A replaced right hepatic artery (rRHA) arising from the superior mesenteric artery and an interlobar parenchymal bridge over the sagittal fissure have been observed on a 64-year-old formalin-fixed male cadaver in the anatomy laboratory. As we have followed a detailed segmental anatomy, we encountered an arterial distribution of segment IV featuring a different pattern from the literature so far. According to our observations, the segment I is supplied by both left (LHA) and middle (MHA) hepatic arteries; the segments II and III are supplied by the LHA while the segment IV is supplied by both the MHA and rRHA. The segments V-VIII are supplied only by the rRHA. The case emphasizes the importance of arterial variations of liver in terms of the surgical procedures during the liver transplantation, hepatic resections, hepatic tumors, and etc. Our discussion focuses to the arterial supply of the segment IV and possible complications it may cause during/after the liver operations.

Objective: The aim of this research is to determine the frequency of surface anatomical variations of palmaris longus (PL) muscle in the population of North Cyprus and their association with gender, body side, and hand dominance. Materials and Methods: The presence of PL was determined in 1280 subjects (660 females and 620 males) using four testing methods; Schaeffer's test, the Thompson's test, Pushpakumar's test and the Bhattacharya's test. Where the presence of the PL could not be determined by any of these tests, palpation was performed as the final confirmatory test. Results: The overall frequency of absence was 17.4%. Female subjects showed a higher frequency of absence of 10.6% compared to males (6.8%). The absence was more likely to occur in the non-dominant hand. In those that had the PL, there were 28 (2.6%) cases of a split tendon and 3 cases (0.2%) of a laterally displaced tendon of the PL. Conclusion: The overall frequency of absence of PL in North Cyprus was 17.4% and absence is more likely to occur in females, on the left side and in the non-dominant hand. Other variations recorded are the split tendons and laterally displaced tendons.

We have come across a series of variations on our cadaver during routine dissection of the abdominal viscera. The amount and extent of the variations were unexpected in one cadaver, and they were followed one after another as listed: a peritoneal cyst formed by the parietal peritoneum that was stuck to the anterior surface of the right kidney, intraperitoneal duodenum, intraperitoneal ascending colon, partially constricted transverse colon, and several peritoneal strings running in between the various parts of the visceral peritoneum and the parietal peritoneum covering the abdominal wall, unusual location and size of the root of mesentery, and agenesis of the vermiform appendix. Our cadaver's medical history has not shown any surgery; it never showed any scars on the abdominal wall that might have indicated surgical operations. Peritoneal variations and agenesis of vermiform appendix are of great importance during diagnostic monitoring as well as surgical interventions. Extensive peritoneal variations in one patient may cause some extremely critical complications during the peritoneal dialysis, as well as during the laparoscopic approaches. We present these multiple and complex variations in one cadaver with respect to serious clinical complications that may come out because of ignorance of such cases.

This case is presented after a concurrent cavum septum pellucidum, cavum vergae, cavum velum interpositum, and a pineal cyst prevailed following a magnetic resonance imaging evaluation for a temporary blindness the patient reported that she recently had.
