Abstract
Isolated mandibular metastasis is very rare from carcinoma urinary bladder with no locoregional lymph node involvement. Here, we present a case where staging fluorodeoxyglucose - positron emission tomography - computed tomography (FDG PET-CT) scan showed an FDG avid primary lesion in carcinoma urinary bladder with FDG avid erosion in the right mandibular condyle. However, since no pelvic lymph nodes were involved, the mandibular lesion was kept on follow-up and cystoprostatectomy was performed. Follow-up FDG PET-CT scan after 6 months revealed an osteolytic destructive lesion in the mandible with associated soft tissue component and the biopsy confirmed this as metastatic lesion.
