Patient with recurrent vulval carcinoma. On the axial T2-weighted MRI (a), there is a large lymphocyst in the left groin due to previous groin node dissection (small arrow). The recurrent tumour is seen in the vulva (large arrow). The patient underwent percutaneous drainage of the lymphocyst. Following this, FDG-PET/CT was undertaken to exclude other sites of disease prior to planning further surgery. Fused FDG-PET/CT confirmed multifocal disease in the vulva (small arrows). Low-grade FDG uptake is seen in the wall of the drained lymphocyst, consistent with probable inflammatory change. No FDG-avid disease was seen elsewhere.
