Possible conditions causing high intracranial pressure and papilledema include intracerebral mass lesions, cerebral hemorrhage, head trauma, meningitis, hydrocephalus, spinal cord lesions, impairment of cerebral sinus drainage, anomalies of the cranium, and idiopathic intracranial hypertension (IIH. Irrespective of the cause, visual loss is the feared morbidity of papilledema, and the main mechanism of optic nerve damage is intraneuronal ischemia secondary to axoplasmic flow stasis. Treatment is directed at correcting the underlying cause. In cases where there is no other identifiable cause for intracranial hypertension (ie, IIH the available options include both medical and surgical modalities. Weight loss and diuretics remain the mainstays for treatment of IIH, and surgery is typically reserved for patients who fail, are intolerant to, or non-compliant with maximum medical therapy.

    Full Text Available In the majority of patients with raised intracranial pressure, the papilledema is bilateral. Unilateral papilledema is rare in conditions causing intracranial hypertension, and it has been described in Foster–Kennedy syndrome and in some cases of idiopathic intracranial hypertension. It has never been reported in cerebral venous thrombosis. We report a young lady presenting with features of subacute onset of headache with seizures, on evaluation she had superior sagittal and bilateral lateral sinus thrombosis. The risk factors found on evaluation were Vitamin B12 deficiency and hyperhomocysteinemia. On optic fundus examination, she had swollen optic disc on the right side with normal fundus on the left side, confirmed with the orbital ultrasound B-scan and optic coherence tomography. Her magnetic resonance imaging showed features of raised intracranial pressure with thrombosis of the superior sagittal and bilateral lateral sinus thrombosis. She was treated with anticoagulation (heparin followed by oral anticoagulants, antiedema measures, and vitamin supplementation for hyperhomocysteinemia. She improved over time and was asymptomatic during follow-up. We discuss the possible mechanisms described in the literature for unilateral papilledema. This report highlights the need for carefully performing bilateral fundus examination so as not to miss the vision or life-threatening causes of a headache.

    OBJECTIVE The aim of this study was to report the incidence of and the factors associated with papilledema in children with hydrocephalus. METHODS Patients younger than 15 years of age who had been diagnosed with hydrocephalus and treated by extra-ventricular drainage or ventriculoperitoneal shunt surgery between 2005 and 2015 were retrospectively reviewed. Factors including patient age and sex, etiology of hydrocephalus, duration of signs or symptoms, intracranial pressure (ICP), and presence of papilledema were evaluated. RESULTS Forty-six patients, whose mean age was 6.3 ± 4.7 years, were included in the study. The 19 patients without papilledema had a mean age of 2.7 ± 2.7 years, and the 27 patients with papilledema had a mean age of 8.8 ± 4.2 years (p hydrocephalus were tumor (59%), congenital anomaly (19%), hemorrhage (13%), and infection (9%). CONCLUSIONS Papilledema was more common in patients who were older, who had higher ICP, and whose hydrocephalus had been induced by brain tumor. However, since papilledema was absent in 41% of the children with hydrocephalus, papilledema's absence does not ensure the absence of hydrocephalus, especially in younger patients.

  4. Hard Retinal exudates and visual loss due to papilledema

    Bilateral papilledema developed in a patient with a cystic, grade 3 astrocytoma of the right frontal lobe. Despite successful neurosurgical treatment, 60 Co radiotherapy, and oral corticosteroid therapy, progressive visual loss occurred. At examination one year later, visual activity was 20/200 and 20/70, and extensive lipid exudates in the peripapillary retina and central macula of each eye were noted. Retinal lipid exudates rarely complicate the course of surviving patients who had papilledema from intracranial tumor; physicians involved in the multispecialty care of such patients should be aware of the possible ocular residuals of persistent papilledema in an otherwise successfully treated patient

    To derive a computerized measurement of optic disc volume from digital stereoscopic fundus photographs for the purpose of diagnosing and managing papilledema. Twenty-nine pairs of stereoscopic fundus photographs and optic nerve head (ONH) centered spectral domain optical coherence tomography (SD-OCT) scans were obtained at the same visit in 15 patients with papilledema. Some patients were imaged at multiple visits in order to assess their changes. Three-dimensional shape of the ONH was estimated from stereo fundus photographs using an automated multi-scale stereo correspondence algorithm. We assessed the correlation of the stereo volume measurements with the SD-OCT volume measurements quantitatively, in terms of volume of retinal surface elevation above a reference plane and also to expert grading of papilledema from digital fundus photographs using the Frisén grading scale. The volumetric measurements of retinal surface elevation estimated from stereo fundus photographs and OCT scans were positively correlated (correlation coefficient r(2) = 0.60; P photographs compares favorably with that from OCT scans and with expert grading of papilledema severity. Stereoscopic color imaging of the ONH combined with a method of automated shape reconstruction is a low-cost alternative to SD-OCT scans that has potential for a more cost-effective diagnosis and management of papilledema in a telemedical setting. An automated three-dimensional image analysis method was validated that quantifies the retinal surface topography with an imaging modality that has lacked prior objective assessment.

    Full Text Available We report on a patient with carboplatin-induced bilateral papilledema, as it was described in the 1970s for cisplatin. Loss of visual accuracy up to full blindness, often loss of color vision and scotomas can be seen as a result of cortical blindness, macula degeneration, retrobulbar neuritis and papilledema. These symptoms are mostly unilateral and initially mild, so that more chemotherapy is given before the diagnosis is made. The symptoms are usually reversible within weeks to months after cessation of the platinum treatment. The therapeutic strategy is stopping the platinum treatment. In addition the empiric use of corticosteroids is suggested.

    Full Text Available A 45-year-old male patient presented with gradual onset of headache, vomiting and blurring of vision of 28 days duration. Ophthalmological examination revealed normal anterior segment and pupillary reflex. No abnormality was detected in the vitreous. Optic disc showed features of advanced papilledema with normal macula and retinal periphery in both eyes. Visual acuity was 20/200 in the right eye and counting fingers close range in the left eye. Non-contrast computed tomography of brain was normal and magnetic resonance imaging showed sagittal sinus thrombosis without any evidence of venous infarction or intracranial mass. Routine hematological investigations revealed increased hemoglobin level, packed cell volume and leucocytosis. Further investigation revealed increased Vitamin B12 and decreased serum erythropoietin. A diagnosis of polycythemia vera was made from the above findings. This case is being presented for the rarity of association of polycythemia vera with bilateral advanced papilledema due to sagittal sinus thrombosis.

    Full Text Available Purpose: Introduction to the ophthalmic literature of an unusual cause of papilledema and subsequent optic atrophy: X-linked hypophosphatemic rickets (XLH. Methods: Case report of a 3-year-old female presenting with papilledema resulting from craniosynostosis secondary to XLH. Results: Early intervention with craniofacial surgery prevented the development of optic atrophy. Conclusion: Children with XLH should be screened for ophthalmic evidence of elevated intracranial pressure to aid early intervention and prevention of permanent loss of vision.

    Purpose. Geometric morphometrics (GM) was used to analyze the shape of the peripapillary retinal pigment epithelium–Bruch's membrane (RPE/BM) layer imaged on the SD-OCT 5-line raster in normal subjects and in patients with papilledema and ischemic optic neuropathy. Methods. Three groups of subjects were compared: 30 normals, 20 with anterior ischemic optic neuropathy (AION), and 25 with papilledema and intracranial hypertension. Twenty equidistant semilandmarks were digitized on OCT images of the RPE/BM layer spanning 2500 μm on each side of the neural canal opening (NCO). The data were analyzed using standard GM techniques, including a generalized least-squares Procrustes superimposition, principal component analysis, thin-plate spline (to visualize deformations), and permutation statistical analysis to evaluate differences in shape variables. Results. The RPE/BM layer in normals and AION have a characteristic V shape pointing away from the vitreous; the RPE/BM layer in papilledema has an inverted U shape, skewed nasally inward toward the vitreous. The differences were statistically significant. There was no significant difference in shapes between normals and AION. Pre- and posttreatment OCTs, in select cases of papilledema, showed that the inverted U-shaped RPE/BM moved posteriorly into a normal V shape as the papilledema resolved with weight loss or shunting. Conclusions. The shape difference in papilledema, absent in AION, cannot be explained by disc edema alone. The difference is a consequence of both the translaminar pressure gradient and the material properties of the peripapillary sclera. GM offers a novel way of statistically assessing shape differences of the peripapillary optic nerve head. PMID:21896851

    A 46 year old patient presented with visual loss in the left eye during the previous months. Ophthalmoscopic examination and magnetic resonance angiography found the presence of papilledema due to thrombosis in superior sagittal sinus. The examination findings revealed a mantle cell lymphoma. Cerebral venous thrombosis is an unusual cause of papilledema. This type of thrombosis may be secondary to hyper-viscosity within a context of a paraneoplastic syndrome. Copyright © 2015 Sociedad Española de Oftalmología. Published by Elsevier España, S.L.U.

    The case is presented of a 29-year-old woman who complained of headache over a period of several days, with loss of visual acuity and pain in her left eye. She had a 3-year history of type 1 diabetes mellitus, and was an immigrant from Ecuador. The funduscopic examination revealed a papilledema. The polymerase chain reaction (PCR) study of the cerebrospinal fluid was positive for Mycobacterium tuberculosis (MTB). She showed a marked improvement after treatment with anti-TB drugs. About a third of the world's population has a latent infection of MTB, comorbidity between diabetes mellitus and tuberculosis has been reported, particularly in undeveloped countries.

    Full Text Available Chronic headaches, associated with papilledema and pulsatile tinnitus without any neuroradiologic, cytobiochemical or cerebrospinal fluid abnormalities are suggestive of idiopathic intracranial hypertension (IIH. However the absence of the papilledema does not rule out this diagnosis. The reason why some patients do not develop papilledema in IIH is ignored, however there are some hypotheses concerning the structure of the optical nerve. In this study we described two female patients that presented diagnosis of IIH with papilledema, with subsequent resolution of papilledema without the due resolution of intracranial hypertension. The long-term behavior of the optic nerve (ON facing an increased intracranial pressure was evaluated through repeated measurements of the intracranial pressure. We concluded that the ON submitted to high intracranial pressure for a certain lenght of time can adapt itself with subsequent disappearance of the papilledema. The presence or not of papilledema in IIH can be related to the period in which the diagnosis is accomplished.Cefaléias com características crônica, diária, acompanhadas de edema de papila e tinitus pulsátil, sem nenhum achado neuroradiológico ou citobioquímico no líquor, são altamente sugestivas de hipertensão intracraniana idiopática (HII. Entretanto a ausência do papiledema não invalida o seu diagnóstico. A razão pela qual alguns pacientes não desenvolvem papiledema na HII é desconhecida, porém algumas hipóteses relacionadas com propriedades intrínsecas da bainha do nervo óptico têm sido propostas. Neste estudo relatamos dois pacientes do sexo feminino que apresentaram diagnóstico de HII com papiledema, evoluindo para resolução do papiledema sem a devida resolução da HII. O comportamento do nervo óptico (NO frente ao aumento da pressão intracraniana foi avaliado neste estudo a partir de um monitoramento intermitente criterioso da pressão intracraniana.

    2015-01-01

    We report a diagnostically challenging case of papilloedema in a morbidly obese, 25 year old male who presented to us with blurring of vision of both eyes, but more marked in the right. Fundus examination revealed severe papilloedema, with corresponding visual field and colour vision defects. He was worked up for possible life threatening causes of papilloedema like intracranial space occupying lesion but his CT scan was normal. As his hematocrit was in the polycythemic range, multiple venesections were performed in fear that the hyperviscosity picture could be a contributing factor. However there was no change in symptoms or the fundus appearance. We could not come to a diagnosis of idiopathic intracranial hypertension too because he refused lumbar puncture. A sleep study was done as he did give symptoms of mild obstructive sleep apnea but the results were that of severe disease. He was given therapeutic nocturnal oxygen by CPAP to prevent further cardiovascular and respiratory complications and interestingly enough it helped in treating the papilloedema. He was seen 2 months after commencement of continuous positive airway pressure (CPAP) with good functional and anatomical recovery. (author)

    Three cases of papilledema secondary to chronic excessive vitamin A intake are presented, and the optic disk changes are documented with intravenous fluorescein angiography. Two of the three patients reported in this study were symptomatic with blurred vision and systemic complaints. The symptoms of blurred vision and systemic complaints disappeared within one week, and papilledema resolved over several months after discontinuance of vitamin A. The fluorescein angiographic changes observed in the optic disk of patients with hypervitaminosis A are similar to those associated with other known causes of papilledema. Since vitamin A is a nonprescription drug, and its indiscriminate use is potentially great, any history of vitamin ingestion should be elicited during the evaluation of papilledema.

    Idiopathic intracranial hypertension (IIH) is a clinical condition of increased intracranial pressure (ICP) without an obvious underlying pathological brain lesion. It is usually characterized by headache, neck pain, vomiting, visual disturbances, papilledema, cranial nerve palsy or a combination of these signs and symptoms.

  5. IIH with normal CSF pressures?

    Directory of Open Access Journals (Sweden)

    Soh Youn Suh

    2013-01-01

    Full Text Available Idiopathic intracranial hypertension (IIH is a condition of raised intracranial pressure (ICP in the absence of space occupying lesions. ICP is usually measured by lumbar puncture and a cerebrospinal fluid (CSF pressure above 250 mm H 2 O is one of the diagnostic criteria of IIH. Recently, we have encountered two patients who complained of headaches and exhibited disc swelling without an increased ICP. We prescribed acetazolamide and followed both patients frequently; because of the definite disc swelling with IIH related symptoms. Symptoms and signs resolved in both patients after they started taking acetazolamide. It is generally known that an elevated ICP, as measured by lumbar puncture, is the most important diagnostic sign of IIH. However, these cases caution even when CSF pressure is within the normal range, that suspicion should be raised when a patient has papilledema with related symptoms, since untreated papilledema may cause progressive and irreversible visual loss.

