Hot Gloved Finger Sign in Endobronchial Metastasis From Hepatocellular Carcinoma on FDG PET/CT.

ABSTRACT
Endobronchial metastasis from hepatocellular carcinoma is exceedingly rare. We describe FDG PET/CT findings in a case with isolated endobronchial metastasis from hepatocellular carcinoma 13 years after hepatectomy. The endobronchial metastasis appeared as hypermetabolic branching tubular opacities, producing a hot gloved finger sign on FDG PET/CT. This case indicates that the hot gloved finger sign may be suggestive of extensive endobronchial growing of a malignant condition but not endobronchial mucoid plug.
