“…Neural loops are uncommon variants of nerves. Various neural loops concerning the formation of the median nerve (MN) have been documented without content or penetrated by arteries such as the superficial brachial artery [2]. The abnormal proximal division of the brachial artery gives rise to a so-called superficial brachial artery, an arterial variation that has an incident rate of 22% [3].…”

The existence of a combination of neural and vascular variations in the axilla and arm region are relatively common. In the current case study, an association of a neural loop by the roots of the left median nerve along with an ipsilateral proximal division of the brachial artery in the upper arm and bilateral communications between the median and musculocutaneous nerves is documented. The morphological features of these abnormalities, along with the clinical implications induced during nerve blocks and surgical interventions in the region, are discussed as well.
