The gastrocnemius muscle forms the belly of calf muscles in the posterior compartment of the leg. This paper reports a four-headed gastrocnemius (named quadriceps gastrocnemius) muscle as a new variant and when present can alter the anatomy and/or the boundaries of the popliteal fossa. The four heads are named as medial, intermedio-medial,(More)
This paper reports two cases of cadaveric cystoduodenal ligament in the lesser omentum, different from the commonly known hepatoduodenal and hepatogastric ligaments. Cystoduodenal ligament was occasionally reported and implies a variation in the anatomy of the omental bursa and its foramen. The omental foramen which has been commonly described to provide(More)
Accessory peritoneal sac and cystoduodenal ligament as peritoneal variations were observed in a cadaver in our laboratory. Slender stomach, thin transverse colon, redundant sigmoid colon, absent ascending colon and doubly distended gall bladder were also reported in the same cadaver. Relevant anatomical and clinical implications are discussed.
Variant patterns of peritoneal folds could be formed due to the complex nature of the embryology of the peritoneum and the gastrointestinal tract. When uncommon peritoneal folds are formed, they could influence aberrant formation of surrounding gastrointestinal structures and create spaces that may harbour peritoneal fluids in cases of infection or(More)
We evaluated the morphological framework of the pes anserinus in both knees of ten Nigerian cadavers and we observed high degree of variability in its morphology and location. The pes anserinus inserted specifically on the superior half of the media border of the tibia, as far inferiorly as 124.44 mm to the tibial tuberosity (prolonged insertion). The(More)
