title: Benign hemangioendothelioma--a rare type of posterior mediastinal mass in children.
abstract: Two infants with benign hemangioendotheliomas of the posterior mediastinum are reported here. The neoplasms did not produce symptoms and were fortuitously discovered by chest roentgenograms. Computed tomography (CT) was useful in delineating the extent of the lesions preoperatively.
