Neural Loop by the Median Nerve’s Roots Associated with Multiple Neurovascular Anomalies: A Cadaver-based Case Report with Clinical Aspects

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.
