Diagnostic Techniques for Posterior Cutaneous Nerve Entrapment Syndrome

Area of Science:

• Neurology
• Pain Medicine
• Diagnostic Imaging

Background:

• Posterior cutaneous nerve entrapment syndrome (POCNES) is a challenging diagnosis.
• Accurate diagnosis often requires specific clinical evaluation beyond standard imaging.

Observation:

• A case report focusing on an older adult female patient with suspected POCNES.
• Clinical examination revealed localized back pain, pinpoint tenderness, and sensory abnormalities.
• A severe pain response to palpation of the tender point was noted.

Findings:

• Diagnostic criteria for POCNES include specific clinical features and normal imaging.
• A video demonstration captured key physical examination findings for POCNES diagnosis.
• Lidocaine injection at the tender point provided immediate diagnostic confirmation and pain relief.

Implications:

• Video demonstrations can serve as a valuable tool for clinicians diagnosing POCNES.
• This approach enhances diagnostic accuracy, especially in cases with inconclusive imaging.
• Improved diagnostic capabilities for POCNES can lead to more effective patient management.
