Diagnosis of cystic echinococcosis within a pediatric hospital setting

The diagnosis of early echinococcosis may be difficult due to the small lesion size in the first years of infection and nonspecific symptoms. Here, we discuss a case of cystic echinococcosis at a pediatric center to highlight the challenges in identifying this parasitic disease.

A young female presented to a pediatric hospital with vague abdominal symptoms and an exposure history that aligned with potential echinococcosis. Ultrasound imaging of the liver identified a mixed hyper/hypo-echoic cystic lesion. However, with a negative echinococcal serology result, echinococcus was deemed less likely, and lesion fine-needle aspiration was performed. Cystic echinococcus was confirmed on cytopathology, with features pathognomonic for hydatid cyst. The aspiration procedure did not incur complications; however, the case demonstrates the importance of multifaceted interpretation of infectious testing for echinococcus.

This case highlights the important features of echinococcosis, including the epidemiology, optimal laboratory testing, and management of this complex infection with significant clinical sequela.
