A Review of 5 Patients with Pure Sensory Stroke Syndrome

Pure sensory stroke (PSS), first described by Fisher in 1965, is a clinical condition characterized by numbness and paresthesia of the face, arm and trunk on one side, in absence of other neurologic deficit. PSS could arise anywhere along the sensory system from the cerebral cortex to the medulla. The authors experienced 5 patients with PSS: one patient had a hemorrhage on the thalamocortical pathway including the internal capsule and the corona radiata. Two another had thalarnic lesions. The fourth had a pontine hemorrhage with perioral onionpeel distributed face sensor- involvement. And the last had a pontine lacune involving crossed trigeminothalamic tract and lateral spinothalamic tract.
