A 77-year-old female presented to our clinic with a mass in the right axilla. Coronal (Panel A) and axial (Panel B) T2-weighted MR images reveal a multiseptated cystic lesion solely in the right axillary fossa. Axial pre- (Panel C) and post-contrast (Panel D) T1-weighted MR images show multiple cysts with peripheral enhancement of their walls following gadolinium administration.
Although extremely rare, clinicians should include hydatid disease in the differential diagnosis of palpable axillary mass lesions in endemic regions.
