Other potential diagnoses that may be demonstrated on US include testicular hematoma, rupture (particularly in patients with a history of trauma), infarct, torsion, intratesticular varicocele, and arteriovenous malformations or angiomatosis [35]. US Scrotum A variety of infectious and traumatic processes can be accurately depicted and characterized on grayscale US [36]. Sonographically, the involved testicle may have heterogenous, hypoechoic echotexture. Additional findings in testicular trauma may include contour abnormality, disruption of the tunica albuginea, or direct visualization of a fracture line. Sonographic appearance of intratesticular hematoma depends on the time from trauma, with the hyperacute or acute hematoma appearing as a heterogeneous or isoechoic area relative to surrounding testicular parenchyma, whereas chronic hematomas are smaller in size and relatively hypoechoic to anechoic. However, scrotal US without Doppler imaging may not be able to differentiate a hematoma from a mass or evaluate for inflammation. Variant 2: Newly diagnosed palpable scrotal abnormality. No history of trauma or infection. Initial imaging. CT Abdomen and Pelvis CT of the abdomen and pelvis is not routinely used as an initial imaging modality for the evaluation of newly diagnosed palpable scrotal abnormality in patients without history of trauma or infection. There is no relevant literature regarding the use of CT of the abdomen and pelvis in these patients. CT Pelvis CT of the pelvis is not routinely used as an initial imaging modality for the evaluation of newly diagnosed palpable scrotal abnormality in patients without a history of trauma or infection. There is no relevant literature regarding the use of CT of the pelvis in these patients. MRI Abdomen and Pelvis MRI of the abdomen and pelvis is not routinely used as an initial imaging modality for the evaluation of newly diagnosed palpable scrotal abnormality in patients without a history of trauma or infection.
