Female, 71 years old. Metastatic melanoma There are multiple foci of signal abnormality within the right sacral wing, both iliac wings, both ischia, and the left femoral head, compatible with metastatic disease. For reference, a lesion in the right sacrum measures 2.8 x 1.9 cm (series 601, image 35). The lesion in the left femoral head measures 1.6 x 1.2 cm (series 601, image 19). There are also additional lesions in the lower lumbar spine that are further described on the accompanying dedicated lumbar spine MRI report. There is relatively mild enhancement of these lesions following IV contrast administration. Please refer to the lumbar spine report for details regarding degenerative changes of the lumbar spine.There is mild generalized subcutaneous edema that appears to enhance mildly following contrast administration. This is nonspecific but compatible with mild inflammation. There is a fatty subcutaneous mass superficial to the lateral margin of the left gluteus maximus, likely representing a benign lipoma. Please note that the lateral extremes of the pelvis are not included within the field-of-view of this study.
Multiple metastatic osseous lesions throughout the pelvis with reference measurements as above.
