Knowledge of variations of renal vessels is of utmost importance in retroperitoneal surgeries and kidney transplant surgeries. We report concurrent variations of the right renal vessels, observed in an adult male cadaver during dissection classes. The right kidney was supplied by three renal arteries, out of which two entered the kidney through the hilum and the other one entered through the lower pole of the kidney. There were five renal veins, emerging independently from the hilum and opening separately through five openings into the inferior vena cava. Among the veins, only one emerged anterior to the renal pelvis and the other four emerged behind it. Four of them terminated into the posterolateral aspect of the inferior vena cava, whereas one terminated into its anterior aspect. Fourth vein from above, received the right testicular vein. The renal hilum was clogged with the presence of seven vessels and renal pelvis.

Anomalies of the peritoneum and the colon are quite common. Some of these anomalies can disturb the normal digestive and absorptive functions of the intestine and the others might result in formation of volvulus or impede the blood supply of the intestine. We report a rare, combined variation of peritoneum and ascending colon. In a 70-year-old male cadaver, the greater omentum was very small and extended only for about an inch below the transverse colon. From its lower end, a fibrous band extended to the right wall of the upper part of ascending colon. There was a deep constriction on the right wall of the ascending colon at the site of attachment of the fibrous band. The ascending colon was grossly dilated. Further, the ascending colon was mobile and presented a small ascending mesocolon along its left edge. We discuss the possible embryological basis and clinical and surgical relevance of the case.
A peculiar liver with surgically and radiologically important variations: a case report

A peculiar liver was found in an adult male cadaver during a dissection class for undergraduate medical students. Th e quadrate lobe and fi ssure for the ligamentum teres were totally absent. Th us, the cystic notch on the inferior border was very broad and deep, and the fundus and body of the gall bladder popped out through this notch. Th e cystic duct terminated into the right hepatic duct at the porta hepatis instead of terminating into the common hepatic duct. Awareness of variations of the lobes and fi ssures may minimize a misdiagnosis of liver problems. Th e aim of the current study was to alert radiologists and surgeons about possible variations in the external appearance and anomalies of the lobes and fi ssures of the liver.
Mylohyoid foramen of mandible: a rare exit point of intra-mandibular origin of nerve to mylohyoid
Satheesha B,Nayak,K.V. Soumya 대한해부학회 2020 Anatomy & Cell Biology Vol.53 No.1
Nerve to mylohyoid is a branch of inferior alveolar nerve. It arises in the infratemporal fossa and runs in the mylohyoid groove of mandible to reach the submandibular region, where it supplies the anterior belly of digastric and mylohyoid muscles. Though sensory distribution of this nerve have been described, it is predominantly a motor nerve. Here, a rare intra-mandibular origin of nerve to mylohyoid has been presented. This nerve arose from the inferior alveolar nerve inside the mandible and came out to the submandibular region by passing through a small foramen present on the medial surface of the body of the mandible. It ended by supplying the anterior belly of digastric and mylohyoid muscles. The knowledge of this variation could be of importance to maxillofacial surgeons and radiologists.

Atrial septal defect (ASD) is one of the common congenital anomalies of the heart in humans. Its complications depend on the size of the defect and can manifest at any age. The common symptoms of ASD include dyspnea and fatigue. Most of the ASDs are associated with morbidity and mortality, Earlier the treatment, it is better to the patient. I saw a large ostium secundum defect in the heart of an adult female cadaver during dissection classes for undergraduate medical students. The interatrial septum had large defect at the region where fossa ovalis should have been located. It was about 1.25 inches in diameter and oval in shape. This type of large septal defect might result in cyanosis, stroke or death of the patient at any age.
Partial duplication of tentorium cerebelli and complete duplication of falx cerebelli
Satheesha B. Nayak,Surekha D. Shetty 대한해부학회 2019 Anatomy & Cell Biology Vol.52 No.3
Variations of the dural folds and the dural venous sinuses are infrequently reported in the existing medical literature. Such variations in the posterior cranial fossa may pose difficulties in various analytical and surgical procedures of this region. We present a rare concurrent variation of the falx cerebelli and tentorium cerebelli that was detected during routine dissection of an adult male cadaver. While removing the brain, a partial duplication of tentorium cerebelli was observed below the left half of the tentorium cerebelli and above the left cerebellar hemisphere. This fold did not have any dural venous sinus in it. Further, a complete duplication of falx cerebelli with a single occipital venous sinus within its attached border was also observed. We present the review of literature and discuss the comparative anatomy of this case.
A rare additional lobe of cerebellum, projecting from its superior surface

Human cerebellum plays a vital role in motor coordination, regulation of muscle tone and maintaining the equilibrium of the body. It seldom shows anatomical/morphological variations. Herein, we report the presence of a small additional lobe projecting out on the superior surface of the right cerebellar hemisphere in the para-vermal area in an adult male cadaver. There was a notch on the tentorial surface of the occipital lobe of the right cerebral hemisphere, corresponding to the additional lobe of cerebellum. The additional lobe was histologically normal, with no evidence of any tumour cells. Knowledge of this variation is of importance to radiologists, neuroanatomists and neurosurgeons.

In this report, four unusual communications between external and internal iliac veins of the left side have been presented. The lowest communication was the narrowest measuring about 2 mm in diameter, the second measured 6 mm, the third had a diameter of 7 mm and the last communication measured 5 mm in breadth. The upper three communications were twisted in a helical manner. The internal iliac vein had its normal tributaries except that the iliolumbar vein drained into the external iliac vein at the level of the third communication. The external iliac vein was slightly dilated just below the level of lowest communication.

Surgical and radiological importance of a rare cysto-duodeno-colic peritoneal fold

It is quite common to see abnormal peritoneal folds in the abdominal cavity. Some of them might compress or strangulate the viscera and others might determine the direction of the flow of peritoneal fluid, pus or blood. Many unusual clinically important peritoneal folds such as Ladd’s band, cysto-gastro-colic fold, omento-cystic fold, and cysto-colic fold have been reported earlier. Knowledge of these folds is important for radiologists, gastroenterologists, and surgeons. We report an unusual cysto-duodeno-colic fold observed during our dissection classes. The fold was seen to compress the duodenum and colon. The fold extended from the descending part of the duodenum and the transverse colon to the gallbladder. It enclosed the entire gallbladder. A case similar to this has not been reported yet. It is important for the gastroenterologists and laparoscopic surgeons to be aware of this fold to avoid misdiagnosis and iatrogenic injuries.
