Corpora cavernosal haematoma. A 34-year-old male presented after a high-energy traffic accident with swelling and deformity of the penis. a On the B-mode US in an axial plane at the base of the penis, there is an enlargement of the left corpus cavernosum due to an area of mixed reflectivity (arrowhead). Following UCA injection (b) the dual aspect view (low MI B-mode image on the right) demonstrates no enhancement of the area on the CEUS image (arrowhead). These findings are in keeping with a cavernosal haematoma. There is no active contrast extravasation nor tears of the tunica albuginea. Note that CEUS allows a clear delineation of the borders of the haematoma, which may be obscured on B-mode imaging alone
