Very few cases of pulmonary vasculitis that cannot be classified into a single category of vasculitis have been described. We report the first case of a vasculitic process in which pulmonary involvement with asthma, eosinophilic interstitial infiltrates, and small nodules were seen in association with jaw claudication and temporal arteritis with giant cells found on biopsy. Other signs of systemic involvement were also present such as peripheral neuropathy, hematuria with erythrocytic casts and proteinuria, pericardial effusion, and a dilated cardiomyopathy. The histopathologic picture was complex and unique. The early age of onset, the multisystemic involvement, and the prompt response to cyclophosphamide pointed to a diagnosis of "polyangiitis overlap syndrome," with some aspects of Churg-Strauss syndrome and also temporal arteritis. Physicians should be aware of these polymorphous and life-threatening pulmonary vasculitic syndromes, which require aggressive immunosuppressor therapy.

This study was made to evaluate the usefulness of various non-invasive methods such as electrocardiography, echocardiography and 201T1 myocardial scintigraphy in the differential diagnosis of idiopathic congestive cardiomyopathy (CCM) and ischemic heart disease (IHD). Eighteen cases with CCM and 9 cases with IHD were subjected. For this study patients with IHD showing dilated cavity (LVDd over 66 mm) and diffuse hypokinesis of the left ventricle in the echocardiogram were selected. For echocardiographic study, cross-sectional sector-scan instrument, Toshiba SSH-11A was used, and 201T1 myocardial scintigraphy was performed using Toshiba jumbo gamma camera GCA-401. Cardiothoracic ratio of CCM and IHD were 59.6 +/- 6.3% and 58.3 +/- 6.3% in average, respectively. In CCM, mean LVDd was 76.0 +/- 5.6 mm and mean LVDs was 63.4 +/- 7.3 mm. In IHD, mean LVDd was 74.7 +/- 8.1 mm and mean LVDs as 63.2 +/- 4.6 mm. Both cardiothoracic ratios and echocardiographic findings showed no difference between CCM and IHD. Incidence of an abnormal Q wave in ECG was higher in IHD (2.72 leads per a case) than that in CCM (1.33 leads per a case). An abnormal Q wave in aVL was frequently (28%) observed in CCM but none in IHD. However, these ECG findings did not seem to be contributory to the differential diagnosis. Myocardial scintigraphic study revealed that 10 of 18 cases with CCM showed no perfusion defect or sparse uptake and others showed small and isolated defect in the apex or postero-lateral wall of the left ventricle, while 7 of 9 cases with IHD showed large perfusion defect over 15% in the anterior and inferior areas. However, small localized defects less than 14% in the apex were observed in both groups, 5 cases (27.8%) with CCM, and 2 cases (22.2%) with IHD, suggesting limitation of this method for the differential diagnosis.
