[Pulmonary infiltrates, eosinophilia and polyneuritis]

A case of chronic eosinophilic pneumonia which, during the evolution, developed a very rare motor-sensitive polyneuritis of the lower limbs, is presented. We comment on the results of the electromyography, the neuromuscular biopsy and show the differential diagnosis with other diseases with lung infiltrates, peripheric eosinophilia and polyneuritis, such as hypereosinophilic syndrome, allergic angiitis and granulomatosis of Churg and Strauss.
