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.
