November 2023 | Case of the Month for Residency Program

A 77-year-old male with a history of COPD, AAA, and a 55-pack year smoking history was found to have a left lung lower lobe spiculated nodule on a routine low dose chest CT. He was referred for a CT guided biopsy (pictured below) which showed malignant cells. However, due to scant cellularity, IHC was unable to be performed. A PET scan was ordered and showed a hypermetabolic liver lesion measuring 3 cm. No other masses were present. The patient has no prior history of malignancy. The liver mass was biopsied and is shown below.
