BACKGROUND: Transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis (HaNDL) is benign and self-limited, with neurologic deficits including sensory disturbance of one body side, aphasia, nausea/vomiting, weakness, decreased vision, homonymous hemianopsia, photophobia. Acute confusional state can rarely occur. Papilledema and intracranial hypertension have also been described. It is a rare entity mainly affecting adults; however, it has been sporadically described in children and adolescents...

Unruptured cerebral aneurysms sometimes present with visual symptomsdue to compression of the visual pathways. However, until now, unruptured anterior communicating artery (ACoA) aneurysms presenting visual field defects have been extremely rare. The authors report the case of a 51-year-old woman who presented with left homonymous hemianopsia. Radiological findings demonstrated an ACoA aneurysm filled with thrombus, that was compressing the optic chiasm and post-chiasmal tract. The patient underwent clipping of the aneurysm, which resolved the visual field defect...

Background and importance Traditionally, it has been believed that the plexal segment of the anterior choroidal artery (AChoA) can be sacrificed safely. Here, we present a case of choroid plexus arteriovenous malformation (AVM) in which the capsulothalamic artery originated from distal plexal segment of the AChoA. Clinical presentation A 45-year-old man was diagnosed with arteriovenous malformation involving the left inferior horn in screening MRI. Preceding stereotactic radiosurgery, transarterial target embolization was performed...

The radiological spectrum of neuromyelitis optica has become broader since the detection of aquaporin4 antibodies. We report a case of neuromyelitis optica patient with pseudotumoral encephalic lesion. A 66 year-old woman presented with sudden left lateral homonymous hemianopsia. A brain MRI showed an isolated and extensive right temporo-parieto-occipital lesion, involving periventricular white matter and the corpus callosum, with strong enhancement on post-gadolinium T1 weighted images, highly suggestive of lymphoma...

RATIONALE: Functional visual loss (FVL) can manifest as various symptoms. Decreased distant visual acuity is the most common symptom and visual field defect is the second most common symptom. Hemianopsia is rarely reported. In an atypical situation of FVL, it is important to prove that no organic pathology exists, through detailed history taking and appropriate examinations. PATIENT CONCERNS: This review presents the case of a 48-year-old male patient presented with decreased bilateral visual acuity and visual field defect after a traffic accident 3 weeks ago...

AIM: To establish the possibility of retrograde trans-synaptic neural degeneration following acquired post-geniculate visual pathway damage. MATERIAL AND METHODS: Twenty-two patients with homonymous hemianopia caused by acquired post-geniculate visual pathway damage were examined. Peripapillary retinal nerve fiber layer (RNFL) thickness and ganglion cell complex (GCC) measurements were assessed with RTVue-100 Fourier-domain optical coherence tomography (OCT). RESULTS: In 12 out of 22 patients we detected binocular GCC thinning that was ipsilateral to post-geniculate involvement...

BACKGROUND: Laser interstitial thermal therapy (LITT) is quickly emerging as an effective surgical therapy for temporal lobe epilepsy (TLE). One of the most frequent complications of the procedure is postoperative visual field cuts, but the physiopathology of these deficits is unknown. OBJECTIVE: To evaluate potential causes of visual deficits after LITT for TLE in an attempt to minimize this complication. METHODS: This retrospective chart review compares the case of a 24-year-old male who developed homonymous hemianopsia following LITT for TLE to 17 prior patients who underwent the procedure and suffered no visual deficit...

Acute arterial tumor embolism is a rare complication in cancer patients. Most of the previously reported cases of arterial tumor embolism have been associated with pulmonary malignancies and occurred during the intraoperative and postoperative periods. Very few cases occurred spontaneously. To our knowledge, there is no previous report of spontaneous and massive tumor embolism occluding the abdominal aorta in patients suffering from primary pulmonary carcinoma. We describe the case of 64-year-old man who presented with left homonymous hemianopsia and backache...

A 63-year-old woman presented to her ophthalmologist complaining of reading difficulties for two years. Ophthalmological examination revealed a homonymous hemianopsia. Brain magnetic resonance imaging (MRI) scan was interpreted as normal, but positron emission tomography (PET) showed areas of posterior brain hypometabolism. This case highlights the high diagnostic suspicion that ophthalmologists should have regarding posterior cortical atrophy (including the visual variant of Alzheimer disease) in patients complaining of reading difficulties in the setting of a normal ophthalmic examination...

A middle-aged man with a history of type 2 diabetes mellitus, hypertension, hyperlipidemia, prior cerebral vascular accident, and remote history of generalized seizure disorder presented with worsening right-sided visual deficits and focal seizures. On examination the patient had dense homonymous hemianopsia on the right side. He was initially diagnosed with a stroke and underwent further investigation for potential causes. However, upon further review, magnetic resonance imaging (MRI) findings and repeat examination were more consistent with seizure-related effects on cortical brain matter as the cause of his visual disturbances rather than stroke...

Fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory arterial disease that most commonly affects the renal and internal carotid arteries, but intracranial FMD is very rare. We report a patient with FMD involving the posterior cerebral arteries (PCAs). A 24year old female was presented with a 4day history of right homonymous hemianopsia with throbbing headache in the left temporo-occipital area. The brain magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the left PCA territory, while the Time of Flight (TOF) magnetic resonance angiogram (MRA) showed segmental luminal irregularities in the left proximal PCA...

Creutzfeldt-Jakob disease (CJD) is a rare neurodegenerative disorder characterized by rapidly progressing dementia, general neurologic deterioration, and death. When the leading symptoms are visual disturbances, it is termed as the Heidenhain variant of CJD (HvCJD). CJD was reported following prion-contaminated pericardium transplants but never after bovine bioprosthetic cardiac valve. In this case report, we describe HvCJD in a patient who had a bovine bioprosthetic cardiac valve implant. An 82-year-old-woman was referred to neuro-ophthalmology clinic for unexplained visual loss that started 1 month previously...

Homonymous hemianopsia (HH) is a common adverse outcome after stroke. Spontaneous improvement more than 6 months poststroke is thought to be unlikely, and traditional visual rehabilitation techniques lack clear evidence of efficacy. The case presented is of a 22-year-old woman who demonstrated improved compensation of her stroke-induced HH after the initiation of a selective serotonin reuptake inhibitor (SSRI). There is evidence supporting the use of SSRIs to improve poststroke cognitive impairment, motor impairment, and depression...

A 19-year-old woman had a thunderclap headache, followed by left hemiparesis and left homonymous hemianopsia. Laboratory tests showed no signs of infection and immunological test results were unremarkable. MRI revealed a cerebral infarction in the right posterior cerebral artery territory, and digital subtraction angiography(DSA)showed right posterior cerebral artery stenosis on day 2. The first follow-up DSA demonstrated an irregular, bead-like appearance on day 9, but the stenotic lesion returned to normal on day 21...

We report a case of a 55-year-old man who developed acute-onset narrowing of his visual field. He showed right homonymous hemianopsia without any other neurological symptoms and signs. Brain CT and MRI showed localized hemorrhage (about 1.6 ml) in the left lateral geniculate body (LGB). A cerebral angiography showed no vascular anomalies of cerebral vessels, and the left anterior choroidal artery and left lateral posterior choroidal artery could be visualized well. He had hypertension, polycythemia and dyslipidemia and was a habitual smoker and an alcoholic...