    Altered intracranial pressure (ICP) is involved/implicated in several ocular conditions: papilledema, glaucoma and Visual Impairment and Intracranial Pressure (VIIP) syndrome. The biomechanical effects of altered ICP on optic nerve head (ONH) tissues in these conditions are uncertain but likely important. We have quantified ICP-induced deformations of ONH tissues, using finite element (FE) and probabilistic modeling (Latin Hypercube Simulations (LHS)) to consider a range of tissue properties and relevant pressures.

    Detecting and monitoring optic neuropathy in patients with craniosynostosis is a clinical challenge due to limited cooperation, and subjective measures of visual function. The purpose of this study was to appraise the correlation of peripapillary retinal nerve fiber layer (RNFL) thickness measured by spectral-domain ocular coherence tomography (SD-OCT) with indication of optic neuropathy based on fundus examination. The medical records of all patients with craniosynostosis presenting for ophthalmic evaluation during 2013 were retrospectively reviewed. The following data were abstracted from the record: diagnosis, historical evidence of elevated intracranial pressure, current ophthalmic evaluation and visual field results, and current peripapillary RNFL thickness. A total of 54 patients were included (mean age, 10.6 years [range, 2.4-33.8 years]). Thirteen (24%) had evidence of optic neuropathy based on current fundus examination. Of these, 10 (77%) demonstrated either peripapillary RNFL elevation and papilledema or depression with optic atrophy. Sensitivity for detecting optic atrophy was 88%; for papilledema, 60%; and for either form of optic neuropathy, 77%. Specificity was 94%, 90%, and 83%, respectively. Kappa agreement was substantial for optic atrophy (κ = 0.73) and moderate for papilledema (κ = 0.39) and for either form of optic neuropathy (κ = 0.54). Logistic regression indicated that peripapillary RNFL thickness was predictive of optic neuropathy (P optic neuropathy than visual field testing (likelihood ratio = 10.02; P = 0.002). Sensitivity and specificity of logMAR visual acuity in detecting optic neuropathy were 15% and 95%, respectively. Peripapillary RNFL thickness measured by SD-OCT provides adjunctive evidence for identifying optic neuropathy in patients with craniosynostosis and appears more sensitive at detecting optic atrophy than papilledema.

    2012-02-01

    Full Text Available Idiopathic intracranial hypertension (IIH or benign intracranial hypertension is a neurological syndrome characterized by elevated intracranial pressure. This uncommon disorder occurs primarily in obese women aged 10 to 50 years, sometimes in association with endocrine and metabolic dysfunction, with systemic diseases or when treated with multiple medications. We describe a case of IIH in a 43-year-old woman with schizophrenia treated with risperidone, demonstrating a typical clinical picture of benign intracranial hypertension. For the 5 years of treatment with risperidone she put on 35 kg in total (BMI> 35; for the last 2-3 months she began to complain of visual obscurations, nausea with vomiting. Ophthalmoscopy revealed bilateral asymmetric papilledema (OD>OS. Magnetic resonance imaging was normal, intracranial pressure was elevated IIH was diagnosed. Risperidone was discontinued and replaced with Seroquel 200 mg daily. Treatment with furosemide and mannitol 10 % was initiated. Papilledema resolved completely over the next 2 months. The patient was followed-up for four years after risperidone withdrawal. Weight loss of 28 kg was noted for four years. There were no relapses of headache, nausea, visual obscuration. Ophthalmologic examination revealed no papilledema.We suggest that prolonged use of antipsychotics, such as risperidone, should require proper surveillance for possible development of IIH and routine ophthalmologic examinations should be performed.

    Arnold Chiari malformation type 1 is defined as a herniation of the cerebellar tonsils into the foramen magnum of more than 5 mm. Symptoms are most commonly dominated by occipital headache, torticollis and sometimes swallowing disorders. Ophthalmologically abnormal convergences, oculomotor palsy and diplopia are the main clinical signs. We report the case of a 9 year old child, who presented with visual loss evolving since 6 months. Ophthalmologic examination showed visual acuity of 4/10 in both eyes, retained ocular motility and rotational nystagmus. The examination of the anterior segment of the eye showed megalocornea with no evidence of goniodysgenesis, iridodonesis associated with atrophy of the dilator muscle and microcoria with lazy photomotor reflex. Normal intraocular pressure was 14 mmHg. Ocular fundus examination, despite difficulties in performing it, objectified bilateral papilledema (stage II). General physical examination showed torticollis, scoliosis and a tetra-pyramidal syndrome. MRI showed Chiari malformation type I associated with hydrocephalus and syringomyelia. Neurosurgical intervention based on internal CSF drainage with occipitocervical osteo-dural decompression was proposed. The evolution was favorable with regression of clinical signs. Ophthalmologically, there was a regression of papilledema but visual acuity remained stationary. The occurrence of papilledema associated with Chiari malformation type 1 is rare, it has been only reported in 2% of symptomatic patients. Its pathophysiology is still poorly understood. The originality of our study consists in the association of cerebellar malformations with ocular malformations including megalocornea and microcoria which make ophthalmologic examination more difficult to perform.

    Craniopharyngioma often causes visual loss due to the close relation to the anterior visual pathways. This study investigates the incidence and predictors of visual outcomes in patients with craniopharyngioma. Data from sixty-six patients who underwent surgery for craniopharyngioma from 2009 to 2013 in Denmark were reviewed. Primary outcomes were visual acuity (VA) and visual field (VF) defects from pre-and postoperative visits. Secondary outcomes were optic nerve atrophy (OA) and papilledema. Fifty-eight patients were included. The VA of the patients 1-year after surgery improved by -0.16 log(MAR) (95%CI: -0.30 to -0.02; p = 0.0266). Visual field (VF) defects worsened in 17 eyes (30%), remained stable in 21 eyes (37%) and improved in 19 eyes (33%). The presence of papilledema and the absence of OA were significantly correlated with an improvement in VA postoperatively (p = 0.011 and p = 0.011, respectively). Patients undergoing surgery within a week or less after their first ophthalmological examination had a significant improvement in VA (-0.36; 95%CI: -0.62 to -0.09; p = 0.0099). Patients undergoing surgery using a subfrontal approach also showed improvement in VA (p = 0.048). Tumour recurrence had a significantly worse VA outcome (p = 0.0074). Patients show a slight improvement in VA 1-year after operation for craniopharyngioma. The presence of papilledema and early surgical intervention is associated with a significant improvement in VA. Early involvement of a dedicated ophthalmologist is recommended to secure an early detection of a visual decline and potential tumour recurrence. © 2017 Acta Ophthalmologica Scandinavica Foundation.

    The authors report here a case of hemangioma of the left parietal bone which presented headache and papilledema. This patient is a 37-year-old female who had, prior to admission, complained of increasing headache for one year and blurred vision for three months. She had no history of head injury. Local physical examinations revealed a slight bulging in her left parietal region which was insensitive to palpation and not adherent to the overlying scalp. Neurological examinations revealed bilateral papilledema and an incongruous bitemporal upper quadrant defect in the visual field. All the other neurological and laboratory data were normal. A plain skull roentogenogram showed a 9 x 9 cm osteolytic and characteristic honeycomb lesion in the parietal region. Systemic bone survey revealed a similar lesion in the right tibia which was not histologically examined. A marked accumulation of isotopes was detected on the bone scintigrams at both lesions. Selective external carotid angiograms demonstrated a tumor stain fed by the superficial temporal, occipital, and middle meningial arteries. CT scans of the brain and skull clearly showed a local thickening of and structural changes in the skull bone and also a mass effect on the brain and lateral ventricle. The lesioned bone was removed en bloc and replaced by an artificial bone. It was highly vascular, but not adherent to the overlying dura. The post-operative course was uneventful, and the headache and papilledema disappeared. Hemangioma of the skull presenting marked hyperostosis, as reported above, seems to be rare. In addition, in this case, skeletal angioma without any clinical manifestation was detected. Clinical and radiological pictures of the hemangioma of the skull and other bones were briefly discussed.

    A defect in a phosphate-regulating gene leads to the most common form of rickets: X-linked hypophosphatemic rickets (XLH) or vitamin D-resistant rickets (VDDR). XLH has been associated with craniosynostosis, the sagittal suture being the most commonly involved. We present three patients with rickets and symptomatic sagittal suture craniosynostosis all of whom presented late (>2 years of age). Two had a severe phenotype and papilledema, while the third presented with an osseous bulging near the anterior fontanel and experienced chronic headaches. All underwent successful cranial vault expansion. Rachitic patients with scaphocephaly should be screened for craniosynostosis.

    2013-01-01

    BACKGROUND: Idiopathic intracranial hypertension (IIH) is a condition of raised intracranial pressure (ICP) in the absence of space-occupying lesions or other known etiology. It primarily affects young obese females, and potentially causes permanent visual loss due to papilledema and secondary...... optic atrophy. The aim of this study was to evaluate the diagnostic value of optical coherence tomography (OCT) as a marker for CSF opening pressure in patients with idiopathic intracranial hypertension (IIH). METHODS: We conducted a case-control study of 20 newly diagnosed, 21 long-term IIH patients...

    A 56 year-old male presented blurred vision and diplopia for 2 months, left unilateral exophthalmos, restricted ocular motility and papilledema. The imaging proofs showed osteolytic lesions in the left sphenoid bone, fourth rib and fourth dorsal vertebral body with associated masses of soft tissues. Biopsy was performed and the diagnosis of plasma cell neoplasm was established. The diagnosis of non-secretory multiple myeloma was made by analytical criteria and bone marrow biopsy. Local radiotherapy and polychemotherapy was prescribed. The ophthalmologist can play an important role in the diagnosis of systemic neoplasms that require the intervention of a multidisciplinary team.

    Frank-ter Haar syndrome (FTHS) is an autosomal recessive disorder characterized by abnormalities that affect the development of bone, heart, and eyes. We report a sibling pair with FTHS caused by a homozygous, novel mutation pLys133Glnfs*13 in the SH3PXD2B gene: one sibling had bilateral ocular hypertension and unilateral colobomas of iris, choroid and retina; the other, unilateral myelinated nerve fiber layer of the optic disk and papilledema due to idiopathic intracranial hypertension. Both children had refractive amblyopia and megalocornea. Copyright © 2017 American Association for Pediatric Ophthalmology and Strabismus. Published by Elsevier Inc. All rights reserved.

    Full Text Available The diagnosis and treatment of central retinal vein occlusion was reported in a young patient. Central retinal vein occlusion was probably related to secondary to reactive thrombocytosis after splenectomy. The patient was treated with steroids for papilledema and administered coumadin and aspirin. The symptoms resolved, and the findings returned to normal within three weeks. Current paper emphasizes that, besides other well-known thrombotic events, reactive thrombocytosis after splenectomy may cause central retinal vein occlusion, which may be the principal symptom of this risky complication. Thus, it can be concluded that followup for thrombocytosis and antithrombotic treatment, when necessary, are essential for these cases.

    A 31-year old Filipino male presented with bifrontal throbbing headache and blurring of vision of 2 weeks duration. He was initially seen by an internist who considered a space occupying lesion based on the signs and symptoms and on his funduscopic findings of beginning papilledema. CT scan ruled out the presence of a tumor and he was then referred to the Opthamology Department. Ocular findings revealed bilateral panuveitis with retinal detachment of the left eye. A diagnosis of Vogt-Koyanagi-Harada syndrome was made and therapy with high dose systemic prednisolone was instituted which resulted in rapid improvement and the attainment of a good visual activity.

Association of rituximabwith this condition was suspected as there was norecurrence of PRES after receiving two more cycles of CHOPwithout rituximab. Contrary to previously published casereports, this patient had a delayed clinical presentation.

  1. Anterior ischemic optic neuropathy in association with optic nervehead drusen

    Full Text Available Optic nerve head drusen (ONHD are incidental ophthalmologic finding in the optic nerve. Patients with ONHD are often asymptomatic, but sometimes present with transient visual obscuration′s (TVO, the reported incidence of which is 8.6%. Optic nerve head drusen are of two types: Superficial; visible and deep. The deep-buried drusen mimic papilledema. Because of the varied presentation deep-buried drusen pose a diagnostic challenge to the ophthalmologists. In young patients, they are mistaken for papilledema as it is clinically difficult to detect a buried drusen in the optic nerve head, but are seen on the surface with aging as the retinal nerve fiber layer thins out. They are observed as pale yellow lesions more often located towards the poles. Clinical examination aided with diagnostic tests like computed tomography (CT orbits and ultrasound B scan can help establish the diagnosis. Herein, we report a rare case of optic nerve head drusen in a young lady, who presented with loss of vision and clinical evaluation and investigations suggested ONHD with anterior ischemic optic neuropathy.

Inclusion criteria were papilledema, normal brain computer tomography or magnetic resonance imaging, cerebrospinal fluid pressure greater than 250 mm H2O, normal cerebrospinal fluid content, and a nonfocal neurologic examination except for sixth nerve palsy.Results: Of the nine patients, eight were girls. Five girls were overweight and one boy was obese. The most common presenting symptom was headache (5 patients. Diplopia or strabismus did not occur in our group. Visual field abnormalities were present in all eyes, and severe visual loss resulting in light perception vision occurred in both eyes of one patient. Eight patients were treated medically with acetazolamide alone, and one girl needed a combination of acetazolamide and corticosteroids. This girl also required optic nerve sheath decompression surgery. Resolution of papilledema and recovery of visual function occurred in all patients.Conclusions: Idiopathic intracranial hypertension in prepubertal children is rather uncommon. Prompt diagnosis and management are important to prevent permanent visual loss.Keywords: idiopathic intracranial hypertension, pediatric, treatment

    The authors experienced a case of spontaneous ventriculocisternostomy diagnosed by CT scan with metrizamide and Conray. Patient was 23-year-old male who had been in good health until one month before admission, when he began to have headache and tinnitus. He noticed bilateral visual acuity was decreased about one week before admission and vomiting appeared two days before admission. He was admitted to our hospital because of bilateral papilledema and remarkable hydrocephalus diagnosed by CT scan. On admission, no abnormal neurological signs except for bilateral papilledema were noted. Immediately, right ventricular drainage was performed. Pressure of the ventricle was over 300mmH 2 O and CSF was clear. PVG and PEG disclosed an another cavity behind the third ventricle, which was communicated with the third ventricle, and occlusion of aqueduct of Sylvius. Metrizamide CT scan and Conray CT scan showed a communication between this cavity and quadrigeminal and supracerebellar cisterns. On these neuroradiological findings, the diagnosis of obstructive hydrocephalus due to benign aqueduct stenosis accompanied with spontaneous ventriculocisternostomy was obtained. Spontaneous ventriculocisternostomy was noticed to produce arrest of hydrocephalus, but with our case, spontaneous regression of such symptoms did not appeared. By surgical ventriculocisternostomy (method by Torkildsen, Dandy, or Scarff), arrest of hydrocephalus was seen in about 50 to 70 per cent, which was the same results as those of spontaneous ventriculocisternostomy. It is concluded that VP shunt or VA shunt is thought to be better treatment of obstructive hydrocephalus than the various kinds of surgical ventriculocisternostomy. (J.P.N.)

