Pulmonary sequestration and aspergillosis

Abstract

Pulmonary sequestration (PS) is an uncommon congenital disease. Symptoms when present are usually secondary to pyogenic infection. Our objective was to draw attention on superimposed fungal infection. During the last 20 years, we operated upon 19 intralobar PS. Four of six patients operated during the last decade proved to have intralobar PS containing Aspergillus. In one patient aspergillosis presented as an aspergilloma and communications between the sequestration and small bronchi were present. In another patient diagnosis was made before operation because of positive precipitins test. In two patients aspegillosis was discovered by the pathologist. Review of literature demonstrates PS fungal colonization to be a rare but recently reported entity (14 cases reported). The observation of four consecutive patients leads us to suggest that PS aspergillosis must be considered in order to evaluate its incidence.
