[Intrapulmonary hematoma masquerading as metastatic carcinoma of lung cancer].

ABSTRACT

We herein report a case of intrapulmonary hematoma after lobectomy for lung cancer. A 51-year-old male underwent right upper lobectomy for lung cancer in a thoracoscopic procedure. Three months after the operation, chest computed tomography showed a 16-mm well-circumscribed nodule in the right lower lobe suggesting metastatic carcinoma for lung cancer. We performed the partial resection of the right lower lobe. The histological examination confirmed the diagnosis of an intrapulmonary hematoma. When pulmonary shadow appears after lung operations, intrapulmonary hematoma is one of a choice of differential diagnosis. Magnetic resonance imaging may be useful in establishing the diagnosis when intrapulmonary hematoma is suspicious clinically.
