title: Low-attenuation thoracic metastases in testicular malignancy.
abstract: Low-density abdominal and pelvic lymph nodes are seen in nearly half of patients with testicular cancers. Thoracic low-attenuation metastases are much less common. Three cases of low-density metastases to lung parenchyma and mediastinal nodes are presented. In a man of appropriate age, a low-attenuation pulmonary or mediastinal mass should prompt a search for a primary testicular neoplasm.
