Multimodality imaging review of ulnar nerve pathologies.

Area of Science:

• Neurology
• Radiology
• Nerve Imaging

Background:

• Ulnar neuropathy is the second most common nerve entrapment after median nerve issues.
• Clinical and electrodiagnostic methods are standard, but imaging is advancing management.
• Understanding normal ulnar nerve anatomy is key to diagnosing pathology.

Purpose of the Study:

• To highlight the role of advanced imaging in evaluating ulnar neuropathy.
• To discuss key anatomical sites prone to ulnar nerve compression.
• To review conditions predisposing to ulnar neuropathy.

Main Methods:

• High-resolution ultrasonography for dynamic evaluation.
• Magnetic Resonance Imaging (MRI) for superior resolution.
• Review of anatomical sites like cubital tunnel and Guyon's canal.

Main Results:

• Imaging aids in differentiating normal nerves from pathological conditions.
• MRI is considered more reliable than ultrasonography for detailed assessment.
• Various conditions, including tumors and inflammatory diseases, can cause ulnar neuropathy.

Conclusions:

• Advanced imaging, particularly MRI, is crucial for diagnosing and managing ulnar neuropathy.
• High-resolution ultrasonography is valuable for initial and dynamic assessments.
• Emerging techniques show promise but are not yet standard practice.
