Learning objectives The learning objectives of this poster are to enhance understanding of the brachial plexus anatomy including its common anatomical variants and to identify key pathological findings of the brachial plexus while highlighting the role of MR imaging for accurate diagnosis and clinical decision-making. 
Read more Background The brachial plexus is a complex anatomic structure that is essential for upper limb movement and sensation. Usage of anatomic landmarks helps in reliably identifying the various parts of the brachial plexus. MRI is a valuable diagnostic tool for detection and differentiation of the various plexus pathologies. This poster highlights the most common plexus pathologies. 
Read more Findings and procedure details Anatomy and normal variantsThe brachial plexus is a network of nerves that originates from the ventral rami of the C5 to T1 spinal nerves. These roots combine to form three trunks: the upper (C5-C6), middle (C7), and lower trunk (C8-T1). Each trunk divides into an anterior and posterior division, which merge to form three cords: the lateral, posterior, and medial cords. The cords give rise to the terminal branches, which include the musculocutaneous, axillary, radial, median, and ulnar nerve. They...
Read more Conclusion Understanding the anatomy of the brachial plexus and its common variants is essential for accurately identifying pathologies affecting this complex nerve network. Knowledge of the most common brachial plexus pathologies allows radiologists to recognize key imgaging features and to differentiate between conditions. Accurate diagnosis through MR imaging supports clinicians in determining appropriate treatment and therefore contributes to better patient outcomes.
