CEUS appearances of extra-testicular haematoma. On B-mode (a), a note is made of an extratesticular hypoechoic haematoma (asterisks) causing compression of the testicular parenchyma. Essential issues in such cases include the thorough assessment of testicular parenchymal perfusion and integrity of the adjacent tunica, to rule our testicular rupture. CEUS (b) showed uniform enhancement of the testis and excludes focal ischaemia secondary to extrinsic compression, confirming that the tunica albuginea is intact. The extratesticular haematomas shows no internal enhancement (asterisks) but a rim of perilesional hyperaemia
