We successfully and safely performed a percutaneous transhepatic needle biopsy of an adrenal mass using ultrasonographic guidance in a patient with lung cancer. The patient was a 60-year-old woman with a non-functioning right adrenal mass which was detected incidentally during a systemic evaluation of lung cancer. To determine whether or not this adrenal mass was the result of metastasis, we performed a percutaneous transhepatic needle biopsy of the mass using ultrasonographic guidance. The histology of the mass revealed adrenal cortical nodular hyperplasia, which thus eliminated the possibility of metastasis from lung cancer. As a result the patient underwent a curable surgical resection of the lung cancer.
