INTRODUCTION: The combination of bilateral microphthalmos, cystic coloboma and eyelid agenesis is rare. The definite diagnosis of this malformation is established by fundoscopic examination and confirmed by imaging modalities such as ultrasonography (US) and magnetic resonance imaging (MRI). This disorder may be associated with specific chromosomal abnormalities. CASE REPORT: A 1-week-old male newborn was referred for bilateral eyelid agenesis. He was born at term by caesarean for foetal distress, after an uneventful gestation...

Evidence supporting the hypothesis that reduced cerebrospinal fluid (CSF) clearance is involved in the pathophysiology of Alzheimer's disease (AD) comes from primarily from rodent models. However, unlike rodents where predominant extra-cranial CSF egress is via olfactory nerves traversing the cribriform plate, human CSF clearance pathways are not well characterized. Using dynamic Positron Emission Tomography (PET) with (18)F-THK5117 a tracer for tau pathology, the ventricular CSF time activity was used as a biomarker for CSF clearance...

BACKGROUND AND PURPOSE: The trochlear groove and trochlear cistern are anatomic landmarks closely associated with the tentorial segment of cranial nerve IV. The purposes of this study were to describe the MR imaging appearances of the trochlear groove and trochlear cistern and to test our hypothesis that knowledge of these anatomic landmarks facilitates identification of cranial nerve IV in routine clinical practice. MATERIALS AND METHODS: For this retrospective study, consecutive MR imaging examinations of the sinuses performed in 25 patients (50 sides) at our institution were reviewed...

Aponeurotic ptosis accounts for the majority of acquired ptosis encountered in clinical practice. Other types of ptosis include traumatic, mechanical, neurogenic, and myogenic. In addition to true ptosis, some patients present with pseudoptosis caused by globe dystopia, globe asymmetry, ocular misalignment, or retraction of the contralateral lid. It is particularly important for the clinician to rule out neurologic causes of ptosis such as dysfunction of the third cranial nerve, Horner's syndrome, and myasthenia gravis, as these conditions can be associated with significant systemic morbidity and mortality...

INTRODUCTION: glomus tumours of the temporal bones rank second after neurinomas of the VII-th pair of cranial nerves among the pathological conditions that are likely to cause hearing mpairment. Being extensively vascularized locally invasive neoplasms, glomus tumours constitute a serious challenge for the surgeon because of their localization in the vicinity of the vitally important vascular and neural structures of the lateral skull base. AIM: To characterize some peculiar features of the surgical interventions and postoperative management of the patients presenting with different types of glomus tumours...

Isolated unilateral abducens nerve palsy is usually due to ischemia, trauma or neoplasm. Dorello's canal is the space between the petrous apex and superolateral portion of the clivus, bound superiorly by Gruber's ligament. The abducens nerve travels with inferior petrosal sinus (IPS) though the Dorello's canal before entering the cavernous sinus. A 31-year-old man presented with neck pain, and binocular horizontal diplopia, worse looking towards left and at distance. He had a history of intravenous drug abuse but no history of hypertension or diabetes...

INTRODUCTION: There are various communications between the superior cervical ganglion (SCG) and the vagus and glossopharyngeal nerves. However, little information exists concerning the origin of these sympathetic ganglion branches at the superior, middle, and inferior regions of the human SCG. The aim of this study was to describe the human SCG in a morphometric manner with the communication with cranial and cervical nerves and supply. METHODS: This study characterized 72 SCG samples from 54 elderly Japanese human cadavers (30 males, 24 females; 65-100 years old)...

BACKGROUND: Charcot-Marie-Tooth disease (CMT) type 1A is the most common form of CMT 1 and one of the autosomal dominant demyelinating hereditary motor and sensory neuropathies (HMSN). Cranial nerves may be frequently subclinically affected in CMT disease. However manifest clinical signs of cranial nerve involvement are rare. METHODS: This case comprise neurological, ophthalmological, internal medicine and ear-nose-throat investigation, motor and sensory nerve conduction velocity, auditory evoked potentials and orbicularis-oculi reflex measurements, lumbar puncture and blood examination, inclusive molecular genetic testing, as well as electrocardiogram and cranial imaging such as computer tomography and magnetic resonance imaging RESULTS: The present case shows a Charcot-Marie-Tooth (CMT) 1A patient with complete unilateral oculomotor palsy in combination with predominant ipsilateral subclinical trigeminal demyelination...

Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a 47-year-old female who presented to the emergency department with acute severe headache and nausea/vomiting. On MRI examination acute hydrocephaly due to hemorrhagic colloid cyst was detected...

Multiple sclerosis (MS) is a chronic disorder that affects the central nervous system myelin. However, a few radiological cases have documented an involvement of peripheral cranial nerves, within the subarachnoid space, in MS patients. We report the case of a 36-year-old female with a history of relapsing-remitting (RR) MS who consulted for a subacute complete paralysis of the right III nerve. Magnetic resonance imaging (MRI) examination showed enhancement and thickening of the cisternal right III nerve, in continuity with a linear, mesencephalic, acute demyelinating lesion...

Electromagnetic stimulation applied at the cranial level, i.e. transcranial magnetic stimulation (TMS), is a technique for stimulation and neuromodulation used for diagnostic and therapeutic applications in clinical and research settings. Although recordings of TMS elicited motor-evoked potentials (MEP) are an essential diagnostic tool for spinal cord injured (SCI) patients, they are reliably recorded from arm, and not leg muscles. Mid-thoracic contusion is a common SCI that results in locomotor impairments predominantly in legs...

The vagus nerve (VN) is the longest cranial nerve, innervating the neck, thorax and abdomen, with afferent fibers transmitting a range of interoceptive stimuli and efferent fibres to somatic structures and autonomic preganglions. Over the last few decades, electrical stimulation of the VN using implanted devices (VNS) has been developed leading to its approval for the treatment of epilepsy and depression. More recently, non-invasive devices to stimulation the VN have been developed. The VN has many functions and the activity that is most amenable to assessment is its effect in controlling the cardiac rhythm...
