Forearm MRI Cases

<div>HISTORY:&#160;This 61-year-old male presents with mass at right wrist and forearm.(QUIZ ANSWER) MASS COULD POTENTIALLY BE:&#160;All of the above.Using the&#160;diagnostic web viewer, we have provided images that assist in telling our clinical story. Areas of significance are indicated below.FINDINGS: No acute bony macrofracture or contusion. Negative ulnar variance within normal limits. Triangular fibrocartilage intact. Carpal bone is normal in alignment. Mild lateral subluxation of the 1st metacarpal. Mild spurring at the 1st carpometacarpal joint.&#160;Extensor tendons intact.&#160;A 4.7 x 3.5 x 8.5cm mass at the volar aspect of the distal forearm between the flexor digitorum superficialis and flexor digitorum profundus and splaying of medial nerve. Areas of hyperintensity on T1 sequence in the lesion with blood or fat. An area of irregular hypointensity similar to that of the muscles on both T1 and T2 sequences.&#160;CONCLUSION:&#160;Heterogeneous aggressive-appearing mass at the forearm suspicious for sarcomatous lesions such as liposarcoma, malignant fibrohistiocytoma, epithelioid sarcoma, and synovial sarcoma. Recommend MRI with contrast for further evaluation.</div>
