Radiographic evaluation of brachial plexopathy

Summary
Diagnosing brachial plexopathy requires tailored imaging. Trauma patients benefit from cervical myelography first, while non-trauma cases depend on clinical localization for initial CT or myelography.
Area of Science:
- Radiology
- Neurology
- Medical Imaging
Background:
- Brachial plexopathy diagnosis is challenging due to subtle or confusing neurologic signs.
- Accurate localization of brachial plexus disease is difficult.
- Optimal radiographic approaches are needed for diagnosis and anatomical delineation.
Purpose of the Study:
- To determine the most direct radiographic approach for diagnosing brachial plexopathy.
- To anatomically delineate the causes of brachial plexopathy.
- To compare imaging efficacy in traumatic versus non-traumatic cases.
Main Methods:
- Retrospective review of clinical and radiographic records of 43 patients with brachial plexus symptoms.
- Analysis of patients who underwent CT and/or myelography.
- Division of patients into traumatic and non-traumatic groups.
Main Results:
- Deficiencies in CT evaluation were noted in 35% of non-traumatic cases, delaying diagnosis.
- Trauma patients presenting with brachial plexus symptoms should undergo cervical myelography before CT.
- Non-traumatic patients require clinical classification (central vs. peripheral) to guide initial imaging (myelography for central, CT for peripheral).
Conclusions:
- Imaging strategy for brachial plexopathy should be tailored based on trauma history and clinical presentation.
- Cervical myelography is recommended as the initial imaging modality for traumatic brachial plexopathy.
- CT protocols should include contrast enhancement for improved visualization of vascular structures.
