Summary
This review covers common benign hand and wrist masses, focusing on their distinct radiographic and MRI appearances. Understanding these imaging features aids in diagnosing conditions like ganglion cysts and giant cell tumors.
Area of Science:
- Radiology
- Orthopedic Imaging
- Musculoskeletal Imaging
Background:
- Wrist masses present a complex diagnostic challenge.
- Most hand and wrist masses are benign with characteristic imaging findings.
Purpose of the Study:
- To review the imaging characteristics of common hand and wrist masses.
- To highlight the magnetic resonance (MR) appearance of these lesions.
Main Methods:
- Review of imaging characteristics of common hand and wrist lesions.
- Emphasis on magnetic resonance (MR) imaging findings.
Main Results:
- Ganglion cysts, giant cell tumors of the tendon sheath, and hemangiomas are the three most common lesions.
- Other common diagnoses include lipomas, neural sheath tumors, infection, inflammation, and variant soft-tissue or bony structures.
- Fibrolipomatous hamartoma, though rare, has a distinctive radiographic appearance.
Conclusions:
- Radiographic and MR imaging are crucial for diagnosing benign hand and wrist masses.
- Familiarity with characteristic imaging features facilitates accurate diagnosis and management.
