Acute segmental testicular infarction: differentiation from tumour using high frequency colour Doppler ultrasound.

Segmental testicular infarction is rare, of variable aetiology but usually idiopathic. B-mode ultrasound may demonstrate a focal mass indistinguishable from a testicular tumour, with confirmation only achieved following surgery. We report a case of segmental testicular infarction presenting as a heterogeneous mass on B-mode ultrasound, confidently diagnosed as an area of infarction on high frequency colour Doppler ultrasound and proven on histology. The pre-operative differentiation of tumour from segmental infarction allows testis-sparing surgery.
