Reason: left volar ulnar wrist mass r/o ganglion cyst History: mass and pain Multiple sequences are slightly limited by patient motion. We see no well-defined soft tissue mass such as a ganglion. There is mild reticulation of the subcutaneous fat volar to the pisiform and ulnar neurovascular bundle. This is nonspecific and could reflect small focus of inflammation or perhaps a small collection of blood vessels (e.g., small vascular malformation), but this is equivocal. Please note that it can be difficult to identify subcutaneous lipoma amidst normal subcutaneous fat. Otherwise we see no soft tissue mass.The ulnar nerve appears slightly prominent before entering Guyon's canal, but this is not necessarily of clinical significance. Median nerve is unremarkable.Flexor and extended tendons are within normal limits. Bone marrow signal and osseous alignment are within normal limits.There is small amount of fluid and enhancement in the distal radioulnar joint, conceivably reflecting mild synovitis, but of questionable significance.There is thinning and perhaps focal perforation of the articular disc of the triangular fibrocartilage complex just medial to the radial attachment, but this is not necessarily of current clinical significance.Small ossicle adjacent to the ulnar styloid may reflect prior trauma, of doubtful current clinical significance.Please note that this study is not optimized to evaluate for ligaments, but we see no gross abnormality.
No discrete mass is identified on this study. Mild reticulation of the subcutaneous fat volar to the pisiform and ulnar neurovascular bundle is nonspecific and may reflect focal inflammation or perhaps a small vascular malformation, but this is equivocal. Please note that it can be difficult to identify subcutaneous lipoma amidst of normal subcutaneous fat.
