Summary
This study details 20 arm schwannomas in 13 patients, noting clinical signs like Tinel
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Radiology
Background:
- Schwannomas are nerve sheath tumors that can occur in the extremities.
- Arm schwannomas can present with various clinical symptoms and require accurate diagnosis.
Purpose of the Study:
- To describe the clinical characteristics, MRI findings, and surgical outcomes of schwannomas located in the arm.
- To evaluate the diagnostic accuracy of MRI for arm schwannomas.
Main Methods:
- Retrospective review of 20 arm schwannoma cases in 13 patients.
- Analysis of clinical presentation, neurological signs (e.g., Tinel's sign), and muscle function.
- Review of preoperative magnetic resonance imaging (MRI) findings.
- Description of microsurgical excision techniques and postoperative follow-up.
Main Results:
- Twenty schwannomas were surgically treated in 13 patients.
- Positive Tinel's sign was observed in 12 cases.
- MRI correctly diagnosed schwannoma in 6 out of 9 examined cases.
- Microsurgical excision resulted in two transient postoperative neurological complications.
Conclusions:
- Arm schwannomas exhibit distinct clinical and radiological features.
- MRI has a moderate diagnostic accuracy for arm schwannomas.
- Microsurgery is an effective treatment for arm schwannomas with a low rate of transient complications.
