A case of pulmonary foreign body granuloma formation after transcatheter arterial chemoembolization for hepatocellular carcinoma.

We experienced a case of pulmonary foreign body granuloma diagnosed by bronchoscopy in a patient with multiple lung lesions after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma. We speculate that the lesions may be caused by transarterial migration of the materials used for TACE.
