We report a young woman suffering brief painful episodes in her right arm which sometimes spread to the whole right side of her body. The episodes were initially rare, but over 13 months they became increasingly frequent until occurring every 20 min. Neurological examination was normal. Magnetic resonance imaging revealed a lesion in the white matter of the parietal operculum. Lesions in the parietal operculum associated with persisting thalamic pain or loss of pain sensation have been reported, but rarely with episodic pain. Since episodic painful attacks have been described in association with various suprathalamic lesions, we conclude that paroxysmal pain attacks may be another consequence of the disturbance of the normal pattern of thalamocortical connections to the second sensory cortical area by a lesion, in our case, of the subcortical area of the parietal operculum.
