[Usefulness of Doppler-color ultrasonography and identification of resistance indexes as early indicators of testicular infarction secondary to orchiepididymitis]. / Utilidad de la ecografía Doppler-color y la determinación de los índices de resistencia como indicadores precoces de infarto testicular secundario a orquiepididimitis.

The testicular infarction can be a rare complication of the orchiepididymitis. The ultrasonography appearance of the partial infarctions creates confusion with expansive intratesticular processes. We present three cases of focal testicular infarction associated with orchiepididymitis, stressing the usefulness of the Color doppler sonography for detecting the avascular nature o these lesions. The determination of de indeces of resistance (IR) in the doppler spectrum of intratesticular arteries showed a highly increased vascular resistance in respect of the healthy testicle. In patients with grave orchiepididymitis vein drainage can be affected due to compressive edema or to thrombosis, causing the raising of the resistance indeces. Acknowledging the avascular resistance of the focal post-orchiepididymitis infarction we can prevent unnecessary orchiectomy.

[Costal osteolysis due to a giant arteriosclerotic aneurysm of the ascending thoracic aorta]. / Osteólisis costal por un aneurisma arteriosclerótico gigante de la aorta torácica ascendente.

In this case report the patient had a giant saccular aneurysm caused by arteriosclerosis, located in the ascending aorta and protruding through the anterior thoracic wall, with osteolysis of the two adjacent ribs. Costal involvement in arteriosclerotic aneurysms has not been described in the literature. We review the incidence, types and clinical signs of aneurysms of the ascending aorta, emphasizing the complications caused by arteriosclerotic aneurysms.
