Spontaneous Cortical Intracerebral Hemorrhage Causing Ipsilateral Hand and Oral Sensory Change Without Motor Deficit: A Case Report

Intracerebral hemorrhage (ICH) is the second most common stroke subtype associated with high morbidity and mortality rates. Although various brain regions are susceptible to ICH, putaminal hemorrhage is the most common, whereas cortical ICH is less common. Here, we report the case of a 69-year-old man who developed a parietal cortical ICH. The patient developed hypoesthesia and paresthesia in the right upper lip and hand; however, the weakness was not severe. Twenty-five days after the ICH onset, the manual muscle test results were normal, but he had difficulty eating and shaving because of decreased hand dexterity. The rehabilitation focused on improving fine hand motor function and endurance. On the 94th day after ICH onset, paresthesia remained only in the fingertips, and the upper lip sensory change disappeared. Patients with sensory symptoms in the perioral area, hands, and brain lesions were previously referred to as having cheiro-oral syndrome (COS). With the advancement of neuroimaging, the use of this term has decreased, as cerebrovascular events can explain patient symptoms in correlation with neuroanatomy, etiology, and pathogenesis. We report a patient with cortical ICH, also known as COS, which is a stroke syndrome with a good prognosis.
