Wrist | Arthritis | Calcium pyrophosphate dihydrate deposition disease of the wrist. X-Ray, CT, MRI

78-year-old patient, left wrist pain with seizures and pain free intervals.


Figure A: MRI of the wrist, fat-sat DP coronal sequences and T1 coronal: scapho-trapezial arthropathies (red arrow) and interphalangeal proximal of the 4th finger (green arrow), congestive (bone edema, yellow arrow), and subchondral bone condesation (orange arrow).


Figure B: MRI T1 Fat-Sat sequence with injection of gadolinium chelates and CT scan performed without injection: scapho-trapezial synovitis (red arrow), sub-chondral bone condesation (blue arrow), calcifications of the scapholunate and lunotriquetral ligaments (orange and yellow arrows, respectively).


Figure C: Other patient: in addition to the signs already described, note the presence of chondrocalcinosis of the TFCC disk.

Figure D: Other patient: Pinching of the 2nd metacarpophalangeal (green arrow), and scapholunate diastasis (white arrow) testifying to a SCAC wrist stage II.
