Non-epileptic manifestations in patients with single enhancing computed tomography lesions.

OBJECTIVES AND METHODS

Single enhancing lesions are common computed tomographic (CT) abnormality in patients with epilepsy. In this series we are reporting 13 unusual cases with varied non-epileptic neurological manifestations in patients with ring or disk enhancing CT lesions.

RESULTS

Acute, stroke like non-vascular focal neurological deficits (hemiparesis in four patients, and crural monoparesis, Broca's aphasia, homonymous hemianopia, hemichorea in one patient each) were frequent non-epileptic manifestations. Episodic vascular type of headache was seen in three patients, one patient had headache because of raised intracranial pressure. One patient presented with acute confusional state. All these patients were treated symptomatically, and with oral corticosteroids. CT lesions disappeared in 8-12 weeks time in all patients except in one patient with chorea where the lesion calcified. Significant clinical improvements were noted in all the patients.

CONCLUSIONS

Several non-epileptic manifestations can also be associated with single enhancing CT lesions, and like epileptic disorders these disorders also have a benign course. Corticosteroids, probably, hasten the clinical improvement and produce early resolution of the CT lesions.
