Imaging findings
A 35-year-old man with abdominal pain and a scrotal mass presented with a chest x-ray showing multiple bilateral pulmonary nodules. CT confirmed the nodules, which exhibited characteristic surrounding ground-glass halos consistent with hemorrhage. Supraclavicular lymphadenopathy was also present.
Key takeaways
Pulmonary nodules with surrounding ground-glass halos ("halo sign") are highly suggestive of hemorrhage, and when seen in the setting of metastatic disease, particularly from a testicular mass, should raise suspicion for choriocarcinoma. Other differential considerations for hemorrhagic metastases include melanoma, thyroid, renal cell carcinoma, and angiosarcoma.
