Marcus D Mazur, Richard Gurgel, Joel D MacDonald
BACKGROUND AND IMPORTANCE: Dissection of cerebellopontine angle (CPA) tumors that abut or adhere to the brainstem or cranial nerves can be a challenging surgical endeavor. We describe the use of semitranslucent latex rubber pledgets in the tumor-brain interface as a method to improve visualization and protection of vital tissue during microsurgical dissection of CPA masses. The rubber pledgets are fashioned by cutting circular discs out of the cuff portion of talc-free, partially opaque latex gloves...

A case of coexistent glossopharyngeal neuralgia and hemifacial spasm was treated by transposition of the vertebral artery. A 60-year-old man was referred to our hospital due to pain in the left posterior part of the tongue that was difficult to control with oral medication at a local hospital. The diagnosis was left glossopharyngeal neuralgia based on the symptoms, imaging findings, and lidocaine test results. Moreover, the patient had left hemifacial spasm. Microvascular decompression was performed, which confirmed that the vertebral artery was compressing the lower cranial nerve and the posterior inferior cerebellar artery was compressing the root exit zone of the facial nerve...

BACKGROUND: Of the various management options for isolated fourth ventricle (IFV), fourth ventriculoperitoneal shunts (FVPS) and aqueductal stents (AST) have been the most favored. Though effective, FVPS are often difficult to place and have higher complication rates than conventional ventricular shunts. OBJECTIVE: To assess the efficacy of AST in IFV and compare the outcome with FVPS. METHODS: Twenty-five patients surgically treated for IFV were analyzed...

Rapid improvement of tick-borne encephalitis after treatment with corticosteroids Tick-borne encephalitis (TBE) is a viral disease transmitted by ticks. The virus is divided into three subtypes named Western, Siberian and Far Eastern TBE virus (TBEV). Western TBEV is endemic in parts of Europe and Sweden and typically causes a biphasic illness with influenza-like symptoms followed by neurological symptoms ranging from mild meningitis to severe meningoencephalitis and death. Despite an effective vaccine, TBE is increasing in Sweden and Europe...

REVIEW
Feyce Peralta, Sarah Devroe
Unintentional dural puncture followed by postdural puncture headache is a well-known complication following neuraxial labor analgesia. Risk factors for the development of postdural puncture headache may be related to the patient's history and characteristics, the neuraxial technique, and obstetrical events. The diagnosis of postdural puncture headache is usually made depending on the clinical presentation (orthostatic headache after a neuraxial procedure). Occasionally, neuroimaging and neurological consultation are warranted...

Cerebral venous thrombosis is a rare complication of intracranial hypotension. We describe 3 cases in which this phenomenon occurred, as a result of a lumbar puncture or due to a spontaneous cerebrospinal fluid leak. We emphasize the importance of early detection of the intracranial hypotension syndrome, the most common clinical manifestation being orthostatic headache. It is not an innocent condition as it is associated with other potential complications such as subdural hygroma/hematoma, cranial nerve palsies, cerebellar tonsillar descent, and even brainstem manifestations...

The aim of this study was to elucidate the cause of a neurological syndrome characterized by stridor in adult goats with clinical signs of copper deficiency. The main clinical signs consisted of apathy, emaciation, pale mucous membranes, mucous nasal discharge, dyspnea, severe achromotrichia, diffuse alopecia, torpor, ataxia, and stridor. When the goats were forced to move, the stridor increased. In a herd of 194 Toggenburg goats, 10 adult goats with clinical signs of copper deficiency were removed from the herd and divided into 2 groups: group 1, which consisted of 4 nannies and 1 buck with stridor, and group 2, which consisted of 4 nannies and 1 buck without stridor...

OBJECTIVE: In symptomatic unruptured intracranial aneurysms (UIA), data on long-term functional outcome are sparse in the literature, even in the light of modern interdisciplinary treatment decisions. We therefore analysed our in-house database for prognostic factors and long-term outcome of neurological symptoms after microsurgical/endovascular treatment. METHODS: Patients treated between 2000 and 2016 after interdisciplinary vascular board decision were included...

Osteogenesis imperfecta (OI) is a bone disorder that can lead to skull base deformities such as basilar invagination, which can cause compression of cranial nerves, including the trigeminal nerve. Trigeminal neuralgia in such cases remains a challenge, given distorted anatomy and deformities. We present an alternative option, consisting in cannulation of the foramen ovale and classical percutaneous treatment. Percutaneous balloon microcompression was performed in a 28 year-old woman with OI and severe trigeminal neuralgia using computed tomography (CT) and radiographic-guided cannulation of the Gasserian ganglion without neuronavigation or stereotactic devices...

Antlers are the cranial appendages of deer that regenerate each year. This renewal provides a model to explore molecules involved in mammalian organ regeneration. The cellular distributions of the brain-derived neurotrophic factor (BDNF) and the isoforms of its cognate receptor Trk tyrosine kinase receptor (TrkB) were localized by immunohistochemistry in sections of growing red deer antler. BDNF and TrkB full length were widely expressed in the integument, perichondrium, periosteum and bone. The truncated isoform receptor was particularly evidenced in integument and vascular inner dermis, but very light reaction was observed in cartilage and bone, both at the site of endochondral and intramembranous ossification...

Central skull base osteomyelitis is a rare, but potentially life-threatening disease entity often lacking otologic symptoms or external auditory canal pathology. We present a case of a man in his 70s who had developed cranial nerve deficits with radiographic evidence that was consistent with a tumor due to this uncommon entity. The radiologic findings and our experience are discussed to increase awareness in the otolaryngology community.
