Multiple cell carcinoma, staging Within the posteromedial subcutaneous tissues of the lower extremity are multiple small enhancing foci reflective of the patient's known Merkel cell carcinoma. Index lesions are as follows (transaxial x craniocaudal dimensions as seen on post contrast axial sequence series 14):1. Image 25, 18 x 6 x 8 mm2. Image 12, 11 x 6 x 7 mm3. Image 11, 8 x 5 x 25 mmAdditional areas of slightly nodular enhancement are seen on image 8, 18 and 19. More proximally, there are no areas of abnormal subcutaneous enhancement. The signal intensity of the bone marrow and leg musculature is normal although there is mild diffuse fatty atrophy of the calf musculature. There is also mild nonspecific subcutaneous edema of the lower extremities beginning at the level of the mid diaphysis.
