Abstract
The median nerve is a mixed sensory and motor nerve that innervates part of the
flexor muscles in the anterior compartment of the forearm and muscles in the lateral
part of the hand; palmar cutaneous and digital cutaneous nerves branch from the median
nerve, which provides sensory innervation to the skin on the radial side of the palm.
Also, the median nerve is an object of interest because neuropathy of the median nerve
at the level of the carpal tunnel is the most common entrapment neuropathy which
increases dramatically in patients with diabetes. Neuromuscular ultrasound provides
extensive diagnostic information and has proved itself as a useful complementary test to
electrodiagnostic examinations in cases involving median nerve neuropathy. It often
happens that the cause of nerve entrapment and neuropathy are variants of several
anatomical structures along the course of the median nerve. It is important to be aware
and report such anatomical variations of the median nerve in order to avoid damaging the
nerve during surgical treatment. Despite the frequently documented abnormalities in the
pathway of the brachial plexus and the median nerve, the anatomical variations are
unusual to see and are rarely reported. Moreover, there are variations that do not fit
under any of the classifications described in the literature.
