Summary
Single enhancing CT lesions, common in Indian epilepsy patients, can cause rare hemichorea. This case highlights neurocysticercosis as a cause of hemichorea in a young female.
Area of Science:
- Neurology
- Radiology
- Infectious Diseases
Background:
- Single small enhancing computed tomography (CT) lesions are frequently observed in Indian patients, often associated with focal seizures.
- These lesions can manifest with diverse non-epileptic symptoms, including focal neurological deficits and increased intracranial pressure.
Observation:
- A 12-year-old female presented with acute-onset right-sided hemichorea.
- Neuroimaging revealed a single ring-enhancing lesion with perifocal edema in the left thalamus, indicative of neurocysticercosis.
Findings:
- The patient received treatment with albendazole, steroids, and haloperidol.
- Follow-up after one month showed marked improvement, with repeat CT scan confirming lesion resolution.
Implications:
- This case underscores the rare presentation of hemichorea secondary to a single enhancing CT lesion, specifically neurocysticercosis.
- It contrasts with the more common post-streptococcal etiology of hemichorea in young females, emphasizing the need for thorough neuroimaging in such presentations.
