Forma pulmonar crônica da esquistossomose mansoni: avaliação clínico-radiológicaAbstract
One hundred and fifteen patients with Schistosomiasis mansoni were studied: 31 with a normal chest x-rays and no signs of pulmonary hypertension (PH) and 84 with x-rays compatible with cardiopulmonary abnormalities (73 without symptoms and 10 with symptoms of PH). The chronic pulmonary form (CPF) without pulmonary hypertension is frequent and benign. There was no association between the CPF and the hepatosplenic form (HEF),nor with age, sex or patient origin. Pulmonary hilum alterations were the most common x-ray findings, followed by parenchymatous abnormalities (micronodules). The CPF was associated with a low to medium worm burden. The incidence of CPF with pulmonary hypertension is low but usually related to significant heart abnormalities. It is more common in patients over 12 years, with the HEF of the disease and has no correlation with sex, race or place of birth. Chest x-ray alterations are seen with similar frequency both in parenchymatous and hilar regions.
