Brachial plexopathies presents with symptoms that are difficult to diagnose because of complex anatomy and variety of lesions. Precise diagnosis is imperative for prognostic, surgical, and rehabilitative purposes. MRI having excellent multiplanar imaging capability and contrast resolution plays promising role in its evaluation. The present study was conducted with 30 patients clinically suspected of brachial plexopathies, selected and scanned using 1.5 Tesla MRI scanner. Out of 30 patients, 18 (60%) were traumatic and 12 (40%) were non traumatic lesions. Amongst traumatic, post–ganglionic injuries (70%) were common than pre–ganglionic (30%). Stretch injury (66.6%) was most common traumatic lesion, followed by root avulsion and psuedomeningocele in (22%) cases. Secondary tumors in 5 cases (41.6%) were most common cause of non– traumatic lesions, followed by primary tumors in 3 cases (25%). MRI is valuable in identifying, localizing, differentiating and characterizing various lesions which is critical for decision making and surgical planning.
