209 Possible Causes for Anisocoria, Hemiparesis

  • Stroke

    Decreased levels of consciousness, hypertension, bradycardia and anisocoria may indicate a pathological rise of intracranial pressure due to cerebral edema.[] SSEH presenting as a hemiparesis is less common and in such situations, it can be mistaken for a cerebrovascular accident (CVA).[] In the Wind chapter of Donguibogam, left hemiparesis due to stroke is called Tan, a sort of Hyeol-Byeong, and right hemiparesis due to stroke is called Tan, a sort of Gi-Byeong[]

  • Brown-Sequard Syndrome

    Neurological examination however, revealed anisocoria, his left pupil being smaller than his right, and a Brown-Sequard syndrome, with a sensory level at C6.[] Characteristic neurologic findings, including a unilateral hemiparesis with associated contralateral sensory findings, were noted at the time of presentation.[] Our patient had cervical trauma causing a Horner's syndrome as the aetiological factor for anisocoria.[]

  • Cerebral Embolism

    After the patient was moved to the recovery room, we were alerted at 20.00 that he displayed low level of consciousness, left-sided anisocoria, and decerebrate response to[] We encountered a patient with the overlapping disorders of migraine with aura, migraine-triggered seizures and recurrent transient hemiparesis caused by atypical hemiplegic[] However, the patient then developed fever, dyspnea, and subsequent right hemiparesis.[]

  • Acute Disseminated Encephalomyelitis

    Although the patient presented with anisocoria with increased intracranial pressure monitoring during hypothermia, prompt therapy with d-mannitol and dopamine was effective[] Over 48 hours, he developed aphasia, generalised hypertonia, hyper-reflexia and dense left hemiparesis.[] The patient was admitted to the Hospital del Niño in Panama City with suspected meningitis, exhibited with decreased alertness and disorientation in space and time, hemiparesis[]

  • Carotid Artery Dissection

    After initial assessment and operative management, an anisocoria was diagnosed on the intensive care unit.[] Upon treatment with anticoagulants, the patient showed significant improvement of the left-sided hemiparesis.[] A 47-year-old male presented with intermittent episodes of headache, blurry vision, anisocoria, and loss of taste sensation following a whiplash injury while body surfing.[]

  • Cavernous Sinus Thrombosis

    To describe a case of ophthalmic artery occlusion associated with anisocoria and revealing a cavernous sinus thrombosis due to sinusitis.[] A 65-year-old woman with poorly controlled diabetes presented bilateral miosis, bilateral abducens nerve palsy, and left hemiparesis.[] […] with serious sequelae, including a 30 percent mortality rate, spread of infections such as meningitis and cerebral abscesses, persistent oculomotor weakness, blindness, hemiparesis[]

  • Epidural Hematoma

    Increased intracranial pressure leads to a decline in mental status and anisocoria , in which the ipsilateral pupil is dilated.[] A 71-year-old male presented with sudden neck pain followed by left-sided hemiparesis, and was believed to have had a stroke.[] In certain cases of intracranial hypertension it might lead to Cushing triad involving respiratory depression, systemic hypertension and bradycardia. [5] Anisocoria: Unequal[]

  • Arteriovenous Malformation

    Signs and symptoms of brainstem AVMs are not specific and may include diplopia, nystagmus, dizziness, ocular motor nerve palsy, gaze palsy, anisocoria, or pupillary light–near[] […] the central lobe who underwent previous surgery for hematoma evacuation and previous radiosurgery, and whose indication for reoperation was proposed based on progressive hemiparesis[] He was being followed since the age of 8 months when the aneurysm was incidentally found during work-up for mild hemiparesis.[]

  • Arteriovenous Fistula

    On admission, she was comatose with anisocoria.[] A young child presenting with complaints of tinnitus and mild right hemiparesis was evaluated with an initial magnetic resonance imaging, which revealed a Borden type 2 DAVF[]
