Ultrasound findings in children with toxocariasis: report on 18 cases

Pediatr Radiol. 1999 May;29(5):316-9. doi: 10.1007/s002470050596.

Abstract

Purpose: To evaluate abdominal ultrasound (US) findings in children infected with Toxocara canis.

Materials and methods: Eighteen children, 18 months to 7 years of age, with serological diagnosis of T.canis infection underwent abdominal US. Eosinophil counts, hemoglobin levels and immunoglobulin E titers were measured for all patients.

Results: Abdominal ultrasound revealed multiple hypoechoic areas in the livers of 15 patients (83.3%). Hepatohilar lymph-node enlargement was present in 14 patients (77.7%), 2 of whom also showed peripancreatic lymph-node enlargement. Hepatomegaly was present in 13 patients (72.7%) and splenomegaly in 9 (50%).

Conclusion: The most prevalent findings of abdominal ultrasound examination of children with T.canis infection are hepatic granulomas and abdominal lymph-node enlargement. This infection should be considered in the differential diagnosis of any children who exhibit these findings on abdominal US examination, especially for those with eosinophilia.
