and ulnar nerves of the upper limbs may be affected by various peripheral neuropathies.
Although clinical examination and electrophysiologic testing are the most common diagnostic tools,
in certain cases ultrasound and magnetic resonance (MR) imaging and may provide key information about the exact anatomic location of a lesion or may be help narrow the differential diagnosis. The selection of the imaging modality to be used for further work-up for peripheral neuropathies...

BRACHIAL PLEXUS INTRODUCTION Brachial plexus is the main sensory and motor innervation of the upper extremity.
It may be involved in a variety of traumatic and nontraumatic pathologies.
Brachial plexus injury (BPI) is the most severe nerve injury of the extremities,
resulting in functional impairment of the upper limb. Various space-occupying lesions,
such as hematoma,
nerve sheath tumors,
primary or secondary tumors of perineural spaces,
and various tumor variants (diffuse...
A great variety of peripheral neuropathies affect the upper limbs and although clinical examination with electrophysiology studies remain the cornerstone of the diagnostic work-up,
in certain cases ultrasound and MR imaging may be establish the origins of the condition and provide important information for management or surgical planning.
