[Clinico-radiologic and morphopathologic aspects of mediastinal-pulmonary hemangiopericytoma].

The paper points out the diagnosis of intrathoracic hemangiopericytoma in 13 patients in the "M.Nasta" Institute of Pneumophthisiology, a seldom seen disease considered quite serious because of its malignant form and its late finding out. This is due to its non-distinctive, small number of symptoms, which has a negative influence upon the disease prognosis and evolution.
