Unusual Presentation of Multi-organ Hydatid Cysts in a Child

A 9-year-old boy presented to the pediatric clinic with symptoms of headache, left-sided diplopia, impaired speech, and nausea. His leukocyte count was 14100/μL with eosinophilia of 3050/μL (21.7%). Cranial magnetic resonance imaging revealed the presence of a cyst measuring 7×6 cm in the left parietal region with some mass effect over the adjacent structures and minimal perilesional edema. The lesion was solitary, homogeneous, and spherical with well-defined borders and no contrast enhancement (Figure 1a).
