Toxocariasis Mimicking Lymphoma and Presenting as Multiple Lymphadenopathy: A Case Report

  • 1Department of Radiology, Korea University Guro Hospital, Seoul, Korea. cminpark@korea.ac.kr


Toxocariasis, a parasitic infection, causes hyper eosinophilia resulting in radiological presentation of eosinophilic infiltrations in the involved organs. In the abdomen, toxocariasis has been reported to manifest as infiltrations in the liver or in the gastrointestinal tract, but it is known to be uncommon to manifest as multiple lymphadenopathy. There have been two case reports of toxocariasis presenting as generalized lymphadenopathy in the chest, neck and inguinal regions. To the best of our knowledge, generalized conglomerated lymphadenopathy occurring mostly in the abdomen from toxocariasis has not been published in the English literature. Herein, we report a rare case of toxocariasis presenting as multiple conglomerated lymphadenopathy mimicking lymphoma on CT.

  • Fig. 1 A 43-year-old female with multiple lymph node enlargements detected in abdomen and pelvis CT A. Coronal image of contrast enhanced CT shows homogenous enhancing conglomerated lymph nodes (asterick) in the abdomen. No abnormal focal lesions are noted in the liver parenchyma. B. Contrast enhanced abdomen and pelvis CT axial view shows multiple conglomerated lymph nodes (asterick) in the abdomen showing sandwich sign around the mesenteric vessels. C. Axial image of initial chest CT shows left axillary lymphadenopathies. This scan also shows enlarged right axillary and bilateral cervical lymph nodes (not shown in this image). D. PET-CT shows high metabolic uptake in multiple abdominal lymph nodes. E. Four months follow-up CT shows marked decreased sizes oflymph nodes. F. Photomicrograph of biopsy specimen from left axillary lymph node and bone marrow shows inflammatory cell infiltrations predominantly composed of eosinophil granulocytes (arrows) (hematoxylin and eosin stain, × 12.5, × 400). CT = computed tomography, PET = positron emission tomography