    This retrospective chart review was conducted to determine the presenting signs and symptoms of patients with primary brain tumors diagnosed in the emergency department. There were 101 patients (65 males and 36 females) identified with a hospital discharge diagnosis of primary brain tumor who were admitted through the emergency department. The presenting symptoms included headache (56 patients), altered mental status (51 patients), ataxia (41 patients), nausea or vomiting (37 patients), weakness (27 patients), speech deficits (21 patients), and sensory abnormalities (18 patients). The presenting signs included motor weakness (37 patients), ataxia (37 patients), papilledema (28 patients), cranial nerve palsies (26 patients), visual deficits (20 patients), and speech deficits (12 patients). The average age was 42.8 years, with a range of 3 days to 88 years. The majority of tumors were malignant astrocytomas. Tumor location was cortical in 68 patients, subcortical in 9 patients, and brainstem or cerebellum in 24 patients. In conclusion, patients of all ages may present to the emergency department with a variety of symptoms resulting from a primary brain tumor. Headache and altered mental status were common in our series of patients, but symptoms will depend on the size, location, and type of tumor. A complete neurologic examination is essential, including evaluation for papilledema.

    Full Text Available Pseudotumor cerebral (PC é uma síndrome, caracterizada pela presença de hipertensão intracraniana (HIC e sistema ventricular normal. Pacientes submetidos a transplante renal parecem ser mais suscetíveis a desenvolvê-la, devido à terapia com imunossupressores. Ciclosporina (CsA é uma causa rara de PC, pouco descrita na literatura e que deve ser lembrada no diagnóstico diferencial de HIC e papiledema nesses pacientes. Relatamos um caso de um menino de 10 anos, há três anos com enxerto renal, em uso crônico de micofenolato mofetil (MMF, CsA e baixas doses de prednisona que apresentou quadro de cefaleia, vômitos, diplopia e fotofobia. Fundoscopia revelou edema de papila bilateral. Exame do líquor (LCR e de imagem foram normais. Após exclusão de causas secundárias, foi feito diagnóstico de PC devido ao uso crônico de CsA, que, portanto, foi substituída por Sirolimus. O paciente apresentou melhora clínica progressiva, com resolução do papiledema após três mesesPseudotumor cerebri (PC is a syndrome characterized by the presence of intracranial hypertension (ICH and no alteration in the ventricular system. Renal transplanted patients seem more susceptible to develop it due to immunosuppressive therapy. Cyclosporin (CsA is a rare cause of PC, scarcely reported in the literature, and should be considered in the differential diagnosis of ICH and papilledema in those patients. We report the case of a 10-year-old boy, with a renal allograft for three years, on chronic use of mycophenolate mophetil (MMF, CsA, and low doses of prednisone. The patient presented with headache, vomiting, diplopia, and photophobia. Funduscopy showed bilateral papilledema. Cerebrospinal fluid analysis and imaging tests were normal. After excluding secondary causes, PC was diagnosed based on the chronic use of CsA, which was then replaced by sirolimus. After that, the patient progressively improved, and the papilledema resolved in three months

    Full Text Available The retinopathy in association with malaria fever described so far includes retinal hemorrhages, vessel changes, retinal discoloration/whitening and papilledema. Malaria retinopathy has been mostly described in severe cases, associated with Plasmodium falciparum, correlating the patho-physiology of retinal and cerebral manifestations. We report an unusual case of proliferative retinopathy as a manifestation of malaria fever, caused by P. falciparum with no cerebral involvement. The patient had features of unilateral retinal vascular occlusion with proliferative changes and vitreous hemorrhage. To the best of our knowledge, such a case has never been reported so far in the literature. This report highlights the possible occurrence of severe proliferative changes associated with malaria fever, which if diagnosed early can prevent possible blindness.

    Primary central nervous system lymphomas (PCNSL) are rare neoplasms. AIM. To study the clinical aspects and the immuno-phenotype of all cases of PCNSL in a 20 years lapse in a referral hospital in Northeastern Mexico. From January 1986 to December 2005 all PCNSL histologically confirmed were studied. The primary lymphomas were 1% of malignant central nervous system neoplasms. 21 cases were studied (ages from 9-70 years) with male predominance (2:1). 24% patients had immuno-suppression. The more frequent clinical data were: papilledema (71%), headache (62%), paresis (48%) and seizures (33%). 33% of patients died during the first six months after diagnosis. The T lymphomas were 19% of cases and corresponded to small cell type. PCNSL are still a diagnostic challenge. Multicenter studies are required in order to determine the best treatment protocol.

    1966-01-01

    Benign intracranial hypertension (pseudotumor cerebri), a syndrome common to a number of disorders, is characterized by headaches and blurred vision. The patient is alert and has papilledema without localizing signs. Air studies show normal ventricles under increased pressure. The authors describe 61 consecutive cases of this pseudotumour, 48 of which were in fat young women, and propose that this group represents a clinical entity that has hitherto received little attention. In these 61 patients, 40 complete-exchange pneumoencephalograms showed normal ventricles, normal fluid volume and prominent cortical sulci. In 32, subtemporal decompression resulted in prompt and lasting relief. Three patients had late convulsive seizures after surgery. Seven patients had nasal quadrantanopsias, the implications of which are discussed. The authors believe that the high intracranial pressure in this condition is due to cerebral hyperemia, not brain edema. Further investigation will perhaps demonstrate a relationship between obesity, vascular dilatation and increased intracranial pressure. ImagesFig. 1 PMID:5296376

She was diagnosed as idiopathic intracranial hypertension (IIH. IIH can present with both papilledema and dural ectasia although the latter is usually seen as an isolated entity. Various conditions also have been implicated in IIH. However, apart from female sex, recent weight gain and obesity, there are no proven associations. In this case report, we present a case of IHH associated with two different pathologies: dural ectasia of the optic nerve sheaths and monocular proptosis. (Turk J Ophthalmol 2013; 43: 297-300

    2005-01-01

    Full Text Available We report about two young girls who developed progressive visual failure secondary to increased intracranial pressure and had significant proximal muscle weakness of limbs. Patients with elevated intracranial pressure (ICP may present with "false localizing signs", besides having headache, vomiting and papilledema. Radicular pain as a manifestation of raised ICP is rare and motor weakness attributable to polyradiculopathy is exceptional. Two patients with increased intracranial pressure without lateralizing signs′ had singnificant muscle weakness. Clinical evaluation and laboratory tests did not disclose any other cause for weakness. Following theco-peritoneal shunt, in both patients, there was variable recovery of vision but the proximal weakness and symptoms of elevated ICP improved rapidly. Recognition of this uncommon manifestation of raised ICP may obviate the need for unnecessary investigation and reduce morbidity due to weakness by CSF diversion procedure.

    Idiopathic intracranial hypertension (IIH) results in raised intracranial pressure (ICP) leading to papilledema, visual dysfunction, and headaches. Obese females of reproductive age are predominantly affected, but the underlying pathological mechanisms behind IIH remain unknown. This review provides an overview of pathogenic factors that could result in IIH with particular focus on hormones and the impact of obesity, including its role in neuroendocrine signaling and driving inflammation. Despite occurring almost exclusively in obese women, there have been a few studies evaluating the mechanisms by which hormones and adipokines exert their effects on ICP regulation in IIH. Research involving 11β-hydroxysteroid dehydrogenase type 1, a modulator of glucocorticoids, suggests a potential role in IIH. Improved understanding of the complex interplay between adipose signaling factors such as adipokines, steroid hormones, and ICP regulation may be key to the understanding and future management of IIH.

    2016-04-01

    Full Text Available Gorham-Stout disease (GSD, also known as vanishing bone disease, is a rare disorder, which most commonly presents in children and young adults and is characterized by an excessive proliferation of lymphangiomatous tissue within the bones. This lymphangiomatous proliferation often affects the cranium and, due to the proximate location to the dura surrounding cerebrospinal fluid (CSF spaces, can result in CSF leaks manifesting as intracranial hypotension with clinical symptoms to include orthostatic headache, nausea, and vertigo. We present the case of a boy with GSD and a known history of migraine headaches who presented with persistent headaches due to increased intracranial pressure. Although migraine had initially been suspected, he was eventually diagnosed with intracranial hypertension after developing ophthalmoplegia and papilledema. We describe the first known instance of successful medical treatment of increased intracranial pressure in a patient with GSD.

    Full Text Available Abstract Background Cerebral venous sinus thrombosis is an infrequent disease with a variety of causes. Pregnancy, puerperium, contraceptive pills and intracranial infections are the most common causes. The patient may present with headache, focal neurological deficits and seizures. The clinical outcome is highly variable and treatment with heparin is advised. Case presentation The patient is a 22 year old male who presented with headache, repeated vomiting and papilledema. He was a bodybuilder doing exercise since 5 years ago, who had used nandrolone decaonoate 25 milligrams intramuscularly during the previous 5 months. Brain MRI and MRV showed superior sagital and transverse sinus thrombosis and extensive investigations did not reveal any known cause. Conclusions We suggested that androgen was the predisposing factor in our patient. Androgens may increase coagulation factors or platelet activity and cause arterial or venous thrombosis. As athletes may hide using androgens it should be considered as a predisposing factor for thrombotic events in such patients.

    Full Text Available Presence of an arachnoid cyst at craniospinal junction is not very common. This is a very rare anatomic site, with only seven other cases reported in the literature. We report a case of large intradural craniospinal arachnoid cyst presenting with obstructive hydrocephalus and cranial nerve palsy. A 39-year-old male presented with 8-month history of neck pain, headache, vomiting, visual disturbances, diminished taste sensation, and numbness of face. He had bilateral papilledema on ophthalmoscopy. Magnetic resonance imaging (MRI revealed a posterior fossa arachnoid cyst extending down to the lower border of C5 vertebra. Posterior decompression was done through C5 laminectomy. He made a full recovery and was asymptomatic at 6-month follow-up examination. The clinical features, diagnosis, and management of these rare craniospinal arachnoid cysts are discussed.

    POEMS syndrome is a rare disorder, also known as Crow-Fukase, PEP or Takatsuki syndrome. The acronym, POEMS, represents polyneuropathy, organomegaly, endocrinopathy, M protein and skin change. However, there are associated features not included in the acronym such as sclerotic bone lesions, Castleman disease, papilledema, thromobocytosis, peripheral edema, ascites, effusion, polycythemia, fatigue and clubbing. In most cases, osseous lesions in POEMS syndrome present as an isolated sclerotic deposit and that reveal as osteosclerotic myeloma. Several cases of {sup 18}F-FDG PET in multiple myeloma involvements were reported, but there was no previous literature that reported FDG PET findings in POEMS syndrome. We describe here a 66-year-old patient with POEMS syndrome who underwent {sup 18}F-FDG PET/CT image.

    A 28 years old female presented with headache, fever, altered sensorium and right side weakness for one week. She was febrile and drowsy with right sided hemiplegia and papilledema. Tuberculous or bacterial meningitis, tuberculoma and abscess were at the top of the diagnosis list followed by Herpes simplex meningo-encephalitis (HSE). MRI showed abnormal signal intensity of left temporal lobe without significant post-contrast enhancement and midline shift. CSF examination was normal, gram stain and Ziehl-Neelsen stain showed no micro-organism, or acid fast bacilli. CSF for MTB PCR was negative. PCR DNA for Herpes simplex 1 on CSF was detected. Acyclovir was started and the patient was discharged after full recovery. A high index of suspicion is required for HSE diagnosis in Pakistan where other infections predominantly affect the brain and HSE may be overlooked as a potential diagnosis. (author)

    Post-mortem intraocular findings in two autopsy cases with traumatic intracranial haemorrhage were obtained using an ophthalmological endoscope. The endoscopy results clearly revealed the presence of intraocular haemorrhages and papilledema caused by intracranial haemorrhage. Post-mortem ophthalmological endoscopy offers several benefits. First, post-mortem intraocular findings can be directly observed in corpses with post-mortem clouding of the cornea. Secondly, the endoscopy only requires a 0.9 mm incision in the sclera and does not require the removal of the eye from the corpse, a procedure that should be avoided for ethical and cosmetic reasons. Thus, post-mortem opthalmological endoscopy is a useful method for obtaining intraocular findings in autopsies.

