Posterior fossa tumors with pathological laughter
A. N. Achari and J. Colover
Of two patients with posterior fossa tumor and pathological laughter, one
had extrinsic compression of the brain stem; the other had an intrinsic
brain-stem lesion. Surgical removal of the epidermoid from the
cerebellopontine angle cured the laughter. The euphoria of multiple
sclerosis with paroxysmal laughter and a feeling of joy is to be
differentiated from cases in which pathological laughter is a presenting
complaint.
