7-year-old female with history of left femoral osteosarcoma, concern for recurrence. Exam is significantly limited by metal related artifact from left femoral endoprosthesis.The prepubertal uterus appears normal. The ovaries are not visualized. The bladder is normal. There is no significant pelvic lymphadenopathy identified. No bowel abnormalities identified. The bone marrow signal appears normal in the pelvis and right femur. The left paraspinal muscles and left thigh musculature is diffusely atrophied.Evaluation of the hip joint itself is again limited by metal artifact. There is no evidence of gross disease recurrence or soft tissue mass identified. The known superolateral subluxation of the hip joint is better imaged on the current radiograph.
1.Extremely limited exam without gross evidence for disease recurrence.2.Diffuse muscle atrophy in the left hemipelvis and left lower extremity.