    Behçet's disease (BD) is a multisystem disorder. The main pathology in BD is vasculitis that involves arteries and veins of all calibers. Central nervous system involvement occurs in 5-10% of patients. Increased morbidity and mortality is rarely observed in children. The mean age at onset in pediatric BD is approximately 7 years. Neurologic involvement in BD is usually observed after 3-6 years. We report the case of a four-year-old Turkish boy with BD with sagittal sinus thrombosis treated with infliximab. The patient presented papilledema without neurologic signs. Although long-term efficacy evaluations are needed in this case, infliximab therapy may be a good option in childhood BD with refractory sinus thrombosis. This is the youngest case of BD with sagittal sinus thrombosis reported so far. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    Neuro-ophthalmology as a specialty is underdeveloped in India. The aim of our study was to determine the spectrum and profile of patients presenting to a tertiary eye care center with neuro-ophthalmic disorders. A retrospective hospital-based study was conducted, and records of all patients seen at the neuro-ophthalmology clinic of Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India, over a 1-year period were retrieved and evaluated. Of a total of 30,111 patients referred to various specialty clinics in a span of 1 year, 1597 (5%) were referred for neuro-ophthalmology evaluation. The mean patient age was 30.8 ± 19.5 years, with a male dominance (M:F = 2.02:1). Among these patients, optic nerve disorders were noted in 63.8% (n = 1,020), cranial nerve palsy in 7% (n = 114), cortical visual impairment in 6.5% (n = 105), and others (eye/optic nerve hypophasia, blepharospasm, and optic disc drusen) in 6% (n = 95). Among the patients with optic nerve disorders, optic neuropathy without disc edema/(traumatic optic neuropathy, hereditary, tumor-related, retrobulbar neuritis, toxic, and idiopathic) was noted in 42.8% (n = 685) and optic neuropathy with disc edema (ischemic optic neuropathy, papilledema, post-papilledema optic atrophy, papillitis, neuroretinitis, and inflammatory optic neuropathy) in 20.9% (n = 335). Sixteen percent of patients (n = 263) were incorrect referrals. The neuro-ophthalmic clinic constitutes a significant referral unit in a tertiary eye care center in India. Traumatic and ischemic optic neuropathies are the most common diagnoses. Neuro-ophthalmology requires further development as a subspecialty in India to better serve the nation's population.

  4. Computational Models of the Eye and their Applications in Long Duration Space Flight

    Astronauts are exposed to cephalad fluid shift, increased carbon dioxide levels and other environmental factors during space flight. As a result of these conditions, it is believed that they are at risk of developing increased intracranial pressure (ICP) and intraocular pressure (IOP), which in turn may cause papilledema and other disorders of the eye that can lead to temporary or permanent changes in vision. However, the mechanisms behind this risk are not fully understood. Ground analog and flight studies pose challenges because there are limited non-invasive methods that can be used to study the eye and intracranial space. Therefore it is proposed that computational models can be applied to help address this gap by providing a low cost method for studying the effects of IOP, ICP and various properties of the eye on these diseases. The information presented by the authors provides a summary of several models found in literature that could potentially be augmented and applied to inform research. Specifically, finite element models of the optic nerve head, sclera and other structures of the eye can be readily adapted as potential building blocks. These models may also be integrated with a brain/cerebrospinal fluid (CSF) model which will take into account the interaction between the CSF fluid and its pressure on the optic nerve. This integration can enable the study of the effects of microgravity on the interaction between the vasculature system and CSF system and can determine the effects of these changes on the optic nerve, and in turn the eye. Ultimately, it can help pinpoint the influences of long-term exposure to microgravity on vision and inform the future research into countermeasure development. In addition to spaceflight, these models can provide deeper understanding of the mechanisms of glaucoma, papilledema and other eye disorders observed in terrestrial conditions.

    Full Text Available Purpose: To describe visual loss at presentation in children with pseudotumor cerebri (PTC, and discuss mechanisms of visual loss and distinguishing features of pediatric PTC. Materials and Methods: Two children with papilledema and visual complaints were referred for ophthalmic evaluation. Both patients underwent a detailed ophthalmic work-up. Results: Patient 1, an 8-year-old girl, presented with a 2-week history of headache, vomiting, and visual impairment in both eyes. The child had no previous medical history. Patient 2, a 9-year-old boy, experienced sudden loss of vision in both eyes one week prior to presentation, along with severe headache and vomiting. He had undergone a renal transplantation one year back, and his current medications included cyclosporine A (CsA and oral prednisolone. Extensive disc swelling, lipid exudation and retinal thickening in the posterior pole were observed in both patients. Lumbar puncture in both showed elevated cerebrospinal fluid pressure. Both were treated with oral acetazolamide. Patient 1 additionally received intravenous methylprednisolone followed by an oral taper. CsA was stopped in patient 2. PTC and papilledema resolved with above measures in both patients, with partial recovery of visual function. Conclusions: PTC in children may have atypical manifestations. Visual acuity may be compromised acutely due to several factors. Patients with PTC and severe visual loss at presentation mandate an aggressive management approach. Use of intravenous steroids may be considered along with acetazolamide. Despite resolution of PTC, sequelae such as optic atrophy or macular scarring may impede eventual visual recovery. Physicians following patients on CsA need to be aware of the possible neuro-ophthalmic complications of the drug.

    ICP was elevated (Fig. 2). In particular, c. 48 of simulations in the elevated ICP condition showed peak strains in the optic nerve that exceeded the strains expected on earth. Such extreme strains are likely important, since they represent a larger signal for mechano-responsive resident cells [2]. The models predicted little to no anterior motion of the prelaminar neural tissue (optic nerve swelling, or papilledema, secondary to axoplasmic stasis), typically seen with elevated ICP. Specialized FE models to capture axoplasmic stasis would be required to study papilledema. These results suggest that the most notable effect of elevated ICP may occur via direct optic nerve loading, rather than through connective tissue deformation. These FE models can inform the design of future studies designed to bridge the gap between biomechanics and pathophysiological function in VIIP.

    Intracranial fat-containing congenital tumors are characterized by negative absorption values on computed tomography(CT). We are reporting a case of teratoma with intraventricular free fat diagnosed preoperatively by CT. The case is a 19-year-old female who was admitted to our hospital because of continuous severe headache, nausea and vomiting. At the time of admission, her physical and neurological examination was negative except for bilateral papilledema. CT demonstrated marked enlargement of the right lateral ventricle. In addition, there was negative absorption value (-90 H.U.), suggesting free fat, within right frontal horn layering above the CSF with a fluid level. Metrizamide ventriculography demonstrated complete obstruction and revealed an irregular shadow defect at the right foramen of Monro. At surgery, yellowish cheese-like material, white hair was found on the surface of the CSF. Tumor arose from the floor of the right foramen of Monro and extended upward. The patient made an uneventful recovery and was discharged 17 days after surgery. Intraventricular free fat is likely that to be released from the teratoma cyst ruptured spontaneously when the patient complained of severe headache 40 days prior to admission. There have been several published reports of the CT appearances of intracranial fat-containing tumors, however, teratoma with intraventricular free fat is very rare. It was concluded that fat-containing tumors should be highly suspected, when negative absorption values were found on CT.

    Full Text Available Headache associated with neurological deficits and cerebrospinal fluid lymphocytosis (HaNDL is a self-limited syndrome characterized by sudden-onset headache with a temporary neurological deficit and cerebrospinal fluid (CSF lymphocytosis. We aimed to disscus a case of HaNDL syndrome presenting during pregnancy with relevant literature. A 20-year-old female presented with a 5-day history of severe, bilateral throbbing headache accompanied by nausea, vomiting, and phonophobia. Approximately 2 days after the pain developed, she became acutely confused for less than 90 minutes. 2 days after this episode, she experienced again confusional state and left hemiparesis. There were no symptoms consistent with meningoencephalitis. She was pregnant and at 11 weeks gestation. A neurologic examination showed confusional state, bilateral papilledema, and mild left hemiparesis. The neuroradiological examination was normal. The cerebrospinal fluid revealed lymphocytic pleocytosis, mildly elevated protein, and increased opening pressure. She recovered completely after 8 days. The precise etiology of HaNDL is unknown, although an inflammatory or infectious origin and autoimmune factors have been proposed. Moreover, the risk factors and medical conditions associated with HaNDL are unknown. It is obviously difficult to determine whether the pregnancy was coincidental or associated in this case. We believe that comprehensive studies are needed to clarify the risk factors and medical conditions associated with HaNDL

    To investigate the impact of endoscope-assisted microsurgical fenestration on temporal arachnoid cysts, and to determine the advantages and limitations of the technique. Twenty-five children with symptomatic temporal arachnoid cysts were operated via eyebrow supraorbital keyhole microsurgical fenestration targeting the medial cyst wall. Preoperative magnetic resonance imaging (MRI) of the brain was done for all patients. Preoperative clinical presentation of the patients included headache (80%), nausea & vomiting (64%), drug resistant epilepsy (52%), macrocephaly (12%) papilledema (28%), motor weakness in the form of right-sided hemiparesis (12%) and cranial nerve palsy. Postoperative complete subsidence of headache was noted in 50%, while 20% remained unchanged. Drug resistant epilepsy improved in 69% of the patients. Postoperative MRI showed initial decrease in cyst volume as early as 3 months, only in a range of 5-12% volume reduction, and the late follow-up done at 6 and 18 months continued to show further reduction reported to be significant (p CSF) collection was the most common complication (20%). Only 1 patient experienced CSF leak mandating cysto-peritoneal shunting. Conclusıon: Eyebrow supraorbital keyhole microsurgical fenestration for temporal arachnoid cysts can be performed with a fairly low risk of complications and yields a favorable improvement in clinical and neuroimaging outcomes.

    We present our experience over the long-term of monitoring of visual function in children with craniopharyngioma. Our study involves an analysis of all paediatric patients with craniopharyngioma younger than 16 at the time of diagnosis and represents a series of predominantly sub-totally resected tumours. Visual data, of multiple modality, of the paediatric patients was collected. Twenty patients were surveyed. Poor prognostic indicators of the visual outcome and rate of recurrence were assessed. Severe visual loss and papilledema at the time of diagnosis were more common in children under the age of 6. In our study visual signs, tumour calcification and optic disc atrophy at presentation are predictors of poor visual outcome with the first two applying only in children younger than 6. In contrast with previous reports, preoperative visual field (VF) defects and type of surgery were not documented as prognostic indicators of poor postoperative visual acuity (VA) and VF. Contrary to previous reports calcification at diagnosis, type of surgery and preoperative VF defects were not found to be associated with tumour recurrence. Local recurrence is common. Younger age at presentation is associated with a tendency to recur. Magnetic resonance imaging (MRI) remains the recommended means of follow-up in patients with craniopharyngioma.

    2015-02-01

    Pseudotumor cerebri syndrome (PTCS) is defined by the presence of elevated intracranial pressure (ICP) in the setting of normal brain parenchyma and cerebrospinal fluid (CSF). Headache, vision changes, and papilledema are common presenting features. Up to 10% of appropriately treated patients may experience permanent visual loss. The mechanism(s) underlying PTCS is unknown. PTCS occurs in association with a variety of conditions, including kidney disease, obesity, and adrenal insufficiency, suggesting endocrine and/or metabolic derangements may occur. Recent studies suggest that fluid and electrolyte balance in renal epithelia is regulated by a complex interaction of metabolic and hormonal factors; these cells share many of the same features as the choroid plexus cells in the central nervous system (CNS) responsible for regulation of CSF dynamics. Thus, we posit that similar factors may influence CSF dynamics in both types of fluid-sensitive tissues. Specifically, we hypothesize that, in patients with PTCS, mitochondrial metabolites (glutamate, succinate) and steroid hormones (cortisol, aldosterone) regulate CSF production and/or absorption. In this integrated mechanism review, we consider the clinical and molecular evidence for each metabolite and hormone in turn. We illustrate how related intracellular signaling cascades may converge in the choroid plexus, drawing on evidence from functionally similar tissues.

    What is the risk? Given that astronauts exposed to microgravity experience a cephalad fluid shift, and that both symptomatic and asymptomatic astronauts have exhibited optic nerve sheath edema on MRI, there is a high probability that all astronauts have some degree of increased intracranial pressure (ICP; intracranial hypertension), and that those susceptible (via eye architecture, anatomy, narrow optic disc) have a high likelihood of developing papilledema (optic disc edema, globe flattening), choroidal folds, and/or hyperopic shifts and that the degree of edema may determine long-term or permanent vision impairment or loss. Back to back panels on this topic have been developed to address this emerging risk. The first panel will focus on the 6 clinical cases with emphasis on ophthalmic findings and imaging techniques used pre-, in-, and post-flight. The second panel will discuss the operational mitigation and medical requirements, the potential role of CO2 on ISS, and the research approach being developed. In total these back to back panels will explore what is known about this risk, what has been done immediately to address it, and how an integrated research model is being developed.

Obese females of reproductive age are predominantly affected, but the underlying pathological mechanisms behind IIH remain unknown. This review provides an overview of pathogenic factors that could result in IIH with particular focus on hormones and the impact of obesity, including its role in neuroendocrine signaling and driving inflammation. Despite occurring almost exclusively in obese women, there have been a few studies evaluating the mechanisms by which hormones and adipokines exert their effects on ICP regulation in IIH. Research involving 11ß-hydroxysteroid dehydrogenase type 1, a modulator of glucocorticoids, suggests a potential role in IIH. Improved understanding of the complex interplay between adipose signaling factors such as adipokines, steroid hormones, and ICP regulation may be key to the understanding and future management of IIH.

    While 40 years of human spaceflight exploration has reported visual decrement to a certain extent in a subgroup of astronauts, recent data suggests that there is indeed a subset of crewmembers that experience refraction changes (hyperoptic shift), cotton wool spot formation, choroidal fold development, papilledema, optic nerve sheath distention and/or posterior globe flattening with varying degrees of severity and permanence. Pre and postflight ocular measures have identified a potential risk of permanent visual changes as a result of microgravity exposure, which has been defined as the Visual Impairment and Intracranial Pressure risk (VIIP). The combination of symptoms are referred to as the VIIP syndrome. It is thought that the ocular structural and optic nerve changes are caused by events precipitated by the cephalad fluid shift crewmembers experience during long-duration spaceflight. Three important systems, ocular, cardiovascular, and central nervous, seem to be involved in the development of symptoms, but the etiology is still under speculation. It is believed that some crewmembers are more susceptible to these changes due to genetic/anatomical predisposition or lifestyle (fitness) related factors. Future research will focus on determining the etiology of the VIIP syndrome and development of mechanisms to mitigate the spaceflight risk.

    This is a survey of the long-term result after various surgical treatments in a child with microcephalic osteodysplastic primordial dwarfism type II (MOPD II) and craniosynostosis. We report a 17-year-old patient with MOPD II but some unusual clinical signs including bilateral knee dislocation, a misplaced upper lobe bronchus, and hypoplasia of the anterior corpus callosum. Because of premature fusion of several cranial sutures, the child developed signs of increased intracranial pressure with somnolence and papilledema. Cranial vault remodeling with fronto-orbital advancement was performed twice at the age of 16 and 21 months to open the abnormally closed suture, increase the intracranial volume, and relieve the elevated intracranial pressure. Following this procedure, the child's neurologic situation recovered significantly. Surgical procedure of fronto-orbital advancement and the performed reoperation in our patient were safe with no major complications intraoperatively and postoperatively with good functional and satisfying aesthetic outcomes in the long-term follow-up, expressed by the patient, his parents, and the surgeons.

