[A case of limited Wegener granulomatosis with hypereosinophilia].
A 51-year-old female was admitted to Nagano Matsushiro General Hospital because of fever, cough and dyspnea on exertion. Her laboratory data revealed leukocytosis with hypereosinophilia, a high erythrocyte sedimentation rate and c-reactive protein. Chest radiography revealed an infiltration shadow with a cavity in the right upper lobe. A lung abscess was diagnosed and antibiotics were administered. Laboratory results showed improvement, but chest radiography continued to show cavities. She was admitted to our hospital because of fever, left pleural effusion and progression of cavities on chest radiographs. She showed no abnormalities of the upper airway or kidney, and was negative for c-antineutrophil cytoplasmic antibody (c-ANCA). Because a positive c-ANCA was seen on day 8 of hospitalization, L-type limited Wegener granulomatosis (WG) was diagnosed according to Gross et al. Prednisolone (PSL) was administered, which improved the anemia, eosinophilia and the cavities. On day 7 of PSL administration, of the left pneumothorax occurred as a complication caused by perforation of the left chest cavity, but her clinical course was good after a cavernectomy was performed. Some studies have reported that limited WG shows a negative c-ANCA, and that antibiotic therapy improves inflammation. The L-type of limited WG revealed a low-grade positive ratio and titer of c-ANCA. Moreover, L-type limited WG responds well to therapy. We therefore selected PSL administration only against L-type limited WG. We have reported L-type limited WG with eosinophilia and the negative effects of c-ANCA at an early clinical stage.
