Background And Purpose:
The purpose of this study was to analyze the computed tomography (CT) and magnetic resonance imaging (MRI) features of cerebral sparganosis to improve the accuracy of diagnosing cerebral sparganosis with medical imaging modalities.
Materials And Methods:
This was a retrospective study of CT and MRI features of 12 patients with cerebral sparganosis. A comparative analysis between imaging findings, and intraoperative and postoperative pathological findings was performed.
Results:
A total of 20 lesions were observed in 12 patients with 5 patients having a solitary lesion. CT and MRI imaging showed worm-body sign in 5 patients (41.7%), tunnel-sign in 5 patients (41.7%), migration sign in 7 patients (58.3%), worm-shaped enhancement in 4 patients (33.3%), bead-shaped or ring-shaped enhancement in 5 patients (41.7%), irregular or nodular enhancement in 3 patients (25%), meningeal enhancement in 2 patients (16.6%), intracranial hemorrhage in 2 patients (16.6%), brain parenchymal edema in 10 patients (83.3%), cerebral white matter degeneration in 11 patients (91.7%), negative mass effect in 10 patients (83.3%), and punctuate calcification in 3 patients (25%). Among the 4 patients with live worm, CT and MRI showed worm-body sign in 3 patients (75%), tunnel-sign in 3 patients (75%), migration sign in 3 patients (75%), and worm-shaped enhancement in 2 patients (50%).
Conclusion:
Cerebral sparganosis with live worm exhibits several distinguishing imaging characteristics, which reflect the pathological changes and can improve the diagnosis of cerebral sparganosis.
Insights
Computed tomography (CT) and magnetic resonance imaging (MRI) reveal distinct features of cerebral sparganosis, aiding in accurate diagnosis. Live worm presence shows unique imaging characteristics for improved detection.
Area of Science:
- Neurology
- Radiology
- Parasitology
Background:
- Cerebral sparganosis is a rare parasitic infection of the brain.
- Accurate diagnosis is crucial for effective treatment.
Purpose of the Study:
- To analyze computed tomography (CT) and magnetic resonance imaging (MRI) features of cerebral sparganosis.
- To improve diagnostic accuracy using medical imaging modalities.
Main Methods:
- Retrospective analysis of CT and MRI features in 12 patients with cerebral sparganosis.
- Comparative analysis of imaging findings with intraoperative and postoperative pathological findings.
Main Results:
- Common imaging findings included worm-body sign, tunnel-sign, and migration sign.
- Brain parenchymal edema (83.3%) and white matter degeneration (91.7%) were prevalent.
- Live worm presence correlated with specific signs like worm-body, tunnel, and migration signs.
Conclusions:
- Cerebral sparganosis with live worms presents characteristic imaging features.
- These features can significantly enhance diagnostic accuracy.
- CT and MRI are valuable tools for diagnosing cerebral sparganosis.
