How to Diagnose a Ganglion Cyst: A Simple Guide
Published: Oct 27, 2023
Accurate diagnosis of ganglion cysts can prevent unnecessary worry and guide appropriate treatment. Learn the simple steps to identify these common swellings.
Physical Examination Insights
The physical exam is the first step in diagnosing ganglion cysts. Look for a firm, smooth, and rubbery swelling that might change size. Transillumination, where light passes through the cyst, helps confirm it's fluid-filled.
Imaging Techniques
Ultrasonography and MRI are valuable tools in diagnosing ganglion cysts. Ultrasound shows well-defined margins and acoustic enhancement, while MRI highlights smooth, homogenous cystic masses distinct from other abnormalities.
When to Consider Biopsy
If the cyst grows rapidly, causes pain at rest, or is atypically located, a surgical biopsy may be necessary. These signs could indicate a more serious condition requiring further examination.
