title: Hemichorea resulting from single enhancing computed tomography lesion.
abstract: A single small enhancing computerized tomographic lesion is a common finding in Indian patients with seizures, particularly focal seizures. A small single enhancing computed tomography lesion also presents with varied non-epileptic manifestations viz. focal neurological deficits, episodic vascular headache, syndrome of increased intracranial pressure, etc. Here we present a case of hemichorea resulting from single enhancing CT lesion. A 12-year-old female presented with acute onset abnormal movements involving right side of body. A clinical diagnosis of right hemichorea was made and patient was subjected to neuroimaging along with other investigations. CT scan showed a single ring-enhancing lesion with perifocal edema in left thalamic area suggestive of neurocysticercosis. Patient was treated with albendazole, steroids and haloperidol therapy. Patient showed marked improvement at follow-up after one month. Repeat CT scan revealed resolution of lesion. This case has been reported because hemichorea in young female is usually caused by post-streptococcal infection and it is quite rare presentation of small ring enhancing lesion.
