Hand lipomas: detection and characterization by magnetic resonance imaging
1Department of Radiology, University of California, Davis School of Medicine, Sacramento 95817.
Summary
Magnetic resonance imaging (MRI) identified hand masses as lipomas. These benign tumors presented characteristic imaging features, aiding diagnosis when clinical examination was inconclusive.
Area of Science:
- Orthopedic Surgery
- Radiology
- Dermatology
Background:
- Hand masses can present diagnostic challenges.
- Accurate diagnosis is crucial for appropriate treatment planning.
Observation:
- Two patients presented with palmar hand masses.
- Initial clinical examination did not reveal the etiology of the lesions.
Findings:
- Magnetic resonance imaging (MRI) revealed the masses to be lipomas.
- MRI demonstrated characteristic features: smooth, lobulated margins, low signal intensity septations, high T1 signal, and intermediate T2 signal.
Implications:
- MRI is a valuable tool for diagnosing hand lipomas.
- Understanding imaging characteristics aids in differentiating lipomas from other hand masses.
