Breast Sparganosis Mimicking Ipsilateral Breast Tumor Recurrence in a Patient with a History of Breast Conserving Surgery: A Case Report

Abstract

Sparganosis is a rare parasitic infection caused by ingesting plerocercoid larvae in impure water or consuming raw intermediate hosts such as frogs and snakes. The breast is a rare site of infection. Breast sparganosis usually presents as a migrating subcutaneous mass that clinically and radiologically mimics malignancy. Herein, we report a surgically confirmed case of breast sparganosis mimicking ipsilateral breast tumor recurrence (IBTR) in a patient with a history of breast conserving surgery (BCS) for breast cancer with multimodal imaging findings.
