Reason: 15-year-old female with history of alveolar rhabdomyosarcoma, evaluate. PELVIS:UTERUS, ADNEXA: Stable mild T2 hyperintensity and enhancement of the labia.BLADDER: No significant abnormality noted.LYMPH NODES: Reference right inguinal lymph node measures 11 x 7 mm on image 9 of series 601 and is unchanged. BOWEL, MESENTERY: The imaged bowel appears normal.BONES, SOFT TISSUES: Previously noted area of increased STIR/T2 bone marrow signal abnormality in the right femoral head and neck is no longer visualized.Stable size and enhancement at the resection bed in the pelvis, including the right obturator internus muscle.OTHER: Diminished caliber of the right iliac and right femoral vein persists. Small amount of free pelvic fluid, likely physiologic in a patient of this age.
1. Interval resolution of the bone marrow edema of the right femoral head and neck.2. Post surgical changes in the pelvis with no evidence of disease recurrence.
