Pure Sensory Stroke Caused by a Pontine Infarct:Clinical, Radiological, and Physiological Features in Four Patients Stroke 25:1512-1515, Shintani,S.,et al, 1994 See this aricle in Pubmed Article Abstract Lesions were localized in the medial lemniscus of the middle and lower pons,with a sparing of the spinothalamic tracts.The central condition times of short-latency somatosensory evoked potentials were prolonged (patients 1,2,and 4),and the amplitudes were significantly reduced (patients 1 and 2)when stimulating the paresthetic-sided median nerve (contralateral side of the lesion)compared with stimulating the other side.In all cases,the clinical and radiological findings indicated a dysfunction of the medial lemniscal tract in the pons.The observed somatosensory evoked potentials were probably related to the persistent refractory dysesthesias present in these patients.
