Imaging of the oral cavity and pharynx often is required in three settings: assessment of an inflammatory mass in association with odontogenic, tonsillar, or pharyngeal infections; determination of the cause of a submucosal mass; and staging of squamous-cell carcinomas. Spread of infection from the oral cavity and pharynx can lead to abscesses in the masticatory space, the retropharyngeal compa...

Zenker's diverticulum is a pseudodiverticulum through a muscular defect in the posterior pharyngeal wall at the area between the inferior pharyngeal constrictor muscles of the pharynx and the cricopharyngeus muscle. Although endoscopic techniques have made significant progress, the surgical treatment remains the gold standard. There are two main techniques: diverticulectomy (resection of the di...

Figura 1 Presentamos el caso de una paciente de 44 años, con retraso mental y epilepsia como antecedentes más destacados, que sufre un atragantamiento mientras comía carne de conejo. Tras una primera exploración con fibroscopia flexible, se realiza TAC cervico-torácico, donde se aprecia aumento de partes blandas de localización retrofaríngea y moderada cantidad de enfisema subcutáneo y preverte...

Foreign body impaction in the neck poses life-threatening problems when it is deep and close to vital structures. We report two cases of sharp metallic foreign body impaction in the neck – one of them in the prevertebral space and the other in the intervertebral disk space. A neck exploration and surgical removal of these foreign bodies, as is usually practised in most centers, would have been ...

By use of in situ hybridization experiments, the mouse homeobox genes Hox-3.1 and Hox-1.5 are compared in the temporal and spatial patterns of their embryonic transcripts. Transcripts of both genes are first detected at about 7 1/2 days, although the appearance of Hox-3.1 transcripts apparently follows Hox-1.5 after a small delay. Hox-3.1 and Hox-1.5 transcripts occupy domains which are differe...

Central cord syndrome (CCS) is extremely rare as a direct consequence of generalized epileptic seizure. CCS is associated with hyperextension of the spinal cord and has characteristic radiologic findings including posterior ligamentous injury and prevertebral hyperintensity following magnetic resonance imaging (MRI). We experienced the case of a 25-year-old man who suffered CCS after status epi...

The coeliac plexus is located on the sides of the coeliac trunk and nearby the origins of the superior mesenteric and renal arteries. Afferent branches get to this plexus from the vagus nerve, splanchnic nerves and the right phrenic nerve; efferents leave for viscera through periarterial plexuses and the retroportal nerves. The coeliac plexus ganglia - coeliac, superior mesenteric, aorticorenal...

Introduction Spinal tuberculosis (TB) is a relatively common cause for spinal pathology in Sri Lanka and a common indication for magnetic resonance imaging (MRI). Objectives The objective of the study was to describe the MRI imaging pattern of spinal TB in a series of patients. Methods One hundred and nine patients with clinically confirmed spinal tuberculosis who had undergone MRI scans at...

The endoscopic endonasal approach is emerging as a feasible alternative to the transoral route for the resection of the odontoid process, when the latter produces a compression of the brainstem and cervicomedullary junction. This type of approach has some advantages, such as excellent prevertebral exposure of the craniovertebral junction in patients with small oral cavities and the possibility ...
