Migration characteristics as a prognostic factor in cerebral sparganosis

Area of Science:

• Neuroparasitology
• Infectious Diseases
• Radiology

Background:

• Cerebral sparganosis is a rare parasitic infection of the brain.
• Understanding diagnostic and prognostic factors is crucial for patient outcomes.

Purpose of the Study:

• To differentiate diagnostic and prognostic factors in cerebral sparganosis.
• To analyze clinical, radiographic, treatment, and outcome data.

Main Methods:

• Retrospective analysis of 30 cerebral sparganosis patients (2010-2018).
• Evaluation of clinical manifestations, MRI features, treatment, and outcomes.
• Identification and classification of parasite migration patterns.

Main Results:

• Four distinct migration modes identified: interlobar, transmidline, transventricular, and cerebellum-brainstem.
• Higher good outcome rates in patients with successful live worm capture (75.0%).
• Preoperative antiparasitic medication correlated with migration to the cortical surface, increasing live worm capture probability.

Conclusions:

• Proposed four sparganosis migration modes linked to worm capture and prognosis.
• Preoperative medication enhances worm migration and capture, suggesting novel therapeutic significance.
• Findings aid in optimizing management strategies for cerebral sparganosis.
