Abstract
- Hypereosinophilic syndrome is a rare entity of eosinophilic lung disease characterized by idiopathic prolongedeosinophilia of marked degree and variable organ involvement. Pulmonary involvement of hypereosinophilic syndromeoccurs in up to 40% of patients. We report HRCT findings of three patients with pulmonary involement of hypereosinophilic syndrome diagnosed by clinical manifestation, bronchoalveolar lavage and transbronchial lungbiopsy. On HRCT, several small nodules were seen in both lungs, especially in peripheral lung areas of the three patients. One had nodules with ground-glass attenuation halo and also focal areas of ground-glass attenuation inthis area.
