The teres major muscle originates on the dorsal aspect of the inferior angle and the lateral edge of the scapula, under the teres minor muscle.
Isolated lesions to the teres major muscle are rare.
Lesions of the teres major muscle are thus the result of different types of traumatism: trauma in traction with the upper limb stretched, during eccentric concentration of the muscle that opposes the sudden traction.
Thereafter, the axillary artery I continued as brachial artery I, distal to inferior border of teres major muscle. The brachial artery I coursed downwards along the medial side of the median nerve and was also superficial and tortuous.
At the lower border of teres major muscle, the axillary artery II continued as a brachial artery II.
Both these arteries traversed up to lower border of teres major muscle and continued as brachial artery I and brachial artery II.
Less severe lesions were seen in the tongue, temporal, diaphragm, psoas major and teres major muscles. Lung was congested, with mild thickening of the alveolar septa and focal to coalescent areas infiltrated by neutrophils, lymphocytes and rare epithelioid macrophages.
