Chronic Expanding Hematoma of the Thorax
ABSTRACT We report the first case in Korea of a chronic expanding hematoma, which presented as a huge mass in the pleural cavity. A 67-year-old woman exhibiting a slowly-expanding intrathoracic mass, as revealed by a chest radiograph, was admitted to our hospital. The patient had undergone a pneumonectomy 37 years earlier during treatment for pulmonary tuberculosis. Computed tomography revealed a huge mass in her right hemithorax. The differential diagnosis of this mass included chronic empyema combined with a malignancy, such as lymphoma or a soft tissue sarcoma. The tumor, which was classified as an encapsulated chronic hematoma, was removed surgically. Samples sent for histopathological and microbiological analysis revealed no evidence of neoplasia or infection. The patient was finally diagnosed with a chronic expanding hematoma of the thorax. This case is particularly rare due to the patient's development of a very large mass after undergoing treatment for tuberculosis more than 30 years earlier.

ABSTRACT: A 77-year-old man who had undergone mitral valve replacement 5 years previously presented with an intrapericardial mass. Computed tomography and magnetic resonance imaging showed that the mass lesion contained hematoma components. Positron-emission tomography (PET) with 2-[18 F] fluoro-2-deoxy-d-glucose (FDG) revealed uptake in the peripheral rim of the mass. These findings suggested the presence of hematoma associated with a malignant lesion. Surgical resection was performed, and the histological diagnosis was chronic expanding intrapericardial hematoma without neoplastic changes. Chronic expanding intrapericardial hematoma is a rare disease but should be considered when an expanding mass is found in a patient after cardiac surgery. The FDG-PET findings of chronic expanding hematomas, including FDG uptake in the peripheral rim of the mass as a result of inflammation, should be recognized as a potential interpretive pitfall that mimics a malignant tumor.Journal of Cardiothoracic Surgery 01/2013; 8(1):13.

ABSTRACT: Chronic expanding hematoma in the chest is identified as a specific type of chronic empyema. We encountered a case of chest chronic expanding hematoma presenting as a huge mass, which compressed the heart, trachea and esophagus. The disease was recognized as a cause of aspiration pneumonia and was successfully treated by surgical resection. Computed tomography revealed a large area of calcifications at the periphery of the mass. Magnetic resonance T2-weighted imaging indicated the mosaic patterns of various signal intensities as specific features of chronic expanding hematoma. Imaging diagnosis showed good correlation with pathology of the disease.Internal Medicine 02/2008; 47(15):1411-4. DOI:10.2169/internalmedicine.47.0724 · 0.97 Impact Factor

ABSTRACT: Chronic expanding heamatomas may present as masses mimicking chest wall tumors. We report the case of a patient who was presented with a giant posterior extrathoracic chest wall tumor. The mass was proven to be a chronic heamatoma possibly developed after a blunt thoracic injury which took place 2 years before presentation and was growing thereafter. Clinicians should have high suspicion of rare entities which mimic tumors and consider any information reported by the patient's history in their diagnostic process.Journal of Cardiothoracic Surgery 11/2011; 6:156.
