Dynamic scans with IV gadolinium show gross level 1, 2 and 3 right axillary lymphadenopathy with smaller left sided axillary lymphadenopathy. Breasts are normal.
Case Discussion
Yellow fever vaccine is a weakened live virus and is associated with systemic flu-like symptoms. Lymphadenopathy can occur. Follow-up ultrasound and biopsy of these lesions after 2 weeks showed reduced size of the nodes and "reactive" change on cytology. It is important to obtain a complete history or even talk with the patient when interpreting any radiological examination in order to avoid false positive results.
