BACKGROUND AND PURPOSE: Pure or predominant hemisensory symptoms can be seen in @entity1 with @entity64 . However, there have been no reports in which sufficient numbers of @entity1 were studied with detailed descriptions on the sensory patterns and imaging findings. METHODS: We describe 17 @entity1 presenting with pure or predominant hemisensory symptoms due to @entity64 in whom CT scan and/or MRI identified appropriate lesions. RESULTS: Eleven @entity1 had an @entity1188 and 6 had a @entity548 . Aside from sensory deficit, the majority had @entity1296 and @entity11583 . Fifteen @entity1 had paramedian dorsal pontine lesions associated with pure or predominant lemniscal sensory involvement, often in the cheiro-oral (n = 4) or leg dominance (n = 4) patterns. The lesions of the former group tended to be located more medially compared with those of other @entity1 , which is in agreement with the sensory topography of the pontine lemniscal sensory tract. Bilateral facial or perioral sensory symptoms were noted in 6 @entity1 . One @entity1 with a dorsolateral pontine lesion had selective spinothalamic modality impairment, while one with a lateral midbrain @entity1188 had sensory deficit of all modalities. CONCLUSIONS: Pure or predominant brain stem @entity64 is most often produced by small @entity1188 or @entity548 in the paramedian dorsal pontine area and may be differentiated from thalamic pure @entity64 by the following characteristics: frequent association of @entity1296 / @entity11583 , predominant @entity1109 , occasional leg dominance or cheiro-oral pattern, and frequent bilateral perioral involvement.
