title: Intralobar sequestration presenting as a large intrapulmonary hematoma and massive hemothorax.
abstract: Intralobar sequestration is a relatively rare anomaly that is usually diagnosed with symptoms of cough, expectoration, or recurrent pneumonia. We experienced a case of a 27-year-old man with a symptom of massive hemoptysis. His chest computed tomography (CT) scan revealed a large intrapulmonary hematoma and massive hemothorax, mimicking a benign lung tumor ruptured into the pleural cavity. We should keep the possibility of this anomaly in mind if a patient with hemoptysis has a cystic lung tumor and hemothorax on CT scan.
