Testicular vein thrombosis mimicking epididymo-orchitis after suspected Covid-19 infection.

A 70-year-old man presented to our vein clinic with intermittent and recurrent left testicular and groin pain, clinically resembling epididymo-orchitis. He had never had any genitourinary problems until contracting a severe flu-like illness in January 2020, strongly suspected to have been Covid-19. He had failed to respond on four separate occasions to antibiotics prescribed by his GP and had only responded on these occasions to aspirin. Duplex ultrasonography at our clinic showed thrombosis of the left testicular vein with venous collateral formation. The testicle itself showed mild oedema, but a reduced arterial flow supporting the pain to be secondary to thrombosis. Covid-19 is known to be associated with venous thromboembolic disease, but usually in patients sick enough to be hospitalised and particularly in those requiring intensive care. This man appears to have had a left testicular vein thrombosis secondary to relatively mild Covid-19 infection, as he did not require hospitalisation.
