Summary
Magnetic resonance (MR) imaging effectively detects brachial plexus tumors in patients with and without neurological symptoms. This study highlights MR imaging
Area of Science:
- Radiology
- Oncology
- Neurology
Background:
- Brachial plexus tumors can present with or without neurological signs and symptoms.
- Accurate diagnosis is crucial for effective treatment planning.
Purpose of the Study:
- To evaluate the diagnostic utility of magnetic resonance (MR) imaging in identifying brachial plexus tumors.
- To assess MR imaging's accuracy in patients with and without suggestive clinical findings.
Main Methods:
- MR imaging was performed on 47 patients with suspected brachial plexus involvement.
- Both T1- and T2-weighted images were acquired in coronal, axial, or sagittal planes.
- MR findings were correlated with surgical confirmation or follow-up imaging.
Main Results:
- MR imaging correctly identified all 15 cases of tumor involving the brachial plexus in symptomatic patients.
- MR imaging accurately excluded brachial plexus tumor in 7 symptomatic patients.
- In asymptomatic patients, MR imaging correctly identified tumors adjacent to but not involving the brachial plexus.
Conclusions:
- MR imaging demonstrates significant clinical utility for evaluating suspected brachial plexus tumors.
- MR imaging is particularly valuable in patients presenting with suggestive neurological signs and symptoms.
- This modality aids in differentiating tumor involvement from adjacent masses.
