Abstract:
PURPOSE: To evaluate the ultrasonographic findings of BCG lymphadenitis complicated by BCG vaccination in children MATERIALS AND METHODS: Ultrasonography was performed for 22 cases of BCG lymphadenitis in 21 patients who were diagnosed by clinical (n=10) or pathological (n=11) examinations. Their age ranged from 4 months to 3 years (mean age; 14 months). We retrospectively analyzed the ultrasonographic findings for location, multiplicity, size, shape, margin, echogenecity, posterior enhancement, calcifications, inner anechoic portion and Doppler pattern of the BCG lymphadenitis. RESULTS: The BCG lymphadenitis was found at the axillary area in 15 cases (68%) and at the supraclavicular area in 7 cases (32%). There were ten cases (45%) of solitary lesion and 12 cases (55%) of multiple conglomerated lesions. The maximum diameter ranged from about 0.9 cm to 3.2 cm. The BCG lymphadenitis showed as round (82%), well defined (86%), or heterogeneous hypoechoic (68%) lesions with posterior enhancement (78%). Calcifications were found in 6 cases (27%) and 5 cases (83%) had been vaccinated more than 5 months ago. There were eccentric inner anechoic portions in 16 cases (73%), which were pathologically confirmed as having caseating necrosis. There were increased Doppler flow patterns in 15 cases (68%); 4 cases (18%) were of the central type, 6 cases (27%) were of the peripheral type and 5 cases (23%) were of mixed type. CONCLUSION: BCG lymphadenitis is frequently located at the axillary area adjacent to a vaccination site. The ultrasonographic findings of BCG lymphadenitis are well-defined, round, heterogeneously hypoechoic lesions with posterior enhancement, calcifications and inner eccentric anechoic portion.
