Cat-scratch disease (Bartonella henselae). A 59-year-old woman had a 1-month history of a left axillary mass. Ultrasound-guided biopsy showed follicular hyperplasia with non-necrotising epithelioid granulomas. B. henselae (cat-scratch disease) titre was more than 1:1,024, consistent with recent infection. a Left mediolateral-oblique view with magnified image showed a new left axillary mass (arrow). b Ultrasound showed multiple enlarged lymph nodes in the left axilla with lobulated margins, thickened cortices and increased cortical vascular flow
