“…So the diaphragmatic sulci is indicative of the surface projection of portal fissure and also represent the hepatic veins with their tributaries passing through them. 10 In our study, we observed in 2.9% of specimens the diaphragmatic sulci on the superior surface of right lobe extending to the anterior surface as compared to 7.5% observed by chaudhari et al…”

Liver is a wedge shaped visceral organ in the body, occupies right hypochondrium, epigastric region and extends in to left hypochondrium. A thorough knowledge of anatomy of liver and its variations will avoid errors in diagnostic imaging and will also help the surgeons design appropriate surgical approaches. Materials and Methods: The study was conducted in the Department of Anatomy of our Institution. A total of 35 numbers of livers removed from cadavers were used for the study. The morphological variations of liver such as changes in size, shape, presence of accessory lobes, fissures, hypoplastic lobes were noted and tabulated. Results: Out of the 35 livers studied, 15 specimens (42.9%) exhibited normal fissures and lobes, 13 (37.1%) had accessory fissures over different lobes. In 3(8.6%) specimens of liver hypoplastic left lobe was observed and in 4(11.4%) specimens lingular process of left lobe was observed. There were 8 accessory fissures were seen in right lobe, 5 in left lobe, 4 in caudate lobe and 5 in quadrate lobe. Out of 35 livers studied, accessory lobes were observed in 9 liver specimens, which can be grouped as 1 in right lobe, 2 in left lobe, 5 in caudate lobe and 1 in quadrate lobe. Conclusion:The authors conclude that morphological variations of liver must be taken in to account by the Radiologist and G a stroenterologist while making various differential diagno sis as these variations can present various clinical manifestations/ implications.

“…Type IV variants were the most common morphologic variants in our population. These variations have been reported with various names applied to them, such as pons hepatis [5][6]14,16,18,[21][22], absent fissure for ligamentum teres [9,12,17] and ligamentum teres tunnel [10][11]15,19]. We propose the use of standardized nomenclature and classifications, possibly those proposed within this paper.…”

BackgroundIn the classic descriptions of the human liver, the umbilical fissure (UF) is a long, narrow groove on the visceral surface that receives the ligamentum teres hepatis. In this study, we document the UF variations encountered in a series of cadaveric dissections. MethodsWe reported UF variations using the following classification: Type I refers to "normal" anatomy where there is a long, narrow groove. In type II, the UF was covered by a fibrotic band devoid of hepatic parenchyma. In type III variants, an extension of hepatic parenchyma partially covered but did not obliterate the UF. In type IV variants, the hepatic parenchyma formed a bridge over the UF, completely obliterating the groove. After institutional review board approval, we observed all consecutive cadaveric dissections over five years and recorded the characteristics and dimensions of each UF and its immediate relations. ResultsThere were 69 cadavers, and variant UFs were present in 38 (55.1%) cadavers: type II (1.5%), type III (20.3%), and type IV (33.3%). ConclusionsIn this Jamaican population, only 44.9% of persons had conventional "normal" anatomy and 55.1% had UF variants. These variants are clinically significant, as they lead to misinterpretation of patient imaging and can hinder operative procedures on the liver.

“…One of the abnormalities reported several times is Riedel’s lobe [8], defined as a downward tongue-like projection of the anterior edge of the right liver lobe to the right of the gallbladder. The accessory lobes may be attached to the liver through a mesentery or a bridge of the hepatic tissue and are usually asymptomatic [1, 7, 9, 10].…”

“…Anomalies of descent include cryptorchidism (anorchism, monorchism, and partially descended testis), ectopic testis, and persistence of processus vaginalis and encysted hydrocele of the spermatic cord [1]. The incidence of testicular cancer in patients with cryptorchidism is estimated to be 3 to 5 times higher than in the general population [10].…”

The occurrence of an additional (accessory) lobe of liver and undescended testis in a single cadaver: a case report

BackgroundAnatomical variations are common, some of these variations are clinically important and some are not. These variations may require treatment or they may be a variant of a normal presentation. In clinical practices, anatomical variations should not be overlooked. Anatomical variations may cause a tendency to some diseases, and may affect the symptoms, diagnosis and the course of disease. The main objective of this case report is to present the occurrence of two variations observed in a single cadaver. Even though there are reports of individual cases, these combined variations have not been reported before. There is also no evidence of developmental (embryological) circumstances for the liver anomaly to be associated with an undescended testis (cryptorchidism) and vice versa; therefore, this case is, by far, a coincidence.Case presentationThe two anatomical variations were noticed in an unclaimed male cadaver used for routine teaching and learning purposes. The Amhara male cadaver was approximate 41-year-old and his clinical history, family history, and other details were unknown. In the first incident, unusually the cadaver’s liver consisted of one additional (accessory) lobe situated on the visceral surface of the liver. In the second incident, an undescended testis was observed on the right side near to the superficial inguinal ring.ConclusionsOverall, knowledge of the above-mentioned anatomical variations has clinical significance to students, researchers, clinicians, surgeons, and radiologists who interpret plain and computed imaging.
