ABSTRACT

One patient, a 72-year-old man, was admitted to the hospital complaining of prolonged cough for three months. Chest CT showed bilateral peripheral consolidations with CT angiogram signs. The diagnosis of invasive mucinous adenocarcinoma was made by autopsy. The other patient was a 68-year-old woman with bilateral consolidations refractory to the treatment with antibiotics and corticosteroids. Chest CT showed bilateral peripheral consolidations with CT angiogram sign. She was diagnosed with invasive mucinous adenocarcinoma by transbronchial lung biopsy. CT angiogram sign is a characteristic sign to invasive mucinous adenocarcinoma and is useful for this diagnosis.