    A 14-year-old male presented with bilateral papilledema, growth retardation and absent secondary sexual characters. He had a past history of fever, headache and fatigue of 6 months duration. The diagnosis of intracranial hypertension (IH) was confirmed by an increased intracranial pressure and normal neuroimaging studies of the brain, except for partial empty sella, prominent perioptic cerebrospinal fluid (CSF) spaces and buckling of optic nerves. Evaluation showed erythrocyte sedimentation rate (ESR) of 150 mm/hr, positive antinuclear antibody (ANA), anti dsDNA and anti ribosomal P protein. Renal biopsy revealed diffuse segmental proliferative lupus nephritis (LN) class IV S (A) confirming the diagnosis of systemic lupus erythematosus (SLE). Treatment of LN with intravenous pulse methyl prednisolone and cyclophosphamide was effective in normalizing the CSF pressure, resulting in express and dramatic resolution of symptomatology. In a case of IH, SLE must be considered. IH, growth retardation and absence of sexual characters may be presenting manifestations of a chronic systemic inflammatory disease like SLE. These manifestations may act as a pointer to associated advanced grades of LN, which can be totally asymptomatic and missed without a renal biopsy.

    Objective was to describe the clinical features of 5 patients with rare atypical presentation of idiopathic intracranial hypertension (IIH), and propose the possible mechanism of this atypical presentation. We carried out a retrospective study of 5 patients, admitted at King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia with IIH during the period from January 2001 to December 2005. All were females with their age ranges from 24 to 40 years. The clinical presentations, the laboratory and imaging studies were analyzed. The opening pressures of the lumbar puncture tests were documented. All patients were presented with headache. One had typical pain of trigeminal neuralgia and one with neck pain and radiculopathy. Facial diplegia was present in one patient and two patients had bilateral 6th cranial neuropathy. Papilledema was present in all patients except in one patient. Imaging study was normal in all patients, and they had a very high opening pressure during lumbar puncture, except in one patient. All patients achieved full recovery with medical therapy in 6 to 12 weeks with no relapse during the mean follow up of 2 years. Atypical finding in IIH are rare and require a high index of suspicion for early diagnosis. (author)

    While moderate and severe back or extremity pain is frequent in Guillain-Barré syndrome (GBS), headache appears to be uncommon. Most of the reports of headache in GBS place it in the context of the posterior reversible encephalopathy syndrome (PRES) which is increasingly recognized as a likely dysautonomia-related GBS complication. There are also a few reports of headache in the setting of increased CSF pressure and papilledema and in association with the Miller Fisher GBS variant. In comparison, back and extremity pain is highly prevalent. Aching muscle pain and neuropathic pain are the two most common of several pain types. Pain may be a heralding feature and has been described in patients as long as 2 years after disease onset. Pain management is a major axis of treatment in GBS. Gabapentin is a reasonable first-line choice, and opioid medications can be added for more severe pain but there are few clinical trials to inform specific recommendations. While the understanding of pain pathophysiology in GBS is incomplete, its prevalence and clinical impact are increasingly recognized and studied. Pain should be considered a cardinal manifestation of GBS along with acute, mostly symmetric weakness and diminished reflexes.

    This slide presentation is an overview of the some of the known results of spaceflight induced intracranial hypertension. Historical information from Gemini 5, Apollo, and the space shuttle programs indicated that some vision impairment was reported and a comparison between these historical missions and present missions is included. Optic Disc Edema, Globe Flattening, Choroidal Folds, Hyperopic Shifts and Raised Intracranial Pressure has occurred in Astronauts During and After Long Duration Space Flight. Views illustrate the occurrence of Optic Disc Edema, Globe Flattening, and Choroidal Folds. There are views of the Arachnoid Granulations and Venous return, and the question of spinal or venous compliance issues is discussed. The question of increased blood flow and its relation to increased Cerebrospinal fluid (CSF) is raised. Most observed on-orbit papilledema does not progress, and this might be a function of plateau homeostasis for the higher level of intracranial pressure. There are seven cases of astronauts experiencing in flight and post flight symptoms, which are summarized and follow-up is reviewed along with a comparison of the treatment options. The question is "is there other involvement besides vision," and other Clinical implications are raised,

    Arrested hydrocephalus is stable ventriculomegaly without evidence of neurologic deterioration or symptoms. Management of arrested hydrocephalus in asymptomatic adults is controversial, with little clinical data. This case highlights the potential for decompensation in adults with arrested hydrocephalus and reviews the literature regarding pathophysiology and management of this clinical entity. A 39 year-old gentleman with arrested hydrocephalus incidentally found during work-up for new-onset seizure and managed conservatively for ten years presented with increasing headache, memory loss, gait instability and urinary and fecal incontinence. Stable massive triventriculomegaly was documented on serial brain imaging, and ophthalmologic exam revealed no papilledema. The patient underwent endoscopic third ventriculostomy with immediate post-operative improvement of headache, resolution of incontinence, and cessation of seizures. At 15 months after surgery, neuropsychiatric testing demonstrated improvement in visuomotor skills, problem solving, verbal fluency and cognitive flexibility compared to his pre-operative baseline. At 18 months after surgery he remained seizure free with full continence and significant improvement in headaches. Early recognition of arrested hydrocephalus and its potential for decompensation may prompt surgical treatment and prevent neurologic deterioration. Copyright © 2016 Elsevier B.V.

    Full Text Available Abstract Introduction Cystic fibrosis, an epithelial cell transport disorder caused by mutations of the cystic fibrosis transmembrane conductance regulator gene, is not generally associated with malformations of the central nervous system. We review eight previously published reports detailing an infrequent association between cystic fibrosis and Chiari I malformation. Case presentation To the best of our knowledge, our report describes only the ninth case of a baby presenting with a new diagnosis of cystic fibrosis and Chiari I malformation, in this case in a 10-month-old, full-term Caucasian baby boy from the United States of America. Neurosurgical consultation was obtained for associated developmental delay, macrocephaly, bulging anterior fontanel, and papilledema. An MRI scan demonstrated an extensive Chiari I malformation with effacement of the fourth ventricle, obliteration of the outlets of the fourth ventricle and triventricular hydrocephalus without aqueductal stenosis. Our patient was taken to the operating room for ventriculoperitoneal shunt placement. Conclusions It is possible that the cystic fibrosis transmembrane conductance regulator gene may play a previously unrecognized role in central nervous system development; alternatively, this central nervous system abnormality may have been acquired due to constant valsalva from recurrent coughing or wheezing or metabolic and electrolyte imbalances that occur characteristically in cystic fibrosis.

    It is important to perform CT purposefully in patients with some neuro-ophthalmological disorders. Using Hitachi CT-H250 with the finer matrix of 256 x 256 and a section thickness of 5 mm and 10 mm, we performed head CT in 98 patients with various kinds of neuro-ophthalmological disorders in these 30 months. Neuro-ophthalmological findings in these patients were visual disturbance, visual field defects (hemianopsia, quandrantanopsia, enlargement of the blind spot, central scotoma), papilledema, optic nerve atrophy, difficulties in ocular movements, and others. In 44 (44.9%) of these 98 patients, abnormal findings were displayed in the head CT, characterizing intracranial tumors, intracranial infarction, aneurysms in intracranial vessels, arterio-venous malformation, enlargement of the ventricle or the cistern. In some cases the head CT was the decisive procedure in ensuring a correct diagnosis. We presented findings in the head CT in several interesting cases. We recognized the necessity of the head CT in patients with neuro-ophthalmological disorders. (author)

    Intracranial fat-containing congenital tumors are characterized by negative absorption values on computed tomography(CT). We are reporting a case of teratoma with intraventricular free fat diagnosed preoperatively by CT. The case is a 19-year-old female who was admitted to our hospital because of contineous severe headache, nausea and vomiting. At the time of admission, her physical and neurological examination was negative except for bilateral papilledema. CT demonstrated marked enlargement of the right lateral ventricle. In addition, there was negative absorption value (-90 H.U.), suggesting free fat, within right frontal horn layering above the CSF with a fluid level. Metrizamide ventriculography demonstrated complete obstruction and revealed an irregular shadow defect at the right foramen of Monro. At surgery, yellowish cheese-like material, white hair was found on the surface of the CSF. Tumor arose from the floor of the right foramen of Monro and extended upward. The patient made an uneventful recovery and was discharged 17 days after surgery. Intraventricular free fat is likely that to be released from the teratoma cyst ruptured spontaneously when the patient complained of severe headache 40 days prior to admission. There have been several published reports of the CT appearances of intracranial fat-containing tumors, however, teratoma with intraventricular free fat is very rare. It was concluded that fat-containing tumors should be highly suspected, when negative absorption values were found on CT. (author)

    Idiopathic intracranial hypertension (IIH) is a rare neurologic disorder. It is also known as pseudotumor cerebri. The incidence of IIH is one to two per 100,000 population annually. The higher incidence is in obese women from 15 to 44 years. The main symptoms are headache and visual loss. It mostly affects women of childbearing age who are overweight or obese. There are many theories of pathogenesis of IIH, but precise pathogenesis is unknown. One of the causes of IIH is intracranial venous sinus thrombosis. It can cause increased cerebrospinal fluid (CSF) pressure by obstruction of venous outflow and blocking of CSF absorption. In polycystic ovary syndrome (PCOS) patients, thrombogenic tendency is increased due to increased aromatization of testosterone to estradiol which could induce estrogen-mediated thrombophilia. The authors present a 14-year-old girl with PCOS stigma who presented with a severe headache and papilledema. These symptoms were not improved by standard medical therapy of IIH and PCOS, but improved after laparoscopic ovarian drilling. The authors report it with a review of the literature.

    Optic nerve fenestration is carried out in cases of severe benign intracranial hypertension. This study aimed to monitor the optic nerve sheath appearances and orbital changes that occur following this procedure. The eight patients were all female with an average age of 37.3 years and a range of 20-58 years. The duration of symptoms was 2-6 years. Symptoms included headaches, diplopia and visual obscurations. Examination revealed severe papilledema. All investigations, including MRI, biochemical and immunological tests, were negative. Patients had fenestration of a 2 mm x 3 mm segment of the medial aspect of the optic nerve sheath. Imaging was obtained with a 1 T MRI machine using a head coil. Coronal, axial and sagittal 3 mm contiguous sections using STIR sequences with TR 4900 ms, IT 150 ms and TE 60 ms were obtained. Five patients showed clinical improvement. The post-operative MRI findings in four of these included a decreased volume of cerebrospinal fluid (CSF) around the optic nerve sheaths and a localized collection of fluid within the orbit. There were no MRI changes in the three patients with no clinical improvement. Decreased CSF volume around the optic nerve and a fluid collection within the orbit may indicate a favorable outcome in optic nerve fenestration. (orig.) With 3 figs., 12 refs.

    Idiopathic intracranial hypertension (IIH) in patients with Cushing disease (CD), after treatment, is rarely described, in adults. The cause is believed to be multifactorial, potentially related to a relative decrease in cortisol after surgical resection or medical treatment of a corticotroph pituitary adenoma. We investigate our center's CD database (140 surgically and 60 medically [primary or adjunct] treated patients) for cases of IIH, describe our center's experience with symptomatic IIH, and review treatment strategies in adults with CD after transsphenoidal resection. We present the case of a 22-year-old woman who presented with worsening headache, nausea, vomiting, blurry vision, diplopia, visual loss, and facial numbness 14 weeks after surgical resection of adrenocorticotropic hormone-positive pituitary adenoma. Her CD had been in remission since surgery, with subsequent adrenal insufficiency (AI), which was initially treated with supraphysiologic glucocorticoid replacement, tapered down to physiologic doses at the time the IIH symptoms developed. Symptomatic IIH is rare in adult patients but can be severe and result in permanent vision loss. A high index of suspicion should be maintained and a fundus examination is necessary to exclude papilledema, whenever there are suggestive symptoms that initially may overlap with AI. It is possible that some cases of mild IIH are misdiagnosed as GC withdrawal or AI; however, further studies are needed. Treatment consists of reinitiation of higher steroid doses together with acetazolamide with or without cerebrospinal fluid diversion and the priority is to preserve vision and reverse any visual loss.

    Twelve Macaca mulatta monkeys received 200 rads of supervoltage radiation to the whole brain per day, 5 days a week. The course in four monkeys was 4 weeks for a total dose of 4000 rads; in four monkeys, 6 weeks for 6000 rads; and in four monkeys, 8 weeks for 8000 rads. Four unirradiated monkeys served as controls. One from each group, sacrificed at 6 and 12 months from start of irradiation, is reported here. The results from 4000 rads were negligible; those from 8000 rads, profound, with gross brain destruction. The results from 6000 rads, within the therapeutic range, included at 6 months punctate necrotic lesions, 1 mm or less, widely scattered but with a predilection for the forebrain white matter. The reaction to these lesions ranged from an early macrophage response to calcification. Some were accompanied by focal edema. There were occasional examples of vascular endothelial proliferation. In addition, there were patches of dilated capillaries or telangiectasia. Twelve months after 6000 rads there were a few mineralized lesions and innumerable minute deposits of calcium and iron. A more active process was suggested by widely disseminated areas of telangiectasia, 6 to 12 mm in extent. The clinical course from this exposure included papilledema from the third to the sixth month and depressed visual evoked response accompanied by delta activity in the electroencephalogram from the sixth to the twelfth month

    An increased risk of venous thromboembolism has been demonstrated following renal transplantation. Commonly reported sites have been deep vein thrombosis, pulmonary thromboembolism and vascular thrombosis involving the graft. Cerebral venous thrombosis (CVT) has not been reported in literature so far. A 36-year-old male patient, transplanted in January 2005 with normal graft functions, was admitted with history of headache, blurring of vision and vomiting. Examination revealed papilledema and no neurological deficits. Baseline investigations and analysis of cerebrospinal liquid were normal. Cerebral magnetic resonance venogram revealed extensive CVT involving superior sagittal sinus, bilateral transverse sinuses and the right sigmoid sinus. He was investigated for a thrombophilic disorder; serum homocysteine, protein C and S levels, antiphospholipid antibody and antithrombin-III levels were done despite which no conclusive diagnosis could be arrived at. To our knowledge, this is the first report of extensive CVT described in a transplant recipient. Ne definite prothrombotic or predisposing factors could be identified in our patient and the cause of CVT remains unclear. (author)

     Dandy Walker Syndrome is a congenital abnormality in the central nervous system, characterized by a deficiency in the development of middle cerebelar structures, cystic dilatation of the posterior pit communicating with the fourth ventricle and upward shift of the transverse sinuses, tentorium and dyes. Among the clinical signs are occipital protuberances, a progressive increase of the skull, bowing before the fontanels, papilledema, ataxia, gait disturbances, nystagmus, and intellectual impairment.  To describe a case of female patient, 13 years old with a diagnosis of this syndrome and bilateral hearing loss underwent cochlear implant surgery under local anesthesia and sedation.  CGS, 13 years old female was referred to the Otolaryngological Department of Otolaryngology Institute of Parana with a diagnosis of "Dandy-Walker syndrome" for Otolaryngological evaluation for bilateral hearing loss with no response to the use of hearing aids. Final Comments: The field of cochlear implants is growing rapidly. We believe that the presence of Dandy-Walker syndrome cannot be considered a contraindication to the performance of cochlear implant surgery, and there were no surgical complications due to neurological disorders with very favorable results for the patient who exhibits excellent discrimination. It has less need for lip reading with improvement in speech quality.

