This is a 66-years old lady operated for thymoma. A routine follow-up PET/CT showed an active right pleural/extrapleural nodule in the lower hemithorax with another smaller nodule in the subcutaneous fat. She had non-active right pleural thickening and another subpulmonic non-active nodule (arrowhead on the PET image). This may have been due to seeding along an ICD track, but I couldn’t find comparative images with an ICD.
The biopsy using an 18G coaxial gun was straightforward and showed recurrent squamous carcinoma of thymus.
