Abstract:
:We report a case of pulmonary venoocclusive disease in which chest radiography, when supplemented with computed tomography after contrast medium administration, was specific enough to make the diagnosis without resorting to more invasive, potentially dangerous procedures. A brief review of the literature, with emphasis on etiology, pathogenesis, and possible therapeutic approaches, emphasizes the importance of early diagnosis of this rare and usually fatal disease.
