Computed tomography in intracranial cysticercosis

Area of Science:

• Neurology
• Radiology
• Infectious Diseases

Background:

• Cerebral cysticercosis is a parasitic infection of the brain caused by the larval cysts of the tapeworm Taenia solium.
• Accurate diagnosis relies on identifying characteristic imaging findings.

Observation:

• A review of computed tomography (CT) scans and radiographic studies from 23 patients with cerebral cysticercosis was conducted.
• The study focused on the imaging characteristics of parenchymal calcifications, ventricular cysts, and subarachnoid cysts.

Findings:

• Parenchymal calcifications, the most frequent finding, are more discernible on CT scans compared to skull films.
• Disproportionate ventricular enlargement may indicate ventricular cysts.
• Subarachnoid cysts are best detected using a combination of CT and pneumoencephalography.
• Contrast enhancement was absent in cisternal and ventricular cysts but potentially present in parenchymal lesions.

Implications:

• CT imaging is crucial for diagnosing cerebral cysticercosis, particularly for detecting parenchymal calcifications.
• Combined imaging modalities like CT and pneumoencephalography improve the detection of cysts in different brain compartments.
• Understanding contrast enhancement patterns aids in differentiating lesion types.
