A man with leg pain and rash had polyradiculopathy, a nerve disorder. Infectious causes were identified through tests, leading to diagnosis and treatment.
Area of Science:
- Neurology
- Infectious Diseases
Background:
- Polyradiculopathy presents with diverse etiologies, encompassing structural and nonstructural causes.
- Differential diagnosis is crucial for identifying underlying conditions such as spinal stenosis, tumors, or infections.
Observation:
- A 68-year-old male presented with palmar rash, leg pain, and gait disturbance.
- Neurologic examination indicated a multi-root involvement, suggestive of polyradiculopathy.
Findings:
- The patient's presentation, particularly the palmar rash, prompted investigation into infectious etiologies.
- Serology and lumbar puncture confirmed an infectious cause for the polyradiculopathy.
Implications:
- This case highlights the importance of considering infectious etiologies in polyradiculopathy, especially with dermatologic manifestations.
- Prompt diagnosis and management of infectious polyradiculopathy can lead to significant patient improvement.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
