PURPOSE: To compare the high-resolution CT features of bleeding foci in patients with massive hemoptysis during embolization with those revealed by angiography. MATERIALS AND METHODS: Between June 1997 and June 1999, we evaluated 25 patients who from among a total of 49 with arterial embolization due to massive hemoptysis underwent HRCT prior to embolization. We retrospectively analyzed medical records, and angiographic and HRCT findings. The time interval between HRCT and arterial embolization varied from two hours to six days. Angiography indicated that the bronchial, intercostal and internal mammary artery, and branches of the subclavian, were the foci of bleeding, and indicated the location of these in each pulmonary lobe. The HRCT findings were evaluated in terms of cavity, air-meniscus sign, bronchial dilatation, consolidation, ground-glass opacity, and fibrotic scar. We analyzed the corresponding sites of HRCT and the angiographic findings of the foci of bleeding. RESULTS: In 24 of 25 patients, the foci of bleeding were angiographically confirmed, their presence being noted in 28 pulmonary lobes. HRCT findings corresponding to the bleeding foci revealed by angiography were the air-meniscus sign (8 of 10 lobes, 80.0%), cavity (7 of 9 lobes, 77.8%), bronchial dilatation (21 of 30 lobes, 70.0%), and fibrotic scar (1 of 23 lobes, 4.3%). The findings in areas of consolidation and/or ground-glass opacity only did not correspond, however. CONCLUSION: As compared with those revealed by angiography, the HRCT features of bleeding foci in patients with massive hemoptysis during embolization are in order of frequency, the air-meniscus sign, cavity, and bronchial dilatation.

Phlebectasia is an abnormal dilatation of an isolated vein and a rare venous anomaly and is usually asymptomatic. Clinically internal jugular phlebectasia is a self limited benign condition and usually no treatment is required after initial diagnosis. So suspection of this disease and appropriate diagnostic approaches are essential to avoid unnecessary surgical intervention. We present three cases of internal jugular phlebectasia of which diagnosis was made by neck sonography and CT.

Curry powder is widely used in various dishes. It is a mixture of 20-50 kinds of natural spices made from the leaves and seeds of plants. Although there have been some reports of allergy caused by inhalation of spices in western countries, while there are no reports of occupational allergy caused by spices in our country. We report a patient with rhinitis and asthma induced by exposure to spice dusts in a curry industry. A 32-year-old man developed rhinorrhea, sneezing and coughing three years prior to visiting our hospital. Since 10 years ago, he has been involved in grinding and mixing spices in a curry industry. Total peripheral eosinophil count was 400/mm3 and serum total IgE level was 163 IU/ml. Allergy skin-prick test showed positive responses to mugwort (3+), D. farinae (3+) and celery (3+), while serum specific IgE detected by RIA (DPC, LA, CA) showed all negative results. Skin-prick test to four kinds of spice extractscelery seed, fennel, cumin and coriander-showed strong positive responses. Bronchoprovocation test with celery seed extract (1:10 v/v) showed an early asthmatic response. Specific IgE and IgG4 antibodies to celery seed and the other three spices were detectable by ELISA. IgE-ELISA inhibition test using each spice antigen showed significant inhibitions. In conclusion, IgE-mediated mechanism may be involved in the pathogenesis of curry powder-induced bronchoconstriction in an exposed worker. Further studies will be needed to investigate the role of specific IgG4 in pathogenesis of bronchoconstriction in curry powder-induced asthma.

Congenital pulmonary vein stenosis (CPVS) with an anatomically normal connection is a rare cardiac malformation. This cardiac anomaly usually is accompanied by other cardiac abnormalities. Bilateral CPVS is a more severe form of a CPVS and it usually leads to progressive pulmonary hypertension and death if it is not treated. Here, we report a patient with a history of cough, tachypnea and hemoptysis and suspected CPVS due to an abnormal thoracic roentgenogram with dilated right pulmonary arteries and pulmonary cornus. The two-dimensional and color Doppler echocardiography demonstrated three stenosed pulmonary veins connected to the left atrium. However, the fourth vessel could not be visualized. There were no other cardiac malformations associated with the CPVS. The Technetium-99m macro-aggregate lung perfusion scan showed absent or diminished perfusion to the affected lobes of the lungs. In addition, the chest computed tomography with angiogram and cardiac catheterization confirmed the findings of the echocardiogram.
