55-year-old man with an unknown primary melanoma who had been treated with ICIs for 35 months (Pembrolizumab). 3D MIP view shows multiple intermuscular foci in the lower limbs (B, lower panel). Also noteworthy is a benign uptake in the right groin (B, black arrow) related to a right inguinal mesh repair (white arrow), not to be confounded with a recurrence in the area of the lymphadenectomy (white dotted arrow)
