Kailash Chandra Patra, Abhijeet Prakash Kirtane
The Arnold-Chiari Type 1 malformation (CM1) is a rare congenital abnormality characterized by ectopia or caudal herniation of the cerebellar tonsils through the foramen magnum into the cervical spine, resulting in crowding at the craniocervical junction. It seldom presents in childhood with symptoms and a normal neurological examination. More typically, CM1 presents in young adult women with neurological symptoms including a headache, cervical pain, cranial nerve palsies, neurosensory deficit, and ataxia. Ocular manifestations associated with Chiari I include third and sixth cranial nerve paresis and convergence/divergence abnormalities...

An aneurysm of the distal superior cerebellar artery (SCA) is a highly rare disease. Fusiform aneurysms of the distal SCA are particularly challenging to treat. Clipping, trapping with or without bypass using microsurgery or endovascular treatment (EVT) were used to treat this condition. We describe the case of fusiform distal SCA aneurysms treated successfully with endovascular coiling with a 3-month follow-up. A 39 year-old male was presented with subarachnoid hemorrhage (SAH) and a 15 mm fusiform aneurysm of the ambient segment of the left distal SCA...

Ocular motor palsy is a rare but alarming complication of subarachnoid puncture. In order to better understand this condition, a literature search was performed in English of PubMed articles for cranial nerves III, IV, and VI palsies after spinal puncture. Sixty-five articles (dated 1930-2015) were identified, and 114 cases were obtained for analysis. Subarachnoid anesthesia was the most frequent cause (45.6%), with a higher incidence for females than males. The age of patients was 40.24 ± 13.35 years (age range, 6-71 years)...

BACKGROUND AND PURPOSE: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is an immune-mediated chorioretinal disease that causes acute visual symptoms with characteristic ophthalmoscopic findings. Neurological complications are rarely reported in the literature. Here we report two new cases of APMPPE that presented with neurological manifestations, one of which was associated with peripheral neuropathy, which has not been described before. METHODS: A retrospective database review of all patients with a diagnosis of APMPPE was performed...

Zhiliang Yang, Guilian Sun
BACKGROUND: Sixth (abducens) nerve palsy (ANP) is far less frequent in children and has not been reported as a sign of acute disseminated encephalomyelitis (ADEM). We present an infant case of ADEM with bilateral abducens nerve palsy (BANP). CASE PRESENTATION: We report one case of BANP in a 15-month-old boy of fulminant ADEM. The patient underwent physical examinations and brain MRI scan three times during about six months follow-up. The patient had BANP and developmental regression when he regained consciousness from a coma, and the signs had persisted for 6-months...

Bell's palsy is the most common cause of acute peripheral facial nerve paralysis, but the optimal dose of corticosteroids in pediatric patients is still unclear. This retrospective study aimed to evaluate the efficacy of low-dose corticosteroid therapy compared with high-dose corticosteroid therapy in children with Bell's palsy. Patients were divided into 2 groups based on the dose of oral prednisolone regimen initiated. The severity of idiopathic facial nerve paralysis was graded according to the House-Brackmann Grading Scale...

BACKGROUND: Botulinum toxin A (BTX) has been widely used for a variety of facial esthetic procedures within the last couple of decades. Efficacy and safety of BTX for facial rejuvenation has been extensively studied in multiple randomized prospective controlled trials. Focal weakness is among the most commonly reported adverse effects. Adverse reactions tend to occur most commonly due to errors in dosing formulation and errors with the techniques of the application. No serious long-term complications have been reported...

BACKGROUND: Neurotoxicity is a common side effect of treatment with calcineurin inhibitors. Tremors are frequently reported as the most common manifestation. Variable presentations can include headaches, seizures, visual hallucinations or blindness. Sixth nerve palsy has been reported in previous cases of bone marrow and cardiac transplant patients receiving calcineurin inhibitors. In many of these previously reported cases, the drug was administered intravenously and very high drug levels were found...

BACKGROUND: Pituitary apoplexy (PA) often presents with acute headache and neuro-ophthalmic manifestations, including ocular motility dysfunction (OMD) from cranial nerve palsies (CNPs). Our goal was to describe the epidemiology and outcomes of OMD in a large, single-center series of patients with PA. METHODS: We conducted a retrospective chart review of all patients with PA seen in our pituitary center between January 1995 and December 2012. Presenting neuro-ophthalmic, endocrine, and radiologic data, as well as neuro-ophthalmology follow-up data, were collected...

Botulinum toxin can be a useful tool for treating acute sixth nerve palsy and excessive eye deviations due to unstable Graves' disease, when surgery is not yet possible. The diagnostic injection for estimation of possible postoperative double vision also makes sense. In convergence spasms, periocular botulinum toxin injections can be a therapeutic option. Botulinum toxin is not a first line option in infantile esotropia without binocularity or in adult horizontal strabismus. Side effects include ptosis and vertical deviations...

BACKGROUND: Facial nerve palsy (FNP) occurs less frequently in children as compared to adults but most cases are secondary to an identifiable cause. These children may have a variety of ocular and systemic features associated with the palsy and need detailed ophthalmic and systemic evaluation. METHODS: This was a retrospective chart review of all the cases of FNP below the age of 16 years, presenting to a tertiary ophthalmic hospital over the period of 9 years, from January 2000 to December 2008...

Traumatic brain injury (TBI) is less common in children than in adults. Posterior fossa lesions are even more uncommon, but, when present, are usually epidural hematomas. These lesions, even when small, may have a bad outcome because of the possibility of compression of the important structures that the infratentorial compartment contains, such as the brainstem and cranial nerves, and the constriction of the fourth ventricle, causing acute hydrocephalus. Although unusual, posterior fossa lesions are increasingly being diagnosed because of the better quality of and easier access to cranial tomography...

Alberto Gálvez-Ruiz, Patrik Schatz
BACKGROUND: Vascular risk factors are increasing rapidly in the Middle East. Growing inactivity and obesity have contributed to an epidemic of Type 2 diabetes mellitus (DM) in the Arab population. Microvascular palsies of the third, fourth, and sixth cranial nerves, which occur in an isolated manner, are relatively common in patients with DM, hypertension, or other vascular risk factors. METHODS: In this retrospective analysis, patients with diabetes with microvascular palsies were assessed for the prevalence of diabetic retinopathy (DR)...

The emissary veins, like the petrosquamosal sinus (PSS), are residual valveless veins, which connect the intracranial dural venous sinuses and the extracranial venous system. Rarely, they may cause pulsatile tinnitus (PT). A 22-year-old woman developed in the first week of puerperium worsening headaches, vomiting, and diplopia, and the accentuation of a PT in the left ear that she presented for eight years. The clinical examination findings nine days after delivery were unremarkable, with the exception of a left sixth nerve palsy, and a peculiar sensibility of the left temporo-mandibular joint...

BACKGROUND/PURPOSE: There are no concrete guidelines for the therapeutic use of botulinum toxin in strabismus. The 2012 Cochrane Analysis concluded that it was controversial, but included only 4 prospective randomized controlled trials. However, many retrospective studies suggest that botulinum toxin treatment is a viable alternative to surgical treatment. We have now retrospectively evaluated the outcomes of our patients treated with botulinum toxin. PATIENTS AND METHODS: We retrospectively reviewed the charts of the patients treated with Botox® for strabismus...
