Abstract
BACKGROUND: When administered to an immune-compromised patient, BCG (Bacille Calmette-Guérin) can cause disseminated and life-threatening infections.
OBJECTIVE: To describe the imaging findings in children with primary immunodeficiency and BCG-related infections.
MATERIALS AND METHODS: We reviewed the imaging findings of children with primary immunodeficiency treated at a children’s hospital during 2012-2014 with localized or disseminated BCG infection. Imaging modalities included US, CT and radiography.
RESULTS: Nine children with primary immunodeficiency had clinical signs of post-vaccination BCGitis; seven of these children showed disseminated disease and two showed only regional lesions with characteristic ipsilateral lymphadenopathy. Overall, lymphadenopathy was the most prevalent feature (n = 8) and characteristically appeared as a ring-enhancing hypodense (CT) or hypoechoic (US) lesion. Visceral involvement with multiple abscesses appeared in the spleen (n = 2), liver (n = 1) and bones (n = 1). All lesions regressed following appropriate anti-tuberculosis treatment.
CONCLUSION: BCG infection needs to be considered in children with typical findings and with suspected primary immunodeficiency.
