Nerve Entrapments in the Pelvis and Hip

Area of Science:

• Radiology
• Neurology
• Anatomy

Background:

• Pelvic entrapment neuropathies present with nonspecific and variable clinical symptoms, complicating diagnosis and localization.
• Accurate diagnosis requires a thorough understanding of pelvic and hip nerve anatomy and imaging characteristics.

Purpose of the Study:

• To highlight the importance of magnetic resonance imaging (MRI), specifically MR neurography, in diagnosing pelvic and hip nerve entrapment neuropathies.
• To emphasize the role of anatomical knowledge in interpreting imaging findings for these conditions.

Main Methods:

• Review of clinical presentations of pelvic entrapment neuropathies.
• Application of magnetic resonance imaging (MRI) and MR neurography for evaluating pelvic and hip nerves.
• Correlation of imaging findings with anatomical structures of the lumbosacral plexus.

Main Results:

• MR neurography is increasingly vital for diagnosing entrapment neuropathies of the pelvic and hip nerves.
• Key nerves evaluated include the sciatic, gluteal, femoral, lateral femoral cutaneous, obturator, and pudendal nerves.
• Integration of clinical data with detailed anatomical and imaging assessment is essential.

Conclusions:

• MR neurography is a valuable tool for diagnosing pelvic and hip nerve entrapment neuropathies.
• A comprehensive approach combining clinical evaluation, anatomical knowledge, and advanced imaging is critical for accurate diagnosis.
