Imaging findings in a 50 year old woman with known history of melanoma. (a) CT image showing an oval mass with homogeneous contrast enhancement (type I) in the left gluteal musculature. (b) The lesion is hypointense on T1w image (spin echo pulse sequence, TR/TE: 569/11 ms). (c) The lesion is hyperintense on T2w image (short tau inversion recovery (STIR), TR/TE: 5210/80 ms). (d) After intravenous administration of contrast medium the lesion shows marked homogeneous enhancement (T1w spin echo with fat saturation, TR/TE: 610/12 ms).
