Neumonía eosinófila crónica en la provincia de Soria (1995-2004). Revisión de la bibliografía

NEC is a rare disease that requires the finding of either peripheral or pulmonary eosinophilia for its diagnosis. A typical symptom with alveolar infiltrates observed on a chest X-ray and peripheral eosinophilia suggests a NEC diagnosis, although this must be confi rmed by the bronchoalveolar lavage (LBA) a lung biopsy may be necessary. Treatment must be maintained for at least 6 months. Relapses are frequent.
