Metastatic melanoma Again seen are multiple enhancing masses within the subcutaneous tissues overlying the posterior calf. When compared to the prior exam, these have increased in size and has become somewhat confluent in nature and as a result, direct comparison/measurement is difficult. However, the medial-most lesion now measures 1.5 x 1.8 cm as compared to 1.2 x 1.2 cm, the middle lesion measures 2.8 x 3.4 cm as compared to 1.4 x 1.6 cm, and the lateral-most mass measures approximately 2 x 2.8 cm as compared to 2.2 x 1.3 cm. An area of skin thickening and enhancement slightly superior to these masses also appears larger. No new discrete foci of enhancement are identified. There is mild subcutaneous edema in the region of the masses.Marrow edema involving the medial tibial plateau appears improved from the prior exam and is likely degenerative in nature. The remaining marrow signal of the tibia and fibula is otherwise normal.
Interval increase in size of multiple enhancing masses within the subcutaneous tissues of the posterior calf consistent with progression of disease.
