  • Abstract
  • Look Inside

A 66-year-old woman, who had had bronchial asthma, was admitted to our hospital because she suffered from fever, productive cough, wheezing, dyspnea, and chest pressure sensation.

Her chest X-ray showed migrating infiltration and marked cardiomegaly. Her ECG at the admission revealed abnormal Q wave and T wave inversion, though that of 3 years before had been almost nor-mal. Hematology showed leukocytosis and eosino-philia of 8,000/mm3 without abnormal cells. All immunological tests were negative and the specific cause of the eosinophilia was unknown.

2 weeks after admission, she complained of severe chest pain suddenly and her ECG showed ST eleva-tion on V1-4 and serum CPK level was elevated to 290 IU/l.

By the thrombolytic agent and anticoagurant therapy, her symptom was lightened immediately.

2 months later, we made her cardiac catheteriza-tion and myocardial biopsy. Her LVG showed a small aneurysm of the apex, though her CAG was normal finding. The biopsy revealed moderate fib-rosis and cellular infiltration including a few eo-sinophils. We thought that eosinophilic endocarditis had existed first, and secondary embolism continued led to the small infarction.

The hypereosinophilia was spontaneously norma-lized 2 months after admission, but the patient complained of myalgia and sensory disturbance of extremities. The biopsy of quadriceps muscle could prove neither infiltration of eosinophils nor vasculi-tis. But we diagnosed mononeuritis multiplex due to hypereosinophilia.

Judging from various symptoms and laboratory findings, this case was included to the hypereosino-philic syndrome. We also thought allergic granulo-matosis and angitis as one of the differential diagno-ses, but histologically vasculitis was not proved.

In this case, eosinophilia was disappeared without using corticosteroids. This progress is rare and very interesting and careful following is thought to be necessary.
