[Imaging of plexopathy].

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Peripheral nerve system imaging has advanced significantly with magnetic resonance imaging (MRI) technology.
• Plexopathy diagnosis traditionally relies on physical examination and electrodiagnostic studies, but imaging offers further insights.

Purpose of the Study:

• To explore the role of advanced imaging techniques in diagnosing and managing plexopathy.
• To highlight the utility of various imaging modalities for peripheral nerve system conditions.

Main Methods:

• High-resolution MRI is presented as a primary method, detailing its findings such as enlargement, T2 hyperintensity, and contrast enhancement.
• Complementary techniques including ultrasonography for entrapment syndromes and positron emission tomography (PET) for differentiating tumor recurrence are discussed.
• The use of postmyelographic tomography and MRI in posttraumatic brachial plexopathy is noted.

Main Results:

• High-resolution MRI reveals characteristic signs of plexopathy, including structural changes and muscle denervation.
• Ultrasonography and PET provide valuable complementary information for specific plexopathy subtypes.
• Imaging aids in differentiating various causes of plexopathy, such as traumatic injury, tumors, and entrapment syndromes.

Conclusions:

• Adequate imaging of brachial and lumbosacral plexuses is crucial for diagnosis.
• Imaging facilitates preoperative assessment, therapeutic planning, and patient follow-up for plexopathy.
• Advanced imaging techniques enhance the comprehensive evaluation of peripheral nerve system disorders.
