Ilioinguinal nerve is a collateral branch of lumbar plexus. Its anatomical variations in relation to adjacent musculoaponeurotic structures play a crucial role in the development of neuropathies associated with lower abdominal surgeries. In this report, we present a rare case of unusual course and branches of the ilioinguinal nerve, in a 55-year-old male cadaver. In the lateral part of inguinal canal ilioinguinal nerve gave three branches. Two of its branches pierced the external oblique aponeurosis, about 6 cm above the pubic symphysis, to supply the skin of the lower part of the anterior abdominal wall. Another branch pierced the conjoint tendon, in the medial part of the inguinal canal about 2 cm above the superficial inguinal ring. Knowledge of unusual path of these branches may be important to avoid injuries during the surgical repair of groin hernias. Further care should be taken while dealing with the conjoint tendon in the Bassini procedure.

Variant anatomy of muscles and veins of the neck is of importance to plastic surgeons, radiologists and general surgeons. We report the variations of sternocleidomastoid muscle and veins of the neck in the present article. Right sternocleidomastoid muscle had three heads of origin. The third head took its origin from the clavicle just lateral to the usual clavicular head. All the three heads were about 4 inches long and united with each other at the level of thyroid cartilage. There was no external jugular vein on the right side. The retromandibular vein united with facial vein to form common facial vein. Common facial vein joined with superior thyroid and lingual veins to form a thyrolinguo-facial trunk one inch below the angle of mandible. This trunk was about 2 inches long and terminated into the internal jugular vein. Knowledge of this case could be useful while raising a sternocleidomastoid flap, administering anesthesia to brachial plexus, neck surgeries and carotid endarterectomy.

Knowledge of anatomic variants of veins in the arm and axilla play a key role in planning of successful venous access. Possible anatomic variants of axillary vein, brachial vein and basilic vein and their clinical implications have been well described in the literature. We report a rare case of formation of a short axillary vein associated with complex venous communications between the basilic and brachial veins forming a venous ladder in the axilla, in formalin embalmed male cadaver. Axillary vein was formed in the upper part of the axilla by the fusion of basilic vein and unpaired brachial vein, and it was about 3cm in length. The higher-up confluence of basilic and brachial veins was also associated with presence of three communicating veins between the basilic and brachial veins in the axilla. Knowledge of reported venous variations is very useful during preoperative venous mapping and also for planning and execution of various surgical invasive procedures involving these veins.
