Findings: There is heterogenous appearance of the left testis parenchyma, enlargement of vessels, and disruption of the tunica albuginea.
Diagnosis: Fractured testis.

After truama, there are three clinical questions:

First -- is the tunica albuginea is in tact?  If so, then surgery is usually not required.  If disrupted, then surgery is required within 72 hours in order to preserve the testis.  In this case, given the findings and that the patient was outside of the 72-hour window, an orchectomy was performed (see images of gross specimen).

Second -- do abnormal findings represent a neoplasm? Trauma can also prompt a patient to palpate a previously undetected mass which may represent a tumor. 

Third -- is there torsion?  Trauma can induce testicular torsion.
