History of soft tissue sarcoma of the left thigh, rule-out recurrence. Again seen is a surgical scar through the posterior subcutaneous fat of the thigh. An elongated collection of fluid signal intensity in the posterior aspect of the thigh is slightly smaller on the current study than on the prior study now measuring approximately 1.5 cm in diameter with thin peripheral enhancement, likely representing a seroma. Additional post-operative changes appear similar to the prior study. There is edema and mild enhancement of the adductor muscle which is slightly less pronounced on the current study than on the prior study. We see no findings to suggest tumor recurrence. We see no lesions in the bone marrow. Metal susceptibility artifact of a right hip arthroplasty device.
Post-operative changes as described above. We see no evidence of recurrence.
