| Popis: | We report an unusual case of a 59-year-old man with recurrent right ear melanoma resulting in perineural spread to the right greater auricular nerve. Direct perineural spread to the greater auricular nerve is not commonly reported in melanoma. Our case demonstrates perineural spread along the greater auricular nerve on 18F-FDG PET/CT and MRI. This finding was supported by intraneural invasion noted at the surgical margin of the wide local excision of the right helix melanoma. Resolution of FDG activity and improved MRI appearances of the right greater auricular nerve were seen after immunotherapy treatment. |
