ABSTRACT

Introduction: Vena cava thrombus is an extremely rare complication of testicular tumors.

We report on an unusual case of testicular tumor presenting with inferior vena cava thrombus extending from the left spermatic and bilateral external iliac veins to the hepatic vein.

Case report: A-35-year old man presented with a 6-month history of left scrotal mass and a 1-day history of bilateral lower extremity edema. Computed tomography (CT) revealed the presence of thrombus extending from the left spermatic vein and bilateral external iliac veins to the hepatic vein, and multiple lymph node and lung metastases.

3 cycles of chemotherapy were given after the left high inguinal orchiectomy. Pathological examination demonstrated a pure yolk sac carcinoma with lymphovascular invasion and direct tumor extension into the left spermatic cord. CT and positron emission tompgraphy-CT obtained no findings of metastasis or recurrence at 3 months after the chemotherapy.

Conclusion: We review this seldom case and discuss the literature with regard to its diagnosis and treatment.
