Small Cell Carcinoma of the Ureter With Early Recurrence and Multiple Metastases Shown on 18F-FDG PET/CT

Abstract

Abstract Primary small cell carcinoma of the ureter is an extremely rare malignancy with a poor prognosis. We present rare interesting 18F-FDG PET/CT images of primary small cell carcinoma of the ureter in a 37-year-old man with early recurrence and multiple metastases 2 months after laparoscopic left nephroureterectomy and pelvic tumor resection. PET/CT showed high FDG-avid lesions in the pelvis, peritoneum, the left posterior wall of the bladder, and in the right lung, providing important value in the detection of recurrence and systemic metastases.
