볼거리 의심환자의 초진에서 경부 초음파의 유용성

Objectives: To compare the accuracy of diagnosis in mumps patients between using salivary gland ultrasound (US) and physical examination (PE). Subjects and Methods: The medical records of 72 patients who suspicious for mumps at first medical examination [36 patients were performed with ultrasound (US), 36 patients without ultrasound (PE)] were reviewed. Results: There was no significant difference in sex ratio and mean age between US and PE. In US group, 6 patients were suspicious for other disease or normal gland by ultrasound. Among them, 1 patient of was diagnosed finally with mumps. Among another 30 patients who were suspicious for mumps, 28 patients was diagnosed with mumps (sensitivity 96.6%, specificity 71.4%, positive predictive value 93.3%, negative predictive value 83.3%, accuracy 91.7%). In PE group, 2 patients were suspicious for normal, but all of them finally was diagnosed with mumps finally. Among another 34 patients who were suspicious for mumps, 21 patients were diagnosed with mumps (sensitivity 58.3%, specificity 0%, positive predictive value 61.8%, negative predictive value 0%, accuracy 58.3%). There was a significant difference in sensitivity (p<0.05), specificity (p<0.05), positive predictive value (p<0.05), negative predictive value (p<0.05) and accuracy (p<0.05). All ultrasound was performed at the same day of initial visit. It takes 2.3 day to get the blood test result. Conclusions: Salivary gland ultrasound in the patients who were suspicious for mumps could be used for improving the accuracy of diagnosis in mumps patient at the first medical examination.
