Organizing hematoma of the paranasal sinuses is a diagnostic dilemma clinically and radiographically, mimicking benign or malignant neoplastic processes. Although the diagnostic rate of this disease has increased as characteristic imaging findings are somewhat elucidated, endoscopic examination, preoperative biopsy, and computed tomography (CT) imaging do not give helpful information in differe...

A 57-year-old male patient was admitted to our center because of a cystic mass on the lower portion of the right major fissure that was found incidentally by chest X-ray. He did not have a history of trauma or anticoagulant use. The lesion was removed by video-assisted thoracoscopic surgery. Pathological examination revealed an organizing pulmonary hematoma without any complications, and a foll...

PURPOSE We aimed to evaluate the histologic and radiologic findings of vascular lesions after stereotactic radiosurgery (SRS) categorized as radiation-induced cavernous hemangioma (RICH). MATERIALS AND METHODS Among 89 patients who underwent neurosurgery for cavernous hemangioma, eight RICHs from 7 patients and 10 de novo CHs from 10 patients were selected for histopathological and radiologic...

Chronic expanding organizing hematoma (CEH), also known as chronic expanding hematoma, is a benign condition in which a hematoma does not undergo resorption, but rather it persists or even expands slowly. The term was first coined by Reid et al. (1), and the authors defined CEHs as hematomas that increase in size for over 1 month after the causative event. The clinical importance of this lesion...

A pseudoaneurysm occurs when incomplete rupture of the heart seals within organizing thrombus, hematoma, and pericardium and maintains communication with the left ventricle. A pseudoaneurysm may cause arterial emboli and drain off a considerable portion of ventricular stroke volume. Cardiovascular magnetic resonance imaging proves to be an adequate technique to not only identify pseudoaneurysms...
