A 63-year-old man presented with a 2 month history of intermittent right subcostal and shoulder tip pain. Preoperative imaging confirmed a locally advanced right lower lobe lung tumour involving the diaphragm and liver. Bronchoscopic biopsy confirmed squamous cell carcinoma and mediastinoscopy was negative. The patient underwent a right bilobectomy with resection of the right hemi-diaphragm and a right hemi-hepatectomy. His postoperative recovery was satisfactory and he remains well 18 months after the surgery. We believe that in selected cases, patients with locally advanced lung tumours invading the liver may have a survival advantage following resection.
