This case presents a departure from the presentation of a traditional posterior circulation cerebral infarction most likely as a result of a rare vascular anomaly rooted in an aberrant embryological process. [karger.com]

The most common presenting symptom of PCA dissection is occipital headache. [ruralneuropractice.com]

A case of bilateral PCA infarct presenting with marked behavioral symptoms and minimal neurological symptoms is presented here. [ijpm.info]

Each patient presented with subarachnoid hemorrhage (SAH), and some of them also presented with intraventricular hemorrhage (IVH) (n = 4) or intracerebral hematoma (ICH) (n = 2). [thejns.org]

Amnesia is usually said to require bilateral lesions but four cases in the present series appeared to have unilateral (left‐sided) occlusion. [onlinelibrary.wiley.com]

• Hemianopsia

  Abstract The authors report a case of isolated homonymous hemianopsia secondary to embolic occlusion of the posterior cerebral artery. The cause of embolism was demonstrated to be spondylitic vertebral artery compression. [ncbi.nlm.nih.gov]

  Right PCA Left homonymous hemianopsia due to damage to right visual cortex in the occipital lobe. [neuroanatomy.ca]

  Whereas a pituitary tumor compressing the optic chiasm results in bilateral temporal heteronymous hemianopsia (where heteronymous means in two different visual fields). [forums.studentdoctor.net]

  Conclusion: Korean medicine treatment can be considered an effective treatment for homonymous hemianopsia in stroke patients. Keywords case report;homonymous hemianopsia;Bojungikki-tang;visual field test;visual defect [koreascience.or.kr]

  She demonstrated a right homonymous hemianopsia but other cranial nerves were normal as was her muscular strength and sensory systems. [lksom.temple.edu]

• Micropsia

  Palinopsia, micropsia, and macropsia These are illusory phenomena that are of uncertain pathophysiology. Palinopsia describes the persistence of a visual image for several seconds to days in a partially blind hemifield. [emedicine.medscape.com]

• Slow Speech

  Stroke affecting the posterior cerebral artery may also affect the brainstem or cerebellum resulting in slurred and slow speech. [newhealthadvisor.com]

Conclusion The symptomatology of the patient did not align with all of the deficits that usually present with an infarction of the posterior circulation, and the radiological workup revealed an fPCA on the right side. [karger.com]

Additional tests can be ordered such as ANA with titers, ESR, CRP, ANCA for vasculitis, hypercoagulable panel for coagulopathy, and genetics tests for an unknown cause of stroke after the first workup. [ncbi.nlm.nih.gov]

Endovascular treatment techniques provide additional treatment options. In selected cases, high revascularization rates following microsurgical thromboembolectomy in the anterior circulation were reported. [ncbi.nlm.nih.gov]

The benefit of mechanical thrombectomy (MT) compared to IV thrombolysis (tPA) for the treatment of an acute posterior cerebral artery (PCA) occlusion is uncertain. [journals.heart.org]

Conclusion : Carotid artery invasion by malignancy portends a poor prognosis. Carotid artery resection can provide reasonable palliation. The head and neck surgeon faces a d i fficult dilemma because of its high mortality and neurologic morbidity. [dbpia.co.kr]

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

Etiologies: Most often embolic from heart, aorta or the internal carotid artery. Rarely, due to intrinsic atherosclerotic disease of the ACA. [casemed.case.edu]

The clinical evidence for herniation itself includes an ipsilateral dilated pupil and contralateral hemiparesis, though these may be difficult to discern in the setting of already increased intracranial pressure due to the underlying etiology. [neuroradiologyonthenet.blogspot.com]

We presented a patient with a posterior cerebral artery territory infarction due to an unexpected etiology as stenosis of internal carotid artery (ICA) with existence of fetal type PCA. 1. [hindawi.com]

The suddenness of the loss suggests a vascular etiology and the symptoms are referable to branches of the posterior cerebral artery. [lksom.temple.edu]

Epidemiology A relatively uncommon form of stroke. However: Stroke is the fourth[2]biggest cause of death in the UK. 25% of lesions causing stroke occur in the vertebrobasilar circulation[1]. [patient.info]

General epidemiological characteristics and clinical presentation are reported in Table 1. Table 1. Characteristics of stroke and stroke mimic population. [scielo.br]

However, there are no epidemiological P2 segment and distal aneurysm data so far. The literature regarding the therapy of P2 segment and distal aneurysms are extremely limited to small case series and case reports. [thejns.org]