    The retinal nerve fiber layer thickness (RNFLT) in patients with optic disc swelling of different etiologies was compared using scanning laser polarimetry (SLP) and spectral-domain optical coherence tomography (OCT). Forty-seven patients with optic disc swelling participated in the cross-sectional study. Both GDx SLP (enhanced corneal compensation) and Spectralis spectral-domain OCT measurements of RNFLT were made in 19 eyes with papilledema (PE), ten eyes with optic neuritis (ON), and 18 eyes with nonarteritic anterior ischemic optic neuropathy (NAION) at the neuro-ophthalmology clinic at Kyoto University Hospital. Differences in SLP (SLP-RNFLT) and OCT (OCT-RNFLT) measurements among different etiologies were investigated. No statistical differences in average OCT-RNFLT among PE, ON, and NAION patients were noted. Average SLP-RNFLT in NAION patients was smaller than in PE (P<0.01) or ON (P=0.02) patients. When RNFLT in each retinal quadrant was compared, no difference among etiologies was noted on OCT, but on SLP, the superior quadrant was thinner in NAION than in PE (P<0.001) or ON (P=0.001) patients. Compared with age-adjusted normative data of SLP-RNFLT, average SLP-RNFLT in PE (P<0.01) and ON (P<0.01) patients was greater. Superior SLP-RNFLT in NAION patients was smaller (P=0.026). The ratio of average SLP-RNFLT to average OCT-RNFLT was smaller in NAION than in PE (P=0.001) patients. In the setting of RNFL thickening, despite increased light retardance in PE and ON eyes, SLP revealed that NAION eyes have less retardance, possibly associated with ischemic axonal loss.

    An unusual case of peritumoral hemorrhage after radiosurgery for the treatment of metastatic brain tumor is reported. This 64-year-old woman had a history of breast cancer and underwent right mastectomy in 1989. She remained well until January 1993, when she started to have headache, nausea and speech disturbance, and was hospitalized on February 25, 1993. Neurological examination disclosed right hemiparesis and bilateral papilledema. CT scan and MR imaging showed a solitary round mass lesion in the left basal ganglia region. It was a well-demarcated, highly enhanced mass, 37 mm in diameter. Cerebral angiography confirmed a highly vascular mass lesion in the same location. She was treated with radiosurgery on March 8 (maximum dose was 20 Gy in the center and 10 Gy in the peripheral part of the tumor). After radiosurgery, she had an uneventful course and clinical and radiosurgical improvement could be detected. Her neurological symptoms and signs gradually improved and reduction of the tumor size and perifocal edema could be seen one month after radiosurgery. However, 6 weeks after radiosurgery, she suddenly developed semicoma and right hemiplegia. CT scan disclosed a massive peritumoral hemorrhage. Then, emergency craniotomy, evacuation of the hematoma and total removal of the tumor were performed on April 24. Histopathological diagnosis was adenocarcinoma. It was the same finding as that of the previous breast cancer. Histopathological examination revealed necrosis without tumor cells in the center and residual tumor cells in the peripheral part of the tumor. It is postulated that peritumoral hemorrhage was caused by hemodynamic changes in the vascular-rich tumor after radiosurgery and breakdown of the fragile abnormal vessels in the peripheral part of the tumor.

    Idiopathic intracranial hypertension (IIH) may lead to visual impairment. Shunt surgery is indicated for refractory IIH-related symptoms that persist despite medical treatment, or those presenting with significant visual decline. Obesity is a risk factor for IIH; a reduction in weight has been shown to improve papilledema. Bariatric surgery (BS) has been suggested for treating IIH associated with morbid obesity. In this study, we describe a high rate of over-drainage (OD) seen in patients following shunts and BS. The study cohort includes 13 patients with IIH that underwent shunt surgery for treatment of the IIH-related symptoms. Six patients underwent BS in addition to the shunt surgery (but not concomitantly). Seven patients had only shunt surgeries with no BS. Data were collected retrospectively. BS effectively led to weight reduction (body mass index decreasing from 43 ± 4 to 28 ± 5). Patients undergoing BS had 1-6 (2.5 ± 1.9) shunt revisions for OD following BS, as opposed to 0-3 (1.4 ± 1.1) revisions prior to BS over similar time spans (statistically insignificant difference), and 0-6 (1.6 ± 2.5) revisions among the non-BS patients over a longer time span (statistically insignificant difference). Two patients in the BS group underwent shunt externalization and closure; however, they proved to be shunt-dependent. Patients with IIH that undergo shunt surgery and BS (not concomitantly) may suffer from OD symptoms, necessitating multiple shunt revisions, and valve upgrades. Despite BS being a valid primary treatment for some patients with IIH, among shunted patients, BS may not lead to resolution of IIH-related symptoms and patients may remain shunt-dependent.

    Full Text Available Abstract Neuro-Behçet’s disease (NBD involves the central nervous system; peripheral nervous system involvement is not often reported. NBD is quite common in adult patients and occurs rarely during childhood and adolescence. Young patients may share symptoms and signs of NBD with other neuro-ophthalmological disorders (e.g. idiopathic intracranial hypertension; thus, making the differential diagnosis difficult. Neuroimaging is mandatory and necessary for a correct NBD diagnosis but in children radiological examinations are often difficult to perform without sedation. From 1971 to 2011, 130 patients aged ≤16 years have been reported with NBD, according to retrospective surveys, case series, and case reports. The origin of the reported cases met the well-known geographical distribution of Behçet’s disease (BD; the mean age at presentation of neurological findings was 11.8 years, with male gender prevalence (ratio, 2.9:1. We considered in detail the neuro-ophthalmological features of the 53 cases whose neuroimaging alterations were described with an assigned radiological pattern of the disease (parenchymal: 14 cases, non-parechymal: 35 cases, and mixed: 4 cases. In 19/53 patients (36%, neuro-ophthalmological symptoms anticipated any pathognomonic sign for a BD diagnosis, or only occasional aphtae were recalled by the patients. Family history was positive in 17% of subjects. Headache was reported in 75% of the patients; in those presenting with cerebral vascular involvement, headache was combined to other symptoms of intracranial hypertension. Papilledema was the most frequently reported ophthalmological finding, followed by posterior uveitis. Treatment consisted of systemic steroids in 93% of patients, often combined with other immunosuppressive drugs (especially colchicine and azathioprine. Clinical recovery or improvement was documented in the large majority of patients. Nine subjects had definitive alterations, and one died. Based on our

    We investigated the clinical characteristics of a pediatric population with hemato-oncological disease and intracranial hypertension, analyze the therapeutic response and outcome, and compare its characteristics with respect to a control group with idiopathic intracranial hypertension. We retrospectively analyzed patients with hemato-oncological disease and secondary intracranial hypertension in our center during the past five years. We compared these individuals with a historical cohort with idiopathic intracranial hypertension from our institution (control group). We identified eight patients, all with leukemia, and 21 controls. Mean age at diagnosis was 10.6 years, and 62% of individuals were female. Most of them were under treatment with drugs (62% corticosteroids, 75% active chemotherapy). Mean opening pressure of cerebrospinal fluid was 35 cm H 2 O. All had headache, but only 28% complained of visual symptoms. Only 12.5% exhibited papilledema at the time of diagnosis (versus 71% in controls). All of them were treated with acetazolamide, with average therapy duration of nine months, and all had a favorable outcome (versus 57% of controls who needed second-line treatment). None of them showed long-term visual complications (versus 20% of controls). Patients with hemato-oncological disease and secondary intracranial hypertension may not develop typical symptomatology. Thus, diagnosis and recognition of this entity among this cohort may be difficult. Associated factors are diverse and do not show an obvious causal relationship. A high index of suspicion must be maintained for diagnosis, because a favorable outcome is expected with prompt treatment. Acetazolamide is effective as a first-line therapy and caused few side effects. Copyright © 2017 Elsevier Inc. All rights reserved.

    The olfactory groove meningioma has always been surgically challenging. The common microscopic surgical procedures exercised involve modification of pterional or sub-frontal approaches with or without orbital osteotomies. However, we believe that orbital osteotomies are not mandatory to achieve gross total resection. Hence, this study was performed to evaluate the surgical outcomes of olfactory groove meningioma with bicoronal sub frontal approach but without orbital osteotomies. The study was performed by reviewing the medical charts, neuroimaging data, and follow-up data of 19 patients who were treated micro surgically for olfactory groove meningioma without orbital osteotomies in our department. Mean overall follow up period of our study was 5 years. Statistical analysis was done by means of IBM SPSS Software version 19. Nineteen patients (1 male and 18 female patients, with an age range of 35-67 years; average age of patients' 51±7.5 years) of OGM were managed in our department. All patients were evaluated by MRI Brain with and without Gadolinium, CTA, CT Scan both axial and Coronal sequences. Most common symptom reported was head ache (80%), others include; urinary incontinence (26%), seizures (78%), decreased visual acuity (79%), papilledema (74%), personality changes (68%) and olfactory loss was reported in 57% of the patients. Post-operative complications include; CSF accumulation (5%), hematoma at tumor bed (10%), skin infection (5%) and mild post-operative brain edema (26%). Mortality rate was 5%. During 5 years of follow-up, we recorded one recurrence which was after 26 months and successfully removed in reoperation. Bi-coronal sub frontal approach appears to be an excellent technique for Olfactory Meningioma removal as practiced by most neurosurgeons. Nevertheless, it is not mandatory to carry out orbital osteotomy to acquire optimal surgical outcome as is advocated by some Authors.

    Full Text Available Abstract Introduction We report three cases of demyelinating disease with tumor-like presentation. This information is particularly important to both neurosurgeons and neurologists who should be aware that inflammatory demyelinating diseases can present as a mass lesion, which is indistinguishable from a tumor, both clinically and radiologically, especially when there is no evidence of temporal dissemination of this disease. Case presentation The first patient was a 42-year-old Malay woman who developed subacute onset of progressive quadriparesis with urinary incontinence. Magnetic resonance imaging of her spine showed an intramedullary lesion at the C5-C7 level. She was operated on and biopsy was suggestive of a demyelinating disease. Retrospective history discovered two episodes of acute onset of neurological deficits with partial recovery and magnetic resonance imaging of her brain revealed demyelinating plaques in the centrum semiovale. The second patient was a 16-year-old Malay boy who presented with symptoms of raised intracranial pressure. A computed tomography brain scan revealed obstructive hydrocephalus with a lesion adjacent to the fourth ventricle. An external ventricular drainage was inserted. Subsequently, a stereotactic biopsy was taken and histopathology was reported as demyelination. Retrospective history revealed similar episodes with full recovery in between episodes. The third case was a 28-year-old Malay man who presented with acute bilateral visual loss and confusion. Magnetic resonance imaging of his brain showed a large mass lesion in the right temporoparietal region. Biopsy was consistent with demyelinating disease. Reexamination of the patient revealed bilateral papillitis and not papilledema. Visual evoked potential was prolonged bilaterally. In all three cases, lumbar puncture for cerebrospinal fluid study was not carried out due to lack of patient consent. Conclusions These cases illustrate the importance of

    Full Text Available Abstract Background Primary diffuse leptomeningeal gliomatosis is a rare neoplasm confined to the meninges without evidence of primary tumor in the brain or spinal cord parenchyma. Cerebrospinal fluid diversion via ventriculoperitoneal shunt may be used as a therapeutic modality. Herein, we describe the first report of cytologic findings of a case of this neoplasm with shunt-related peritoneal metastasis. Case presentation A 19-year-old male presented with a 6-month history of severe headaches. He had bilateral papilledema on physical exam. Cerebrospinal fluid examination was negative. Four months later a ventriculoperitoneal shunt was placed. Shortly thereafter, he was diagnosed with primary diffuse leptomeningeal gliomatosis based on the biopsy of an intradural extramedullary lesion adjacent to the lumbar spinal cord at a referral cancer center. The histology featured an infiltrating growth pattern of pleomorphic astrocytes with diffuse positivity for glial fibrillary acidic protein. A couple of months later he presented at our institution with ascites and an anterior peritoneal mass. Repeat cerebrospinal fluid cytology and fine needle aspiration of the mass confirmed disseminated gliomatosis. Cytologic characteristics included clusters of anaplastic cells of variable size, high nuclear to cytoplasm ratio and scant to moderate cytoplasm. Occasional single bizarre multinucleated cells were seen with eccentric "partial wreath-like" nuclei, clumped chromatin and prominent nucleoli. Patient expired 13 months after initial presentation. Conclusion Disseminated primary diffuse leptomeningeal gliomatosis should be considered in the differential diagnosis of chronic aseptic meningitis and in the presence of a peritoneal tumor in patients with ventriculoperitoneal shunts. Immunocytochemistry may be of diagnostic value.

