Isolated Pontine Infarctions with Prominent Ipsilateral Midfacial Sensory Signs Stroke 28:649-651, Masjuan,J.,et al, 1997 See this aricle in Pubmed Article Abstract Pontine infarctions can produce diverse sensory features.Ipsilateral midfacial sensory defect has been rarely reported.The clinicoanatomic basis for the ipsilateral midfacial sensory defect described is unknown. Involvement of the dorsal trigeminothalamic tract or fiber tracts related to central regions of the face,located in the medial part of the midbrain, could help to explain these data.The symptoms could be due to direct damage or to edema resulting from the infarct.In some patients,midfacial sensory complaints,particularly of the ala nasi,could be an early sign of major pontine deficits and may be important to determine appropriate treatment.
