31-year-old female. Left-sided perineal pain. Found to have nonspecific lucencies of bilateral femoral neck and trochanters. Evaluate for cause of perineal pain and/or pelvic mass. Decreased T1 and T2 signal of the bone marrow symmetrically in the proximal femoral metaphysis and diaphysis as well as diffusely of the pelvis, most likely due to red marrow reconversion, which can be seen with anemic patients. No worrisome focal marrow signal abnormality is evident.Multiple small intramural T2 hypointense masses in the uterus consistent with fibroids. IUD is in place. No suspicious pelvic mass is identified.
1. Findings consistent with red marrow reconversion in the pelvis and proximal femurs, which can be seen with anemia. No focal worrisome marrow signal abnormality. 2. Small fibroids. No pelvic mass suspicious for malignancy.
