[Abstract]Objective：ToevaluatethediagnosticvalueofultrasonographyforBCGvaccinationrelatedlymphadenitis（BCG-itis）. Methods：Aretrospectiveanalysiswasperformedontheultrasonographicfeaturesof28infantsofpathologicallyconfirmed BCG-itisintheaxllaryregion.Thelong-axistoshort-axisratio，morphology，margins，hilumandblodflowpattesofthe pathologicallymphnodeswereobserved，thentheregionalclasificationandtypingwereperformed.Results：All28casswere single，with18casesontheleftsideand1Ocasesontherightside.Exceptfor1caseofskinscar formationafter healing， thelesion distributionof theremaining 27cases was determinedbythe Level zoning method，24 cases（ 88.9% ）were located under the armpit，and 3 cases（ .11.1% ）were in the armpit.According to the ultrasound manifestations and pathological developmentprocess，the28cases wereclassifiedintothelymphadenitistype（2Ocases，71.4%），thecaseousnecrosis type（5cases，17.9%），theabscessinus tracttype（2cases，7.1%）andthehealingscartype（1case3.6%）.Exeptforone caseofthehealingscartype，thebloodflowdistributionpatermsinthelesion lymphnodesoftheremaining27cases werecentraltypein15cases，peripheraltypein4cases，andmixedtypein8cases.Conclusion：Ultrasonographyeffectively visualizesthemorphologicaldiversityandevolutionarystagesofBCG-itisintheaxillryregionofinfants，stablishingtsole asthe primary imaging modality for this condition.
