SUMMARY:With advancement in 3D imaging, better fat-suppression techniques, and superior coil designs for MR imaging and the increasing availability and use of 3T magnets, the visualization of the complexity of the brachial plexus has become facile. The relevant imaging findings are described for normal and pathologic conditions of the brachial plexus. These radiologic findings are supported by clinical and/or EMG/surgical data, and corresponding high-resolution MR neurography images are illustrated. Because the brachial plexus can be affected by a plethora of pathologies, resulting in often serious and disabling complications, a better radiologic insight has great potential in aiding physicians in rendering superior services to patients.

“…This opens a window of opportunity to obtain detailed assessment of muscle mass in individuals, thereby considerably expanding the topographical diagnosis. This technique has been successfully used to determine the extent of secondary muscle changes in multi-focal inflammatory nerve lesions such as in neuralgic amyotrophy [5] and in primary inflammatory myopathies [6]. It allows the recognition of the total extent of inflammation in multifocal diseases by revealing multiple muscle groups not seen with standard protocols.…”

Magnetic resonance imaging supplements investigations for the differential diagnosis of neuromuscular diseases. An advantage over routine neurophysiological or histopathological methods is that they are operator-independent, non-invasive and painless. Magnetic resonance imaging also has the advantage of providing a lasting detailed topographical picture of regional variations and allows robust measurements of muscle volume and various functional parameters.

“…Having decided upon a possible diagnosis of PTS, MRI imaging can be of use in ruling out alternative pathologies, including shoulder pathology or extrinsic nerve compression. 11 MRI also has the ability to directly support a diagnosis of PTS by documenting abnormalities suggestive of denervation, including edema, atrophy, and wasting in affected shoulder girdle muscles. 13 Electrophysiology studies may demonstrate different findings depending on the underlying pathology, conduction block, demyelination, or Wallerian degeneration that may occur in varying combinations.…”

Background: Parsonage-Turner Syndrome (PTS) is a rare but serious condition characterized by spontaneous paresis of the upper extremity, typically lasting several months with variable recovery. With little literature on the behavior of PTS from a hand surgeon's perspective, accurate diagnosis and subsequent counseling of patients with PTS can be challenging. Methods: This study is a retrospective evaluation of the clinical features of all PTS patients seen over a 9-year period. Data was collected for gender, side affected, handedness, inciting event, clinical presentation, nerve involvement, time taken for recovery, and extent of recovery. Results: Thirty-eight adult cases of PTS were identified, representing an incidence of 0.34 per 1000. Fifty-five percent were female, with predomination of right handedness and dominant upper extremity involvement (60% and 58%, respectively). There was an inciting incident identified in 42% of cases, and 37% of these involved surgery. Twenty-nine percent of cases presented without experiencing typical neuropathic pain. There was a predomination of anterior interosseous nerve (AIN) or posterior interosseous nerve (PIN) involvement (42% overall). Only 44% of patients achieved a complete recovery, taking a mean duration of 10 months. Conclusions: This study highlights both the rarity and atypical spectrum of clinical presentation of PTS, especially considering the more common involvement found for AIN and PIN. This highlights the likelihood that patients presenting with PTS to a hand surgical practice may differ from those typically described in the literature. The poor rate of recovery is in line with other recent reports and contrasts with the more positive outcomes found in earlier studies.
