RESUMEN
A 33-year-old male presented with involuntary and inappropriate laughter. Neuroimaging revealed a meningioma ventrolateral to the pons and midbrain, attached to the medial middle tentorium on the left side. The pathological laughter ceased immediately after subtotal removal of the tumor. Pathological laughter may be an early focal sign of a mass compressing ventrolateral brainstem.

A 3-year-old boy presented with an unusual consciousness disturbance accompanied by involuntary movement disorder after radical surgical removal of a huge hypothalamic glioma. Postoperative computed tomography and magnetic resonance imaging revealed a lesion in the bilateral basal ganglia. Marked neurological improvement was obtained by treatment with dopamine agonists, suggesting that the disruption of the dopaminergic pathway via the hypothalamus was the cause of these neurological symptoms.
