INTRODUCTION: Metastatic disease to lung can present with a variety of appearances. We present a case of colonic metastasis to the lung that presented as diffuse infiltrates.
CASE PRESENTATION: A 55 year old male presented to the E.R. complaining of shortness of breath and cough productive of yellow sputum with intermittent fever for 3 months. He was recently treated in another hospital for pneumonia. On presentation, he had fever of 102°F, tachycardia, tachypnea and severe hypoxia requiring a high FiO2. Chest X-ray showed bilateral diffuse fluffy infiltrates. CT chest showed bilateral airspace densities with areas of confluent consolidation, interlobular septal thickening, hilar lymphadenopathy and bilateral pleural effusions, consistent with atypical pneumonia. He was admitted to the ICU for acute respiratory failure due to suspected HCAP and treated with antibiotics. Further investigation revealed a recent diagnosis of poorly differentiated adenocarcinoma of the sigmoid colon. A VATS with pulmonary wedge biopsy revealed metastatic adenocarcinoma of gastrointestinal phenotype with positive KRAS mutation. He was started on FOLFOX based chemotherapy. CT scan 4 months later showed marked improvement of the airspace disease and resolution of mediastinal lymphadenopathy.
