We report the case of a 57-year-old man who presented at the emergency department with injuries to his face and head after falling down the stairs. A head computed tomography examination done because he complained of an intense headache revealed air bubbles in the retropharyngeal space. Given this finding, a computed tomography of the neck was done to evaluate the possibility of pharyngeal perforation. Read More

Acinetobacter species frequently causes nosocomial infection, particularly in patients receiving invasive ventilation at intensive care units for a prolonged period. Odynophagia is a rare, initial clinical manifestation of prevertebral abscess which subsequently develops when the abscess extends into the retropharyngeal space causing a midline bulge of the posterior pharyngeal wall. Here, we present and discuss a patient with uncontrolled diabetic mellitus who presented with severe odynophagia and dysphagia. Read More

Introduction: The clivus is a small, central area of the basal cranium with limited surgical access and high morbidity associated with pathologies of its surrounding structures. Therefore thorough knowledge and understanding of the anatomy in this region are crucial for the success of treatments and interpretation of imaging. As to our knowledge, there is no extant cadaveric examination of the transclival veins, so the present study was performed. Read More

Adenotonsillectomy is a common surgical otolaryngology procedure that is associated with several complications, including hemorrhage, odynophagia, damage to teeth, taste disorders, atlantoaxial subluxation, lingual edema, infection, and injury of the carotid artery. Pneumomediastinum, pneumopericardium, and epidural pneumatosis are an extremely unusual condition in children with adenotonsillectomy. Treatment should be conservative in the majority of cases and based on benign self-limiting course of these diseases; early recognition can prevent further complications. Read More

The development of a retropharyngeal hematoma may lead to acute airway compromise requiring emergent airway stabilization. We describe the development of a retropharyngeal hematoma in an elderly woman who sustained a fall from standing approximately 10 hours prior to symptom onset who was taking the antiplatelet agents clopidogrel and aspirin. This delayed onset of rapid airway compromise secondary to a retropharyngeal hematoma following a fall in a patient taking clopidogrel is an unusual and potentially life threatening event. Read More

Stridor is a common presenting symptom in young children and is produced by turbulent flow through the upper airway or trachea. In children under 12 months of age, stridor is commonly caused by laryngomalacia, tracheomalacia, croup, airway foreign body, and/or retropharyngeal abscess. In atypical presentations of stridor, soft tissue neck radiographs can be helpful to determine the underlying etiology. Read More

Background And Aim: Brucellosis is a major constraint to livestock production in Egypt as well as many developing countries worldwide. Bovine brucellosis is an economically important disease with reproductive failure as a principal manifestation resulting in abortion, premature birth and decreased milk production in females, and orchitis and epididymitis in males. In spite of the efforts of Egyptian veterinary services to overcome brucellosis, the disease is still prevalent in both animals and humans and represents one of the most important public health hazards in Egypt.

There are multiple reasons for imaging the soft tissues of the neck in the emergency setting, in particular when symptoms are vague or if there is worry for complications from a certain clinical diagnosis. When fluid is seen in the retropharyngeal space, it is important to pay attention to history and look at key structures in the neck. This article will discuss anatomy of the retropharyngeal space, followed by four causes of fluid within the space that the radiologist is likely to encounter in the emergency setting: tonsillitis/pharyngitis, acute calcific tendinitis of the longus colli muscles, internal jugular vein thrombosis, and post-radiation changes.
