Summary
A rare neurinoma tumor caused prolonged calf pseudohypertrophy and leg weakness over eight years. This unique case highlights an unusual association with neurogenic pseudohypertrophy.
Area of Science:
- Neurology
- Oncology
- Radiology
Background:
- Neurogenic pseudohypertrophy is a rare condition with diverse etiologies.
- Muscle hypertrophy can be associated with various neurological disorders.
Observation:
- A patient presented with eight years of left calf pseudohypertrophy, triceps suralis weakness, and intermittent foot pain.
- Later, mild weakness in the right anterior leg musculature developed.
Findings:
- Magnetic resonance imaging revealed an intraspinal, extraspinal tumor near the conus medullaris.
- Histological examination confirmed the tumor to be a neurinoma.
Implications:
- This case presents a novel association between neurinoma and neurogenic pseudohypertrophy.
- Further research may elucidate the mechanisms linking spinal tumors to muscle pseudohypertrophy.
