Decubitus ulcers Note that the exam is limited by the presence of only the axial T1 and axial T2 fat sat sequences.BONE MARROW: The marrow demonstrates a diffusely heterogeneous appearance however there is no discrete low T1 signal to confirm osteomyelitis. Sclerotic changes noted within the femoral head bilaterally likely relate to avascular necrosis. The right femoral head is superiorly migrated but remains within the acetabulum.SOFT TISSUES: There is diffuse fatty atrophy of the pelvic musculature. There is mild decubitus ulceration of the subcutaneous tissues of the right buttock. Underlying this area is a heterogeneous collection containing low peripheral signal with central areas of fluid signal intensity. A similar appearing collection is seen within the left gluteal tissues again demonstrating a low peripheral signal with areas of fluid signal centrally. These findings are thought to represent hematomas although the possibility of superimposed infection cannot be excluded. Note that the collection along the left gluteal musculature does not demonstrate a fistulous tract with the skin surface.
1. No definite evidence of osteomyelitis. The marrow signal is heterogeneous in nature with probable avascular necrosis of the femoral heads although correlation with recent CT is recommended.2. Ill-defined collections within the gluteal musculature bilaterally are thought to represent hematoma, likely chronic, although the presence of superimposed infection cannot be excluded.3. Additional chronic findings described above.
