title: Crucial neurovascular structures entrapped in a brachial intramuscular tunnel.
abstract: We report a case where the median nerve accompanied by brachial vessels were found to traverse an intra-muscular tunnel within the brachialis muscle, in the floor of the cubital fossa. The muscular tunnel commenced 5 cm proximal to the neck of radius, measured 4.4 cm in length, and was present unilaterally. This unusual tunnel was distally found to blend with the brachial fascia. The present study was planned with an endeavor to elucidate in an improved way the clinical implications of compressed median nerve and brachial vessels. There are several sites where median nerve maybe compressed along its course in the arm and forearm. The relevance of the present documentation lies in the fact that these vital neurovascular structures may be compressed leading to neuropathies and vascular changes.
