A 59-year-old man developed a sudden onset of vertigo and nausea, and after a few hours, he could not swallow at all. On admission, neurological examination revealed severe dysphagia associated with other transient and mild neurological deficits, including left facial paresis, and hypesthesia in the right side of his body. MRI with diffusion weighted imaging showed a hyperintense signal lesion at the left rostral medial region of the medulla, prompting the diagnosis of an acute medial medullary infarction. His facial paresis and hypesthesia disappeared within 2 weeks...

The reduction in intraoral pressure during swallowing has previously been linked to bolus transport, although no such relation has yet been proven. The purpose of this work was to evaluate the time course of intraoral pressure during swallowing using simultaneous real-time magnetic resonance imaging (MRI) and dynamic pressure recordings. Real-time MRI based on highly undersampled radial fast low-angle shot (FLASH) and regularized nonlinear inverse reconstruction was performed at 3 T using a standard head coil and a mid-sagittal section covering the entire oral cavity...

OBJECTIVES: Aspiration after stroke has been associated with aspiration pneumonia, which contributes to increased mortality of stroke. Laryngeal elevation is a core mechanism for protection from aspiration. Few studies have explored the predictive value of laryngeal elevation velocity for aspiration after stroke. This study aimed to explore the ability of laryngeal elevation velocity to predict aspiration in patients with acute ischemic stroke. METHODS: This was a prospective cohort study that included consecutive acute ischemic stroke patients treated at a teaching hospital during a 10-month period...

BACKGROUND: Previous case-control studies have suggested that the absence of a swallow-tail appearance in the substantia nigra on high-resolution SWI, representing nigrosome-1, has high accuracy to identify Parkinson's disease (PD). The first goal of our study was to evaluate nigrosome-1 ex vivo using optimized high-resolution susceptibility sensitive MRI. Our second goal was to evaluate its diagnostic value in vivo using a clinical 3T SWI sequence to differentiate between PD and atypical parkinsonism (AP) in a cohort of patients with early-stage parkinsonism...

The goal of tongue microvascular reconstruction is to maximise oral function with less morbidity while preserving speech and swallowing. This kind of reconstruction often requires a bigger flap volume than is actually needed to repair the defect. This is because every reconstructive flap is subject to a shrinking process due to oedema reduction and differences among individual tissue healing processes. Moreover, patients with advanced cancers often need adjuvant radiation therapy, which can result in further flap volume loss...

INTRODUCTION: Liposarcoma is a rare malignant mesenchymal tumour. Very few cases of retropharyngeal liposarcoma have been reported in the literature. SUMMARY: A 30-year-old woman with no notable history reported swallowing disorders for the past year associated with dysphonia. Nasal endoscopic examination demonstrated a tumour arising from the left lateral pharyngeal wall, ascending as far as the junction of the free margin of the epiglottis, aryepiglottic fold, and pharyngoepiglottic fold and obliterating the ipsilateral pyriform sinus with preservation of cord mobility...

BACKGROUND: Noncontiguous cervical spondylotic myelopathy (CSM) is a special degenerative disease because of the intermediate normal level or levels between supra and infraabnormal levels. Some controversy exists over the optimal procedure for two noncontiguous levels of CSM. The study was to evaluate the outcomes of the anterior cervical discectomy and fusion (ACDF) with zero-profile devices for two noncontiguous levels of CSM. MATERIALS AND METHODS: 17 consecutive patients with two noncontiguous levels of CSM operated between December 2009 and August 2012 were included in the study...

Chronic aspiration poses a major health risk to the pediatric population. We describe four cases in which work up for chronic aspiration with a brain MRI revealed a Chiari I malformation, a poorly described etiology of pediatric aspiration. All patients had at least one non-specific neurologic symptom but had swallow studies more characteristic of an anatomic than a neurologic etiology. Patients were referred to neurosurgery and underwent posterior fossa decompression with symptom improvement. A high index of suspicion for Chiari malformation should be maintained when the standard work up for aspiration is non-diagnostic, particularly when non-specific neurologic symptoms are present...

Here, we report a case of vertebral artery aneurysm causing dysphagia in a 56-year-old man who had no remarkable past history. Two months before the first visit, he developed posterior neck pain followed by difficulty swallowing 1 month later. He was referred to our clinic because of gradually worsening dysphagia. Physical examination showed paralysis of cranial nerves IX, X, and XII; therefore, he was hospitalized. Because enhanced CT and MRI showed a partially thrombosed right vertebral artery aneurysm, he was transferred to the care of the Department of Neurosurgery...

PURPOSE: For the first time, MRI-guided radiation therapy systems can acquire cine images to dynamically monitor in-treatment internal organ motion. However, the complex head and neck (H&N) structures and low-contrast/resolution of on-board cine MRI images make automatic motion tracking a very challenging task. In this study, the authors proposed an integrated model-driven method to automatically track the in-treatment motion of the H&N upper airway, a complex and highly deformable region wherein internal motion often occurs in an either voluntary or involuntary manner, from cine MRI images for the analysis of H&N motion patterns...

Several dynamic magnetic resonance imaging (MRI) techniques to observe swallowing and their parameters have been reported. Although these studies used several contrast enhancement liquids, no studies were conducted to investigate the most suitable liquids. The purpose of this study was to identify the optimal contrast enhancement liquid for dynamic MRI of swallowing. MRI was performed using a new sequence consisting of true fast imaging with steady-state precession, generalised auto-calibrating partially parallel acquisition and a keyhole imaging technique...

Ingestion of foreign bodies, common in the emergency services, remains a challenge for physicians despite preventive measures and technical progress due to the frequency and possible complications, serious complications that can darken vital prognosis or may be a source of remote morbidity. Clinical experience at "St. Mary" Hospital included, between 2000-2015, 39 patients diagnosed with FB ingestion, of which 26 fixed in the oesophagus, with the remaining 13 having spontaneously progressed along the digestive tract (5 recovered from the stomach, 6 naturally evacuated, and 2 cases with colic perforation)...

Dynamic imaging of the vocal tract using real-time MRI has been an active and growing area of research, having demonstrated great potential to become routinely performed in the clinical evaluation of speech and swallowing disorders. Although many technical advances have been made in regards to acquisition and reconstruction methodologies, there is still no consensus in best practice protocols. This study aims to compare Cartesian and non-Cartesian real-time MRI sequences, regarding image quality and temporal resolution trade-off, for dynamic speech imaging...

BACKGROUND: Congenital cystic lesions of the oral cavity are an extremely rare occurrence. Their prenatal diagnosis is essential since they can impede respiratory and swallowing functions. We describe a case that was detected prenatally and discuss its management. CASE REPORT: A 21-year-old primigravida patient who was 23 weeks pregnant was referred to our obstetrics and gynecology center after fetal ultrasonography showed a cystic lesion of the oral cavity. She had no family history of any congenital anomalies...

BACKGROUND: We aim to characterize serial (i.e., acute and late) MRI signal intensity (SI) changes in dysphagia-associated structures as a function of radiotherapy (RT) in nasopharyngeal cancer (NPC) patients. MATERIALS AND METHODS: We retrospectively extracted data on 72 patients with stage III-IV NPC treated with intensity-modulated RT (IMRT). The mean T1- and T2-weighted MRI SIs were recorded for the superior pharyngeal constrictor (SPC) and soft palate (SP) at baseline, early-after IMRT, and last follow up, with normalization to structures receiving <5 Gy...
