Case report demonstrates successful diagnosis and resection of an axillary hydatid cyst in an adult female, highlighting the need for accurate imaging to avoid risky biopsy.
Primary hydatid disease of the axilla is rare and mimics various soft tissue lesions. We report a 45-year-old female who presented with right axillary swelling. Ultrasonography revealed a multicystic lesion with daughter cysts and detached membrane, while computed tomography and magnetic resonance imaging further delineated its extent. All imaging findings strongly suggested a hydatid cyst. Complete surgical resection was done, and histopathology confirmed the diagnosis by laminated membrane, protoscolices, and hooklets. It is important to identify a hydatid cyst at an unusual location to avoid biopsy.
