Case 1: A 53-year-old male had undergone colectomy for descending colon cancer and subsequently received systemic chemotherapy for multiple liver metastases. The patient was found to have bilateral pulmonary nodules during follow-up. Spherical nodules were found in the right upper lobe and left upper lobe on CT, and they were suspected to be metastatic lung tumors. He underwent partial resection of the right upper lobe, and the nodule was revealed to be an intrapulmonary hematoma. He had a past history of chronic atrial fibrillation, and received the administration of Warfarin. Case 2: A 67-year-old male was referred to our hospital for the evaluation of an abnormal shadow on a regular check-up. He had a past history of valve replacement, and received the administration of Warfarin. A spherical mass was found in the left lower lobe on CT, and it was suspected to be a benign lung tumor or metastatic lung tumor. A CT-guided needle biopsy of the lesion showed intrapulmonary hematoma. Chest radiograph performed 4 months later showed obscuration of the mass. Intrapulmonary hematoma in patients lacking a history of chest trauma is very rare.
