history of soft tissue Ewing's sarcoma of the left hip status post resection. Large field-of-view images demonstrates interval decrease in size of a resection cavity in the subcutaneous fat of the upper left hip. Small field-of-view images demonstrate a T2 hyperintense, T1 hypointense resection cavity measuring approximately 3.9 x 3.5 x 2.3 cm TR x AP x CC (series 6, image 18 and series 8, image 22), previously 3.9 x 5.8 x 3.3 cm. There is no involvement of the underlying gluteus muscles. Susceptibility artifact from metal is noted within the resection cavity. There is minimal enhancement without nodular enhancement on postcontrast images.The visualized intrapelvic structures are within normal limits. No osseous abnormality is noted.
Interval decrease in size of resection cavity in the upper left hip without nodular enhancement to suggest residual or recurrent disease.
