Case Report: Gelastic Seizures in a Young Boy: Evaluation by Magnetic Resonance Imaging

Objective: 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. Conclusion: This report shows that neuroimaging should be performed on patients with gelastic seizures to exclude any underlying structural lesion of causal significance.
