Lenticulocapsular hemorrhages presenting as pure sensory stroke

Pure sensory stroke (PSS) syndrome is most often produced by a small infarct involving the lateral thalamus, Larger than lacune-sized putaminal hemorrhages have not been considered as a cause of this syndrome, The author describes 3 patients with hypertensive lenticulo-capsular hemorrhage presenting with hemisensory symptoms without any other neurological deficits, In these patients, the sensory symptoms were more marked and persistent in the legs than in the other body parts, Neuroradiological data suggested that thalamocortical sensory pathways were exclusively involved. These patients highlight the heterogeneity of the vascular lesion producing PSS syndrome and illustrate that a putaminal hemorrhage should be included in the differential diagnosis of this clinical syndrome.
