Visual Blurring

An 46-year-old Caucasian woman was diagnosed with idiopathic intracranial hypertension (IIH) after presenting with papilledema and bilateral visual blurring. Lumbar puncture revealed an opening pressure of more than 550 mmH2O. Cerebral magnetic resonance imaging (MRI) showed bilateral flattening of the posterior sclera, enhancement of the prelaminar optic nerve, distension of the perioptic subarachnoid space, intraocular protrusion of the prelaminar optic nerve and empty sella. The main purpose of the treatment was to release the symptoms and preserve the vision. It was initiated the general treatment with Mannitol 20%, 250 ml/day, Acetazolamide 2x500 mg/day and B-vitamins. After discharge the patient followed a treatment with acetazolamide 2x250 mg/ daily doses and oral potassium supplements 30 mg bid/day.

Magnetic resonance imaging (MRI) signs of elevated intracranial pressure and idiopathic intracranial hypertension have been well characterized in adults but not in children. The MRIs of 50 children with idiopathic intracranial hypertension and 46 adults with idiopathic intracranial hypertension were reviewed for optic nerve head protrusion, optic nerve head enhancement, posterior scleral flattening, increased perioptic cerebrospinal fluid, optic nerve tortuosity, empty or partially empty sella, tonsillar herniation, enlargement of Meckel’s cave meningoceles, and transverse venous sinus stenosis(TSS). Compared to adolescents (11-17 years, n = 40) and adults (>17 years, n = 46), prepubescent children (<11 years, n = 10) had lower frequencies of scleral flattening (50% vs 89% and 85%, P = .02), increased perioptic cerebrospinal fluid (60% vs 84% and 89%, P = .08), optic nerve tortuosity (20% vs 46% and 59%, P = .07), empty or partially empty sella (56% vs 78% and 93%, P = .007), and TSS (67% vs 93% and 96%, P = .04). Children with idiopathic intracranial hypertension have similar MRI findings as adults, but they are less frequent in prepubescent children.

Background The primary role of neuroimaging in idiopathic intracranial hypertension (IIH) is to exclude secondary causes of raised intracranial pressure. Recently, a few imaging markers have been described which may suggest diagnosis of IIH in atypical cases. We carried out this study to assess the prevalence and accuracy of these neuroimaging signs in predicting the diagnosis of IIH. Methods Eighty treatment-naive patients with IIH and 30 controls were recruited as per a predefined criterion. Magnetic resonance imaging (MRI) brain with detailed sella imaging was done in all patients. Results The most common abnormality noted was optic nerve tortuosity in 82.5% of patients, followed by posterior scleral flattening in 80%, perioptic subarachnoid space (SAS) dilatation in 73.8% and partial empty sella in 68.8% of patients. The presence of optic nerve tortuosity was the most sensitive sign on neuroimaging, though the highest specificity was seen for posterior scleral flattening and perioptic SAS dilatation. The presence of more than three neuroimaging features correlated with severity of vision loss. Conclusion In suggestive clinical scenarios, posterior scleral flattening, perioptic SAS dilatation and optic nerve tortuosity are highly sensitive and specific signs in IIH. This study also highlights the utility of MRI as a valuable tool for prognosis of visual outcome in patients with IIH.

The Brain

Background: Familial idiopathic intracranial hypertension (FIIH) is a rare condition, the etiology of which is unclear.Aims: To describe two non-obese Chinese sisters who met the criteria of FIIH and to analyze the clinical features and prognosis of FIIH.Methods: The clinical course, treatment, and prognosis of these two patients were analyzed retrospectively. Meanwhile, all the literature of familial IIH (FIIH) was reviewed.Results: These two sisters presented with headaches and visual impairment in their mid-thirties. Magnetic resonance imaging (MRI) of the brain was unremarkable except for partial empty sella. No comorbidities or defined causes were detected. Headaches were partially relieved by dehydrated medicine, whereas the visual impairment persisted.Conclusion: In cases where patients present with headaches, empty sella are found on an MRI, and there is visual impairment with or without papilla edema, intracranial hypertension should be excluded. Furthermore, we should pay more attention to the relatives of those patients with increased intracranial hypertension.

Meningiomas are known to be more common in females than males. They are also known in rare cases to grow in size during pregnancy, which can complicate its management. We describe a 31-year-old Caucasian woman who presented with blurring of her vision and diplopia during the third trimester of her pregnancy. Magnetic resonance imaging (MRI) showed a small left cavernous sinus meningioma. The patient was treated conservatively until her uncomplicated delivery. A postpartum MRI scan showed complete regression of the suspected meningioma. Currently the patient is contemplating a further pregnancy.

Orbital Pain

Magnetic resonance imaging disclosed both optic nerve tortuosity and kinking in a 64-year-old man with orbital pain and monolateral abducens nerve palsy. The association between optic nerve tortuosity and abducens nerve palsy is often described in literature reports of idiopathic intracranial hypertension. However the diagnosis of idiopathic intracranial hypertension was excluded in our patient because of the absence of other signs such as papilledema (universally present in the cases of idiopathic intracranial hypertension), visual loss, headache and flattening of the posterior sclera. Other possible diagnoses to be considered when looking at a case of optic nerve tortuosity are neurofibromatosis and/or optic nerve glioma. Tortuosity of both optic nerves seems to be isolated in our patient and not associated with other diseases or disorders. We suggest that in some patients optic nerve tortuosity could be correlated with an aberrant anatomical development of the optic nerve. Further studies are necessary to confirm this hypothesis which currently remains conjectural.

Background: Much congenital and intracranial pathology may affect optic nerve (ON) and caused increased or decreased in size, so the measurement is crucial and aiding in diagnosed of some neurogenic and endocrine disorders. The aim of this study was to measure the normal ON length and diameter by magnetic resonance imaging among pediatric at Khartoum state Sudan.Methods: This was descriptive, cross section study,  done in 100 Sudanese pediatrics with age from 1 month to 15 years came to Magnetic resonance imaging (MRI) department for MRI brain at three hospitals in Khartoum state  (Al-Amal national hospital, Al-Zaitona hospital and Modern Medical Center) during the period from December 2019 to March 2020, all of patients had no pathological or medical condition that may affect the orbits and optic nerve (OON), any child with and medical condition or pathology related to orbits excluded from study sampling. The data were collected by data collection sheet designed especially for this study then analyzed.Results: The study found that the mean diameter of ON was 2.06±0.44 mm, the mean length of right ON was 31.54±4.11 mm, there is no significant different in measurement between males and females (p>0.05), there was strong significant correlation between ON length and diameter with children age (r=0.592**, 0.654**, p<0.001 respectively).Conclusions: The study concluded that there was strong correlation between right and left ON diameter and length with age.

The diagnosis and management of intraorbital foreign bodies are challenging for surgeons. Foreign bodies made of wood and those located close to the optic nerve are especially difficult to manage. Herein, we report our experience with the diagnosis and management of intraorbital wooden foreign bodies utilizing magnetic resonance imaging (MRI). A 50-year-old man presented to the emergency room with a laceration on his left upper eyelid. No foreign bodies were visible through the laceration, and computed tomography findings showed only evidence of cellulitis with abscess formation. Despite drainage and antibiotics, the cellulitis worsened; subsequently, we found multiple wooden foreign bodies on MRI. Surgical removal was performed, excluding those in the intraconal space to avoid optic nerve damage. The patient recovered well and has not experienced any ophthalmic complications at 1 year of follow-up.
