Background: Pediatric cerebral sparganosis has been seldom reported. In the current study, we retrospectively reviewed the clinicopathologic records of 9 consecutive pediatric cases of cerebral sparganosis and analyzed their epidemiologic characteristics and clinical outcomes.
Methods: Our cases included 6 boys and 3 girls, all from rural areas, and their median age at diagnosis was 9.4 (range, 5.8-12.9) years. The median duration of symptoms from onset to definite diagnosis was 21 months (range, 1 week to 3.7 years).
Results: Enzyme-linked immunosorbent assay revealed that serum anti-sparganosis antibody was positive in 9 of 9 patients and cerebrospinal fluid anti-sparganosis antibody was positive in 4 of 6 patients. Eight patients underwent craniotomy the removal of worms. The patients also received oral praziquantel. They were followed up for 2.2 years to 4.4 years. One patient died, and 8 patients survived. Three cases had poor outcomes whereas the outcome of the remaining 5 cases was satisfactory.
Conclusions: Children are more at risk for sparganosis and cerebral sparganosis may be missed because of unclear epidemiologic history and nonspecific manifestations. Cerebrospinal fluid eosinophil counts and enzyme-linked immunosorbent assay for anti-sparganosis antibody and computed tomography/magnetic resonance imaging scans may be relied on for an early and accurate diagnosis before surgery.
