Abstract:
A 61-year-old woman presented with chest pain. Chest CT revealed a mass of 6 cm diameter in the right lower lobe. Bronchoscopic biopsy showed squamous cell carcinoma. Video-assisted thoracotomy revealed that the main tumour was directly invading the liver through the diaphragm. To alleviate local symptoms and for possible cure with adjuvant chemotherapy and radiotherapy, standard right lower lobectomy and mediastinal dissection were carried out, followed by combined resection of the diaphragm and posterior superior segmentectomy of the liver. Eleven months postoperatively, the patient was alive but had a metastatic lesion in the other lobe of the liver which reduced in size following chemotherapy.
