Reason: Re evaluate for osteomyelitis History: disseminated mycobacterial infection Direct comparison with prior study is limited due to limited field-of-view on prior study and patient refused additional images at the time. Redemonstration of distal ulnar bone marrow signal changes representing osteomyelitis measuring approximately 4.5 cm in length. This lesion appears more prominent compared to prior study indicating progression. There is also surrounding soft tissue inflammatory changes with small fluid collection in the radial aspect of the distal ulnar diaphysis measuring 6 mm x 3 mm with mild rim enhancement.
1.Previously seen ulnar osteomyelitis is more prominent on current study indicative of progression.2.Small phlegmon adjacent to the distal ulna as above.
