Ultrasound Imaging for a Rare Cause of Sciatica: A Schwannoma of the Sciatic Nerve
Sciatica is a common musculoskeletal complaint, but it is rarely attributed to peripheral nerve tumors. Until now, there is little literature reporting sciatica caused by a sciatic schwannoma at the proximal thigh. A 27-year-old male had left posterior proximal thigh pain for more than two years. Co...

Sumario: | Sciatica is a common musculoskeletal complaint, but it is rarely attributed to peripheral nerve tumors. Until now, there is little literature reporting sciatica caused by a sciatic schwannoma at the proximal thigh. A 27-year-old male had left posterior proximal thigh pain for more than two years. Compression of the tender point caused numbness radiating to his low back, buttock and leg regions. Due to poor response to conservative treatments, he was referred for an ultrasound examination, which revealed a solid mass on the track of the sciatic nerve. The subsequent magnetic resonance imaging showed a well-defined tumor sized 2.3 × 1.8 × 2.3 cm beside the sciatic nerve, and a schwannoma was confirmed by postsurgical pathology. In conclusion, ultrasound is helpful in differentiating between the various causes of posterior thigh pain, which, in this case, facilitated detection of a sciatic nerve schwannoma and subsequent surgical removal. |
