What are the Ultrasound and MRI findings of segmental testicular infarction?
On US, segmental testicular infarcts appear as geographic rounded or wedge-shaped hypoechoic areas in the testicle with absent blood flow on Doppler US.
On MRI, they appear as geographic rounded or wedge-shaped areas with intermediate T1-weighted and low T2-weighted signal intensity relative to testicular parenchyma, sometimes with areas of high T1-weighted signal intensity when there is associated hemorrhage. These typically lack enhancement, although some peripheral enhancement may be present.