    Idiopathic intracranial hypertension is characterized by raised intracranial pressure (ICP) without any underlying pathology, presenting with (IIH) or without papilledema (IIHWOP). Headache, often on daily basis, is the most frequent symptom. Among audiovestibular symptoms, tinnitus and dizziness are commonly reported, while vertigo and hearing impairment are infrequent reports. Endolymphatic hydrops (ELH) is the typical histopathologic feature of Ménière disease, a condition featured by episodes of vertigo, dizziness, fluctuating hearing loss, tinnitus, and aural fullness. Evidences suggest that ICP is transmitted to inner ear. The aim of this study is to investigate the prevalence of ELH symptoms in IIH/IIHWOP and the relationship between the raised ICP and ELH. The prevalence of chronic headache and of ELH symptoms was investigated in a consecutive series of IIH/IIHWOP patients, and a standard audiometry with hearing threshold measurement (pure-tone average-PTA) was performed. Differences in chronic headache and ELH symptoms prevalence and changes of PTA threshold were calculated after ICP normalization by lumbar puncture (LP). Thirty-one patients (17 with IIH and 14 with IIHWOP) were included. Before LP, chronic headache was present in 93.5%. The percentages of patients reporting tinnitus, dizziness, vertigo, and aural fullness were 67.7, 77.4, 22.6, and 61.3%, respectively. Headache frequency as well as ELH symptoms and PTA significantly improved after LP. The improvement of PTA and of ELH symptoms observed after LP in this series of IIH/IIHWOP patients indicates that a raised ICP, a condition known to be involved in the progression and refractoriness of migraine pain, has also a role in ELH. We propose that intracranial hypertension may represent the shared pathogenetic step explaining the large epidemiological comorbidity between migraine and vestibular symptoms, at present conceptualized as "vestibular migraine."

    Full Text Available Background: Cerebral venous-sinus thrombosis is an uncommon form but important cause of stroke, especially in young-aged women. Methods: We performed a retrospective descriptive-analytical study in which 124 patients with cerebral venous-sinus thrombosis, who referred to Nemazee Hospital, Shiraz University of Medical Sciences from January 2000 to March 2008, were included, and their demographic, etiologic, radiological and prognostic characteristics were evaluated. Results: The patients' mean age was 34.01±10.25. Eighty seven (70.16% were women and 37 (29.83% were men. The most frequent clinical manifestations were headache, papilledema and seizures. Fifty seven (65.51% women took oral contraceptive pills. Twenty of 57 women (35.08% took the pill longer than one month to be able to fast in Ramadan or perform the Hajj ceremonies. In the mean time they developed cerebral venous-sinus thrombosis. Superior sagital sinus, with or without lateral sinuses, was the most involved area (70.96%. High mortality and morbidity rates (14.51% and 35.48%, respectively were found in patients. Poor prognostic factors at the time of admission were stupor and coma (P=0.001 and evidence of hemorrhage in primary CT scan (P=0.005. Conclusion: Taking oral contraceptive pills was a main factor associated with cerebral venous-sinus thrombosis. Clinical manifestations, prognostic factors, common involved sinuses and image findings of this study were similar to those of other studies. Health care policy makers should design a plan to warn susceptible women of the risk of cerebral venous-sinus thrombosis, and to educate them the ways to prevent it

    The widespread use of amiodarone is limited by its toxicity, notably to the optic nerve. We report two cases of bilateral optic nerve neuropathy due to amiodarone, and provide a detailed description of the disease. The first case was a 59-year-old man complaining from insidious monocular loss of vision within ten months of initiating amiodarone. Funduscopy and optical coherence tomography showed bilateral optic disc edema. The second case was a 72-year-old man presenting with a decrease in visual acuity in his left eye for a month. Funduscopy showed a left optic nerve edema, and fluorescein angiography showed bilateral papillitis. In both cases, the clinical presentation was not suggestive of ischemic neuropathy, because of the preservation of visual acuity and the insidious onset. In addition, both cardiovascular and inflammatory work-up were normal. An amiodarone-associated neuropathy was suspected, and amiodarone was discontinued with the approval of the cardiologist, with complete regression of the papilledema and a stabilization of visual symptoms. Differentiating between amiodarone-associated optic neuropathy and anterior ischemic optic neuropathy may be complicated by the cardiovascular background of such patients. The major criterion is the absence of a severe decrease in visual acuity; other criteria are the normality of cardiovascular and inflammatory work-up, and the improvement or the absence of worsening of symptoms after discontinuation of amiodarone. Amiodarone-associated neuropathy remains a diagnosis of exclusion, and requires amiodarone discontinuation, which can only be done with the approval of a cardiologist, and sometimes requires replacement therapy.

    Hepatitis C is a serious viral infection, for which the current treatment is based on the combination of pegylated interferon (IFN) and Ribavirin(®). Ophthalmic complications observed with PEG-IFN are infrequent and of variable prognosis. They often include an ischemic retinopathy with typical cotton-wool spots, hemorrhage and retinal edema, and rarely acute non-arteritic anterior ischemic optic neuropathy as illustrated by our report. We report the case of a 51-year-old man followed for chronic active hepatitis C, who presented in the fourth month of treatment with pegylated interferon and vidarabine with a sharp decline in visual acuity secondary to acute bilateral non-arteritic anterior ischemic optic neuropathy. The hepatitis C treatment was discontinued. His course was notable by the third week for a significant regression of papilledema with improvement in visual acuity in the right eye and no change in the left eye, remaining at counting fingers. After regressing for four years, the disease progressed to bilateral temporal optic atrophy without change in visual acuity. Pegylated interferon and Ribavirin(®) are commonly used in the treatment of chronic hepatitis C. They are the source of various ophthalmologic complications of varied severity. The pathophysiology of this ocular toxicity currently remains hypothetical. Non-arteritic ischemic optic neuropathy is still a relatively rare complication with a poor functional prognosis, often requiring discontinuation of treatment. Thus, careful ophthalmologic monitoring before and during antiviral treatment of patients with hepatitis C appears necessary. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Visual symptoms reported in astronauts returning from long duration missions in low Earth orbit, including hyperopic shift, choroidal folds, globe flattening and papilledema, are thought to be related to fluid shifts within the body due to microgravity exposure. Because of this possible relation to fluid shifts, safety considerations have been raised regarding the ocular health of head-down tilt (HDT) bed rest subjects. HDT is a widely used ground ]based analog that simulates physiological changes of spaceflight, including fluid shifts. Thus, vision monitoring has been performed in bed rest subjects in order to evaluate the safety of HDT with respect to vision health. Here we report ocular outcomes in 9 healthy subjects (age range: 27-48 years; Male/Female ratio: 8/1) completing bed rest Campaign 11, an integrated, multidisciplinary 70-day 6 degrees HDT bed rest study. Vision examinations were performed on a weekly basis, and consisted of office-based (2 pre- and 2 post-bed rest) and in-bed testing. The experimental design was a repeated measures design, with measurements for both eyes taken for each subject at each planned time point. Findings for the following tests were all reported as normal in each testing session for every subject: modified Amsler grid, red dot test, confrontational visual fields, color vision and fundus photography. Overall, no statistically significant differences were observed for any of the measures, except for both near and far visual acuity, which increased during the course of the study. This difference is not considered clinically relevant as may result from the effect of learning. Intraocular pressure results suggest a small increase at the beginning of the bed rest phase (p=0.059) and lesser increase at post-bed rest with respect to baseline (p=0.046). These preliminary results provide the basis for further analyses that will include correlations between intraocular pressure change pre- and post-bed rest, and optical coherence

    There is no comprehensive data or studies relating to clinical presentation and prognosis of cerebral malaria (CM) in the tribal settlements of Assam. High rates of transmission and deaths from complicated malaria guided us to conduct a prospective observational cohort study to evaluate the factors associated with poor outcome and prognosis in patients of CM. We admitted 112 patients to the Bandarpara and Damodarpur Tribal Health Centers (THCs) between 2011 and 2013 with a strict diagnosis of CM. We assessed the role of clinical, fundoscopy and laboratory findings (mainly lactic acid) in the immediate outcome in terms of death and recovery, duration of hospitalization, neurocognitive impairment, cranial nerve palsies and focal neurological deficit. The case fatality rate of CM was 33.03% and the prevalence of residual neurological sequelae at discharge was 16.07%. These are significantly higher than the previous studies. The mortality rate and neurological complications rate in patients with retinal whitening was 38.46% and 23.07%, with vessel changes was 25% and 18.75%, with retinal hemorrhage was 55.55% and 11.11% and with hyperlactatemia was 53.85% and 18.46%, respectively. Three patients of papilledema alone died. Our study suggests a strong correlation between hyperlactatemia, retinal changes (whitening, vessel changes and hemorrhage) and depth and duration of coma with longer duration of hospitalization, increased mortality, neurological sequelae and death. Plasmodium vivax mono-infection as a cause of CM has been confirmed. Prognostic evaluation of CM is useful for judicious allocation of resources in the THC.

    Prognosis of cerebral venous sinus thrombosis (CVST) has never been studied in Thailand. A simple prognostic score to predict poor prognosis of CVST has also never been reported. The authors are aiming to establish a simple and reliable prognostic score for this condition. The medical records of CVST patients from eight neurological training centers in Thailand who received between April 1993 and September 2005 were reviewed as part of this retrospective study. Clinical features included headache, seizure, stroke risk factors, Glasgow coma scale (GCS), blood pressure on arrival, papilledema, hemiparesis, meningeal irritation sign, location of occluded venous sinuses, hemorrhagic infarction, cerebrospinal fluid opening pressure, treatment options, length of stay, and other complications were analyzed to determine the outcome using modified Rankin scale (mRS). Poor prognosis (defined as mRS of 3-6) was determined on the discharge date. One hundred ninety four patients' records, 127 females (65.5%) and mean age of 36.6 +/- 14.4 years, were analyzed Fifty-one patients (26.3%) were in the poor outcome group (mRS 3-6). Overall mortality was 8.4%. Univariate analysis and then multivariate analysis using SPSS version 11.5 revealed only four statistically significant predictors influencing outcome of CVST They were underlying malignancy, low GCS, presence of hemorrhagic infarction (for poor outcome), and involvement of lateral sinus (for good outcome). Thai venous stroke prognostic score (TV-SPSS) was derived from these four factors using a multiple logistic model. A simple and pragmatic prognostic score for CVST outcome has been developed with high sensitivity (93%), yet low specificity (33%). The next study should focus on the validation of this score in other prospective populations.

    To date six long duration astronauts have experienced in flight visual changes and post flight signs of optic disc edema, globe flattening, choroidal folds, hyperoptic shifts and or raised intracranial pressure. In some cases the changes were transient while in others they are persistent with varying degrees of visual impairment. Given that all astronauts exposed to microgravity experience a cephalad fluid shift, and that both symptomatic and asymptomatic patients have exhibited optic nerve sheath edema on MRI, there is a high probability that all astronauts develop in-flight idiopathic intracranial hypertension to some degree. Those who are susceptible, have an increased likelihood of developing treatment resistant papilledema resulting in visual impairment and possible long-term vision loss. Such an acquired disability would have a profound mission impact and would be detrimental to the long term health of the astronaut. The visual impairment and increased intracranial pressure phenomenon appears to have multiple contributing factors. Consequently, the working "physiological fault bush" with elevated intracranial pressure at its center, is divided into ocular effects, and CNS and other effects. Some of these variables have been documented and or measured through operational data gathering, while others are unknown, undocumented and or hypothetical. Both the complexity of the problem and the urgency to find a solution require that a unique, non-traditional research model be employed such as the Accelerated Research Collaboration(TM) (ARC) model that has been pioneered by the Myelin Repair Foundation. In the ARC model a single entity facilitates and manages all aspects of the basic, translational, and clinical research, providing expert oversight for both scientific and managerial efforts. The result is a comprehensive research plan executed by a multidisciplinary team and the elimination of stove-piped research. The ARC model emphasizes efficient and effective

    2010-01-01

    Full Text Available Abstract Introduction Unilateral optic neuropathy is commonly due to a prechiasmatic affliction of the anterior visual pathway, while losses in visual hemifields result from the damage to brain hemispheres. Here we report the unusual case of a patient who suffered from acute optic neuropathy following hemispherical subdural hematoma. Although confirmed up to now only through necropsy studies, our case strongly suggests a local, microcirculatory deficit identified through magnetic resonance imaging in vivo. Case presentation A 70-year-old Caucasian German who developed a massive left hemispheric subdural hematoma under oral anticoagulation presented with acute, severe visual impairment on his left eye, which was noticed after surgical decompression. Neurologic and ophthalmologic examinations indicated sinistral optic neuropathy with visual acuity reduced nearly to amaurosis. Ocular pathology such as vitreous body hemorrhage, papilledema, and central retinal artery occlusion were excluded. An orbital lesion was ruled out by means of orbital magnetic resonance imaging. However, cerebral diffusion-weighted imaging and T2 maps of magnetic resonance imaging revealed a circumscribed ischemic lesion within the edematous, slightly herniated temporomesial lobe within the immediate vicinity of the affected optic nerve. Thus, the clinical course and morphologic magnetic resonance imaging findings suggest the occurrence of pressure-induced posterior ischemic optic neuropathy due to microcirculatory compromise. Conclusion Although lesions of the second cranial nerve following subdural hematoma have been reported individually, their pathogenesis was preferentially proposed from autopsy studies. Here we discuss a dual, pressure-induced and secondarily ischemic pathomechanism on the base of in vivo magnetic resonance imaging diagnostics which may remain unconsidered by computed tomography.

