Multifocal Sparganosis Mimicking Lymphoma Involvement: Multimodal Imaging Findings of Ultrasonography, CT, MRI, and Positron Emission Tomography-Computed Tomography

Abstract

Sparganosis is a rare parasitic disease caused by the migrating plerocercoid larva of Spirometra species tapeworms. The most frequent clinical manifestation is a subcutaneous nodule resembling a neoplasm. In this study, we presented multimodal findings of ultrasonography, computed tomography, magnetic resonance imaging, positron emission tomography-computed tomography and follow-up imagings on multifocal sparganosis, mimicking lymphoma involvement in a patient with lymphoma.
