26-year-old female with AML in remission There is mild edema and enhancement along the myotendinous fibers of the iliopsoas and distal piriformis that is nonspecific, but may represent mild strain or inflammation. No fluid collection is evident. No joint effusion or evidence of synovitis. The remaining musculature is within normal limits. Again seen is increased marrow signal abnormality within the subtrochanteric femur that is predominantly isointense to muscle on T1-weighted sequences and hyperintense to muscle on T2 weighted sequences, which is nonspecific and could reflect the patient's known leukemia or sequelae of its treatment. The region of signal abnormality is slightly smaller on the current study compared with the prior dated 11/15/14. There is also a subcentimeter focus of signal abnormality within the supraacetabular right ilium that was likewise present on the prior study.
1. Edema and enhancement of the distal iliopsoas and piriformis myotendinous fibers that is nonspecific, but could represent strain or inflammation. We see no fluid collection or abscess.2. Marrow signal abnormality as described above, appearing similar or slightly less extensive than on the prior study.
