We identified 10 patients with acute pontine infarction and specific sensory findings.Two patients had pure sensory symptoms,two had sensory complaints of the hand and mouth,and the other six had hemisensory loss referable to medial lemniscal or spinothalamic tract dysfunction but localized to one limb,to an arm and leg,or to the face,characteristic of stroke localized to the cerebral hemisphere.All patients had magnetic resonance imaging showing infarction of the medial or lateral pontine tegmentum and a patent basilar artery.No definite source for cardiogenic thromboembolism was found.Infarcts in the midline extending from the base of the pons posteriorly into the tegmentum suggested basilar branch occlusion,while infarcts involving only part of the tegmentum probably resulted from small penetrator branch occlusion.Vertigo,light-headedness, or cranial nerve dysfunction suggested a pontine location of neurological dysfunction in these patients,but the nature of the sensory findings did not always predict the lateral,medial,inferior,or superior extent of tegmental infarction. |
