Lung cancer is currently one of the most common malignancies in the world. Metastatic disease is observed in ~ 40% of patients with lung cancer, with the most common sites of metastasis being the bone, liver, brain and adrenal glands. Peritoneal carcinomatosis (PC) is defined as the progression of the primary cancer to the peritoneum. PC is a rare clinical event in lung cancer. Tyrosine kinase inhibitors targeting the epidermal growth factor receptor (EGFR), such as erlotinib are used for the treatment of patients with advanced non-small cell lung cancer (NSCLC). F-18 FDG PET/CT has proven capable of predicting response to therapy with erlotinib. We present a rare F-18 FDG PET/CT image findings of a 45 year old male with NSCLC with PC treated with erlotinib showing response to the treatment.
