Transitional Cell Carcinoma With Metastases to Spermatic Vein and Spermatic Cord: PET/CT Imaging

Renal cell carcinoma metastases to the spermatic cord: review of the literature and case presentation

We present a case of clear cell renal cell carcinoma with metachronous metastasis to the ipsilateral spermatic cord. We also review the literature of the rare instance of renal cell carcinoma metastasising to the spermatic cord.

Spectrum of malignant renal and urinary bladder tumors on 18F-FDG PET/CT: a pictorial essay

A wide variety of malignant renal and urinary bladder diseases can be detected on (18)F-FDG PET/CT. Although the PET/CT findings are often nonspecific, the aim of this atlas was to demonstrate that the spectrum of renal and urinary bladder malignancy that can be evaluated with PET/CT is much broader than current medical literature would suggest. PET/CT readers and oncologists should be aware of the variety of urological tumor types that can be detected on PET/CT and some of the patterns of (18)F-FDG uptake that can be observed in these cases.

Primary testicular lymphoma involving the spermatic cord and gonadal vein

We report a case of a 70-year-old man with a history of prostatic adenocarcinoma and a 3-month history of right hemiscrotal swelling. The patient underwent a CT scan, scrotal ultrasound, and F-18 FDG-PET scan to evaluate for metastatic prostate cancer. The CT scan demonstrated an ill-defined soft-tissue mass extending along the right gonadal vein. Scrotal ultrasound revealed a heterogeneous right testicular mass. The F-18 FDG-PET scan demonstrated intense hypermetabolic activity along the course of the right gonadal vein extending to the right hemiscrotum. Subsequent right radical orchiectomy and pathologic examination revealed a B-cell lymphoma, infiltrating the testicular parenchyma, spermatic cord, gonadal vessels, and adjacent soft-tissues. Lymphoma or other tumors rarely infiltrate the spermatic cord, and have only very rarely been demonstrated on PET imaging.
