CT of pulmonary epithelioid hemangioendothelioma
To describe the radiological findings of long-standing pulmonary epithelioid hemangioendothelioma. Serial radiography and CT, including high-resolution CT scans, were performed in two patients. The tumor has remained radiographically stationary for 10 and 20 years, respectively. On CT, both patients showed multiple calcified pulmonary nodules, up to 1 cm in size with a perivascular distribution. Interstitial involvement was seen in one case. Calcification and perivascular location of the tumoral nodules were characteristic CT findings in our cases.
