my impression from my mri of my left hand states minimal muscle edema thenar eminence and second metacarpal flexor digitorum musculature the area of minimal muscle edema does correspond to the reported palpable abnormality. the is minimal spurring at the first and fifth metacarpophalangeal joints with prominence of the distal firth metacarpal possibly related to spurring versus osteochondroma or exostosis. no evidence for acute ossesous , tendinous or ligamentous abnormality and no focal mass is seen
Hi you appear to have a swelling on the palm of your hand. This is from edema or swelling of the small muscles of the hand possibly from injury. The MRI also shows some arthritic changes at the joints between the thumb and little finger and the bones of the palm called metacarpals. In addition, the bone in the palm connecting the little finger has a small bony outgrowth which could either be due to arthritic bony extension or a harmless bony outgrowth called osteocyte Chat Doctor.  All these are not very significant except for the muscular swelling which by itself is not serious.
