape and position of midgut segment of duodenum is rare. Few reported cases of duodenal anomalies date back to early twentieth century. In wake of advancement of imaging techniques and minimal access surgeries, authors report a case of rare duodenal anomaly. The present case reports an anomaly of position of the midgut segment of the duodenum in an adult female cadaver. It was observed that the lower half of second part of duodenum was coiled like a serpent on the upper pole of right kidney. This part coursed initially upwards running parallel and to the right of the upper half of the second part of the duodenum. The third part coursed downwards and to the left, posterior to head and neck of pancreas, in its course sandwiching the commencement of portal vein. The reported case assumes significance because of possibility of misinterpretation of radiological images which will be discussed while citing such references.
Anatomical variations in the origin of the arteries in the abdominal area are very common. The arteries that show frequent variations include the celiac trunk, renal and gonadal arteries. During a routine dissection of a female cadaver, one main and one inferior right accessory renal artery were found in the abdominal region. We discovered that the inferior accessory renal artery that originated from the right anterior midline aspect of abdominal aorta was running into the lower pole of the right kidney. The origin of the main right renal artery was seen coming from the right anterolateral aspect respectively. The inferior accessory right renal artery ran directly into the inferior pole of the right kidney, in the area where the accessory right renal vein was leaving the right kidney. These anatomical variations and anomalies are important to know before any therapeutic or diagnostic procedures are performed in the abdominal area.

Radhika Andhra Medical College, Visakhapatnam, Andhra Pradesh, India Taenia solium commonly called as pork tapeworm is seen to infect people who consume measly pork (undercooked/pig infested with cysts of pork tapeworm). Neurocysticercosis is the clinical condition acquired by these larvae reaching the brain. It is one of the major causes for acquired seizures and epilepsy. CT and MRI imaging methods are a boon to such patients, as these are the most sensitive and specific diagnostic methods following which the clinical and surgical treatment has become most effective resulting in nearly complete care of these patients. A 42 yr old male presented with sudden seizures, followed by subsequent psychotic behavior to the neuromedicine department in KGH, Vizag, during our routine peripheral postings. MRI and CT imaging revealed extensive Neurocysticercosis and perilesional edema causing mass effect over the midline structures. The awareness and identification of various types of clinical and imaging of Neurocysticercosis is important because of the presence of the larva in a particular site of brain resulting in specific loss of that physiological activity can allow a neurosurgeon to identify and decide the treatment modality accordingly.

106 Origin of biceps brachii by three heads: A case report T. Ahmad Department of Anatomy, Faculty of Dentistry, Jamia Millia Islamia, New Delhi, India Biceps brachii is one of the most variable muscles of the human body generally originated by two heads namely long and short. The long head originates from the supraglenoid tubercle of scapula whereas the short head originates from the tip of the coracoids process of scapula. The muscle is reported to have several anatomical variations that might have clinical implications. The Anatomical variations already known include an additional third head arising from the humerus in 10% of cases (normal variation) but four, five, and even seven supernumerary heads have been reported in rare cases. Another variation includes the distal biceps tendons which are sometimes completely separated (40%) and at occasions are bifurcated (25%). In the present study of routine anatomical dissection of the left upper extremity of an adult Indian male cadaver, the biceps brachii muscle was found to have an abnormal origin by third head. This third head was found to take its origin along with the fibers of short head from the tip of the coracoids process. The third head was found to be inserted together with the other two heads of biceps brachii into the bicipital aponeurosis and the radial tuberosity. The third head also receives its nerve supply from the musculocutaneous nerve, as do the other two heads of biceps brachii. The knowledge of such variations is important during surgical corrections of the arm, from anatomical standpoint of view it can be presumed that the presence of a third head may increase the power of flexion and supination of the forearm.
