  • Stroke

    Decreased levels of consciousness, hypertension, bradycardia and anisocoria may indicate a pathological rise of intracranial pressure due to cerebral edema.[] Intracranial hemorrhage or microbleeds and leukoaraiosis have an overlap in biology.[] We report on a patient who developed allocentric neglect due to injury of the inferior fronto-occipital fasciculus (IFOF) following intracranial hemorrhage, diagnosed using[]

  • Subdural Hematoma

    The period from losing consciousness to brain herniation presenting as anisocoria was very short-only 30 minutes in our patient.[] Imatinib is believed to cause platelet dysfunction (missed by standard testing), leading to intracranial hemorrhage.[] There are often signs of brainstem compression: miosis, mydriasis, nystagmus, anisocoria, flaccid or hypertonic limbs, and eye deviation.[]

  • Intracranial Hemorrhage

    Initial emergency room evaluation found the patient to have anisocoria with a fixed and dilated right pupil and demonstrated evidence of decorticate posturing.[] "Four Types of Acute Post-Traumatic Intracranial Hemorrhage" The New England Journal of Medicine[] There were 4 hours after patient back to neurosurgical intensive care unit (NICU), patient appeared anisocoria (R/L:4.0/2.5 mm), bilateral light reflexes disappeared, then[]

  • 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[] Twelve patients presented with intracranial hemorrhage and one with headache.[] Brain arteriovenous malformation (BAVM) is a congenital cerebral vascular disease that characterized with intracranial hemorrhage and epilepsy.[]

  • Fibrinolysis

    In Patient 2, intraventricular subsequent bleeding was noted 4 hours after the second 4-mg dose of rt-PA, clinically apparent as anisocoria.[] There were no cases of intracranial hemorrhage.[] These modest benefits come at a 10-fold increase in intracranial hemorrhage (ICH) and a 5-fold increase in major bleeding .[]

  • Cavernous Sinus Thrombosis

    To describe a case of ophthalmic artery occlusion associated with anisocoria and revealing a cavernous sinus thrombosis due to sinusitis.[] Anticoagulant therapy was administered to treat the cavernous sinus thrombosis, but provoked severe intracranial hemorrhage, severely disabling the patient.[] Patients with cavernous sinus thrombosis may also have anisocoria or mydriasis (3rd cranial nerve dysfunction), papilledema, and vision loss.[]

  • Arteriovenous Fistula

    On admission, she was comatose with anisocoria.[] We report a case of tentorial dural arteriovenous fistula (DAVF) with a severe intracranial hemorrhage occurring after Onyx embolization.[] hemorrhage.[]