    Full Text Available Background: Olfactory groove schwannomas (OGS are rare anterior cranial fossa base tumors with only 41 cases reported in literature. Olfactory ensheathing cell schwannoma (OECS has similar clinico-radiological features as OGS, but a different cell of origin. In recent years, there is growing interest in OECS as more cases are being reported. Aims: The objective was to study the clinico-radiological features of OGS and define the histological differentiation from OECS. Materials and Methods: We retrospectively analyzed clinical, radiological, surgical and histopathological picture of all cases of OGS managed in our institute. Immuno histochemical studies were performed in these tumors for differentiating from OECS. A comprehensive review of articles published until date describing the operative treatment was done. Results: All three cases had presented with seizures, two had anosmia and papilledema. Gross-total resection was achieved in all our patients. One patient expired in the postoperative period due to septicemia. Positive expression to newer immuno histochemical biomarker CD57 (Leu7, with negative staining to smooth muscle α-actin (SMA was helpful in confirming the diagnosis of OGS and differentiating it from OECS in all our cases. Conclusions: OECS, though rare has to be differentiated from OGS using immuno histochemistry. Gross-total resection of OGS with preservation of olfactory function is often possible and curative. Although these tumors are commonly treated with microsurgical skull base approaches, an endoscopic endonasal approach can be considered in some cases, with repair using mucoperiosteal pedicled flap to prevent cerebrospinal fluid leak.

  14. Increased Intracranial Pressure and Visual Impairment Associated with Long-Duration Spaceflight

    Although humans have been flying in space since the 1960s, more recent missions have revealed a new suite of physiological adaptations and consequences of space flight. Notably, 60% of long-duration crewmembers (ISS/MIR) and >25% of short-duration (Shuttle) crewmembers have reported subjective degradation in vision (based on debrief comments) (Gibson 2011). Decreased near-visual acuity was demonstrated in 46% of ISS/Mir and 21% of Shuttle crewmembers, resulting in a shift of up to 1-2 diopters in their refractive correction. It is likely that the recently revealed ophthalmic changes have been present since the first days of human space flight, but have been overlooked or attributed to other causations. The reported changes in vision have occurred at various time points throughout missions, with ranging degrees of visual degradation. Although some cases resolved upon return to Earth, several astronauts have not regained preflight visual acuity, indicating that the damage may be permanent. While observing these changes over the years, without other overt symptomology and with the given age range of the flying population, this has largely been attributed to an expected hyperopic shift due to aging. However, the availability of onboard analysis techniques, including visual acuity assessments, retinal imagery, and ultrasounds of the eye and optic nerve tracts, along with more detailed post-flight techniques, has led to the recent recognition of a wider syndrome. Along with vision changes, findings include flattening of the globe, swelling of the optic disc (papilledema), choroidal folds in the retina, swelling of the optic nerve sheath, and visual field defects. It is widely hypothesized that this constellation of findings may be explained by an elevation of intracranial pressure (ICP). Out of the 60% of long-duration astronauts that have reported a subjective degradation in vision, a subset (currently 10 astronauts) have developed this syndrome. The National

    Full Text Available OBJECTIVE: Optic neuritis (ON is inflammation of the optic nerve that generally leads to transient loss of vision. Unilateral optic neuritis is quite common upon first presentation in multiple sclerosis (MS patients, but it may also remain as a clinically isolated syndrome. In this study we aimed to determine what factors are associated with the development of MS in isolated ON patients. METHODS: Medical charts of patients followed-up at Istanbul University, Faculty of Medicine, Department of Neurology between 1987 and 2003 were screened for patients with isolated ON at first presentation. A cohort of 90 patients was thusly obtained. Clinical and demographic features, visual evoked potential, cerebrospinal fluid (CSF, and magnetic resonance imaging findings, and time to definitive MS according to McDonald’s criteria were recorded. RESULTS: In all, 50% of the patients developed definitive MS after 13 months (95% CI: 4.4-19.6. Two of the patients developed neuromyelitis optica during the course of their follow-up. The development of MS was significantly associated with the presence of a T2 lesion (p= 0.001, oligoclonal bands (OCBs in the CSF (p= 0.002, absence of papilledema (p= 0.027, absence of severe visual impairment (p= 0.016, and subacute (> 1 day visual impairment (p= 0.005, as per log rank testing. According to the Cox proportional hazard regression model, the presence of a T2 lesion (hazard ratio: 4.8; 95% CI: 1.5-15.4 and OCBs (hazard ratio: 3.6; 95% CI: 1.1-11.5 are strongly predictive of the progression to MS. CONCLUSION: As some previous studies have noted, the risk of developing MS after ON is significantly higher in the presence of a T2 lesion and OCBs in the CSF. We think that this should be taken into account before starting early treatment for MS. Recent studies on the pathogenesis of MS have suggested that early treatment of MS reduces neurological disability in the long term. Our results might aid patient selection for early

    To characterize the phenotype, headache-related disability, medical co-morbidities, use of symptomatic headache medications, and headache response to study interventions in the Idiopathic Intracranial Hypertension Treatment Trial (IIHTT). Patients with untreated IIH and mild vision loss enrolled in the IIHTT and randomized to acetazolamide (ACZ) and weight loss or placebo (PLB) and weight loss had prospective assessment of headache disability using the Headache Impact Test-6 (HIT-6) questionnaire. Subjects with headache at the baseline visit were assigned a headache phenotype using the International Classification for Headache Disorders version 3 beta (ICHD-3b). Medication overuse was determined using the participants' reported medication use for the preceding month and ICHD-3b thresholds for diagnosing medication overuse headache. We investigated relationships between headache disability and various other clinical characteristics at baseline and at 6 months. Headache was present in 139 (84%) of the 165 enrollees at baseline. The most common headache phenotypes were migraine (52%), tension-type headache (22%), probable migraine (16%), and probable tension-type headache (4%). Fifty-one (37%) participants overused symptomatic medications at baseline, most frequently simple analgesics. A similar amount of improvement in the adjusted mean (± standard error) HIT-6 score occurred in the ACZ (-9.56 ± 1.05) and PLB groups (-9.11 ± 1.14) at 6 months (group difference -0.45, 95% CI -3.50 to 2.60, P = .77). Headache disability did not correlate with any of the studies, variables of interest, which included: the lumbar puncture opening pressure at baseline or at 6 months, body mass index, the amount of weight lost, papilledema grade, perimetric mean deviation, or the use of hormonal contraception. Headache disability was significantly associated with patient-reported quality of life in the physical, mental, and visual domains. Headache was common, of varied

    Full Text Available Alterações oftálmicas foram experimentalmente induzidas em caprinos após superdosagem com o anti-helmíntico closantel. Foram usados cinco caprinos com sete a oito meses de idade, produtos do cruzamento da raça Saanen com a Pardo Alpino. Os animais mostraram sinais de intoxicação entre quatro e cinco dias após a administração do closantel. Os sinais clínicos caracterizaram-se principalmente por distúrbios neurológicos centrais e cegueira. Ao exame clínico, observaram-se midríase bilateral, perda do reflexo pupilar à luz e cegueira bilateral. À oftalmoscopia indireta, foram observadas degeneração aguda de retina e papiledema. As alterações crônicas mostravam disco óptico acinzentado, atrofia de vasos e da retina. Nos fundos tapetal e não-tapetal notavam-se áreas de despigmentação e lesões irregulares castanho-amareladas. As alterações histológicas consistiam em perda dos neurônios da camada ganglionar e das células da camada nuclear interna e externa da retina. As alterações agudas no nervo óptico e na substância branca do encéfalo foram de degeneração espongiforme. As alterações crônicas do nervo óptico caracterizavam-se por extensa necrose e infiltração de células Gitter.Ophthalmic alterations were experimentally induced after overdose with the anthelmintic closantel. Five seven to eight- months-old, Saanen x Alpine caprine were used. The animals showed clinical signs of toxicosis four to five days after the administration of closantel. Clinical signs were primarily characterized by central nervous disturbances and blindness. Clinically, bilateral mydriasis, loss of pupillary light reflex, and blindness were observed. At indirect ophthalmoscopic examination, there was acute retinal degeneration and papilledema. Chronic ocular changes consisted of paleness of the optic disc, vascular atrophy, and retinal atrophy. Areas of pigment loss and irregular yellowish-brown foci were present in the tapetal

    There is growing body of evidence that usage of computers can adversely affect the visual health. Considering the rising number of computer users in Egypt, computer-related visual symptoms might take an epidemic form. In view of that, this study was undertaken to find out the magnitude of the visual problems in computer operators and its relationship with various personal and workplace factors. Aim: To evaluate the probable effects of exposure to electromagnetic waves radiated from visual display terminals on some visual functions. Subjects and Methods: hundred fifty computer operators working in different institutes were randomly selected. They were asked to fill a pre-tested questionnaire (written in Arabic), after obtaining their verbal consent. The selected exposed subjects were were subjected to the following clinical assessment: 1-Visual acuity measurements 2-Refraction (using autorefractometer). 3- Measurements of the ocular dryness defects using the following different diagnostic tests: Schirmer test-,Fluorescein staining , Rose Bengal staining, Tear Break Up Time (TBUT) and LIPCOF test (lid parallel conjunctival fold). A control group included hundred fifty participants, they are working in a field does not necessitate exposure to video display terminals. Inclusion criteria of the subjects were as follows: minimum three symptoms of computer vision syndrome (CVS), minimum one year exposure to (VDT, s) and minimum 6 hs/day in 5working days/week. Exclusion criteria included candidates having ocular pathology like: glaucoma, optic atrophy, diabetic retinopathy, papilledema The following complaints were studied: 1-Tired eyes. 2- Burning eyes with excessive tear production. 3-Dry sore eyes 4-Blurred near vision (letters on the screen run together). 5-Asthenopia. 6-Neck, shoulder and back aches, overall bodily fatigue or tiredness. An interventional protective measure for the selected subjects from the exposed group was administered, it included the following (1

    To characterize shifts from the 1960s to the first decade in the 21st century as to diagnostics, case-mix, and surgical management of pediatric patients undergoing permanent CSF diversion procedures. One hundred and thirty-four patients below 15 years of age were the first time treated with CSF shunt or ETV for hydrocephalus or idiopathic intracranial hypertension (IIH) in 2009-2013. This represents our current practice. Our previously reported cohorts of shunted children 1967-1970 (n = 128) and 1985-1988 (n = 138) served as backgrounds for comparison. In the 1960s, ventriculography and head circumference measurements were the main diagnostic tools; ventriculoatrial shunt was the preferred procedure (94 %), neural tube defect (NTD) was the leading etiology (33 %), and overall 2-year survival rate was 76 % (non-tumor survival 84 %). In the 1980s, computerized tomography (CT) was the preferred diagnostic imaging tool; ventriculoperitoneal shunt (VPS) had become standard (91 %), the proportion of NTD children declined to 17 %, and the 2-year survival rate was 91 % (non-tumor survival 95 %). Hydrocephalus caused by intracranial hemorrhage had, on the other hand, increased from 7 to 19 %. In the years 2009-2013, when MRI and endoscopic third ventriculocisternostomy (ETV) were matured technologies, 73 % underwent VPS, and 23 % ETV as their initial surgical procedure. The most prevalent etiology was CNS tumor (31 %). The proportion of NTD patients was yet again halved to 8 %, while intracranial hemorrhage was also reduced to 12 %. In this last period, six children were treated with VPS for Idiopathic Intracranial Hypertension (IIH) due to unsatisfactory response to medical treatment. They all had headache, papilledema, and visual disturbances and responded favorably to treatment. The 2 years of survival was 92 % (non-tumor survival 99 %). In contrast to the previous periods, there was no early shunt related mortality (2 years). Aqueductal stenosis

    papilledema, peripapillary exsudate and tapetum pigmentation were noted in three dogs submitted to retinograph. The histopathology showed focal mononuclear infiltrate of choroid, congestion of chorioretinal vessels an subretinal edema in eight dogs. Our results allow to conclude that acquired ocular toxoplasmosis in the dogs is as significant as in man and in doing so other studies must be undertaken.

    interval between onset of symptoms and diagnosis of infection was greater in Group II (53 days than in Groups I (25 days or III (28 days. Neck stiffness, cranial nerve involvement and papilledema were more frequent in Group I than in Group II or III, but fever and focal neurological signs were observed only in patients of two last groups. Cerebrospinal fluid examination showed a mild lymphocytic pleocytosis in most patients, but transplant cases had polymorphonuclear cells more frequently. Late mortality was higher in patients with underlying disease and the prognosis was better for transplant patients that received effective antifungal therapy. Besides cryptococci, autopsy findings in 8 cases revealed granuloma formation in tissues, except in patients of Group II (2 cases. The differences between the groups suggest that clinical characteristics, evolution and postmortem findings of the cryptococcal meningitis are changed according to type of immunodeficiency presented by the patient.

    -phase neurotoxoplasmosis. METHODS: A prospective study of case series type was developed, including 70 patients of both sexes and ages ranging from 20 to 63 years who were admitted to the wards of three public hospitals in the city of Recife, Pernambuco, Brazil, from January to October 2008, with diagnoses of AIDS and neurotoxoplasmosis determined according to the criteria of the Centers for Disease Control and Prevention (1992. The patients were characterized by a first episode of neurotoxoplasmosis (65; 92.9% or recurrence (5; 7.1%, unawareness of having AIDS (23; 32.9%, mean T CD4+ count of 139.8 ± 3.04 lymphocytes/mm³ and mean viral load of 137,080 ± 39,380 copies/ml. All patients underwent ophthalmological examination consisting of ocular inspection, gauging of visual acuity, investigation of ocular extrinsic muscle function and fundoscopy using a binocular indirect ophthalmoscope (model OHM 3.5 Eyetec® and external lens of 20 diopters (Volk®. RESULTS: The findings consisted of retinal cotton-wool spot exudates (8.6%, slight diffuse arteriolar constriction (8.6%, retinochoroiditis scars characteristic of ocular toxoplasmosis (5.7%, atrophy of retinal pigment epithelium (2.9%, retinal detachment (2.9%, increased papillary excavation (1.4%, retinal peripheral degeneration (1,4%, macroaneurysm (1.4%, bilateral papilledema (1.4% and vitreous-retinal traction (1.4%. CONCLUSIONS: Patients with AIDS and neurotoxoplasmosis may present fundoscopic abnormalities characteristic of ocular toxoplasmosis, either in active or in scar form, related to HIV or even to other opportunist or systemic diseases, which can be of great aid for integral treatment of patients by a multiprofessional team.
