We present the case of a preschool child coming from the Yungas of La Paz which was admitted to the Hospital del Niño in La Paz with dysentery , malnutrition and a history of elimination of Ascaris through mouth, nose and rectum. The child received mebendazol against the enteroparasites, resulting in a clear improvement of the dysentery, while remaining hospitalized for treatment of other dysentery agents and nutritional rehabilitation. At seven days of his stay, the child suddenly presented breathing difficulty, clinical signs of a "sibilant lung" (crepitating, sibilant and roncus sounds in both lungs), marked peripheral eosinophilia of 24% ( eosinophil count 3,360 cells) and radiografíc images of the torax with diffuse bilateral interstitial infiltrations compatible with diffuse interstitial pneumonía . Since the child comes from a region with a high incidence of massive enteroparasitism, elimination of nematodes, simultaneous eosinophilia, sibilant lung, interstitial and temporal previously described, the disease is considered as Loeffler's Syndrome and treated accordingly with clinical improvement.
