Gelastic seizures in a young boy: Evaluation by magnetic resonance imaging

ABSTRACT

To present an interesting case of gelastic seizures in a child who had an underlying brain lesion. Clinical Presentation and Intervention A 10-year-old boy presented with recurrent episodes of uncontrollable laughter since the age of 6 years. Computed tomography showed a well-defined mass in the region of suprasellar and interpeduncular cisterns. Magnetic resonance imaging revealed a lesion, most likely a hamartoma, arising from the region of tuber cinerium. The lesion was subsequently resected and a marked improvement in the frequency and intensity of seizures was noted. This report shows that neuroimaging should be performed on patients with gelastic seizures to exclude any underlying structural lesion of causal significance:
