Prednisolone-responsive headache in patients with solitary cysticercus granuloma and seizures.

BACKGROUND

Solitary cysticercus granuloma is the commonest imaging abnormality in Indian patients with new-onset seizures. Few patients, in addition, complain of disabling headache.

OBJECTIVE

To report our experience of 16 patients with new-onset headache, seizures, and solitary cysticercus granuloma.

METHODS

Sixteen consecutive patients, who had moderate to severe new-onset headache and fulfilled the diagnostic criteria of solitary cysticercus granuloma, were included in the study. The inclusion criteria were: occurrence of seizures, minimal or no neurologic deficit, absence of papilledema, no evidence of any systemic disorder, and computed tomography showing a single ring/disk-enhancing lesion of <20 mm in diameter. Patients received antiepileptic monotherapy, oral analgesics, and prednisolone (1.5 mg/kg/day for 7 days). Prednisolone was then tapered over the next 7 days. Patients were followed for 6 months. Follow-up computed tomography was performed after 2 months; in all 16 patients, the scans showed complete disappearance of the lesion.

RESULTS

After 14 days (at first follow-up), all patients reported significant improvement in headache. Follow-up after 2 months revealed that all patients were headache-free. None of the patients reported any recurrence of headache.

CONCLUSIONS

This open-label study suggests the effectiveness of prednisolone for disabling headache in Indian patients with solitary cysticercus granuloma and seizures. There is a need, however, for more scientifically rigorous studies for further confirmation of our results.
