Crossed aphasia is characterized by an acquired language disorder caused by a right hemispheric lesion, with a prevalence of 1% - 2%.
The authors present a case report of a 69-year-old male, right-handed, with multiple cardiovascular risk factors.
Asymptomatic until September 28, 2017, when suffered a language change and left-sided motor deficit. Admitted to the emergency department, where he performed a brain imaging study that showed right hemispheric ischemic lesions. He underwent intravenous thrombolysis and mechanical thrombectomy. Worsening of the neurologic deficits, 24 hours after the beginning of the clinical picture, reason why he repeated the brain imaging study that showed right middle cerebral artery (RMCA) infarction.
Admitted in a stroke unit and later in the in-patient department of Physical and Rehabilitation Medicine. At the initial evaluation, in addition to the left motor deficit, he presented language changes evidencing characteristics of global aphasia. He was integrated into a rehabilitation program, with a slow evolution of the aphasic and motor picture.
The prognosis of crossed aphasia is related to the location and severity of brain injury. Due to the extension and severity of the lesion of the patient we expect a clinical slow evolution/stabilization.
