Although a plain radiograph will provide visualization of the cyst, it can identify bony abnormalities that may be causing the symptoms or may contraindicate treatment. In older adults, degenerative joint disease may accompany the cyst at the scaphotrapeziotrapezoid joint and can be confirmed by the plain radiograph. Magnetic resonance imaging, ultrasonography, or arthroscopic imaging may prove useful in obtaining confirmation of clinical diagnostic findings.[2, 5, 12]
An Allen test should be performed when cysts are located near the radial artery, including most volar wrist ganglia. Ultrasonography is an inexpensive and noninvasive method of assessing the soft tissue.
