21-year-old male with hip pain. Evaluate for AVN. Note is made of increased heterogeneous signal abnormality in the left femoral head consistent with avascular necrosis. There is no evidence of femoral head collapse or fracture. There is also increased serpiginous signal abnormality within the right femoral head consistent with avascular necrosis. No evidence of femoral head collapse or fracture. There is diffuse bone marrow signal abnormality consistent with the patient's history of sickle cell disease. There is residual fatty marrow in the greater trochanters. There is also increased signal abnormality within the sacrum, left inferior pubic ramus and posterior right acetabulum which may represent bone infarcts. There is deformity of multiple vertebral bodies of the incompletely imaged lower lumbar spine also consistent with the patient's history of sickle cell disease. Large amount of fluid is identified within the bladder. There is a small amount of fluid within the left hip joint which is not necessarily of any current clinical significance.
Findings compatible with avascular necrosis of the hips and other findings as described above.
