Fluid collections in the retropharyngeal space (RPS) result from a wide spectrum of diseases, including retropharyngeal abscess, cervical osteomyelitis, and calcific tendinitis of the longus colli muscle . Ostensibly, these abnormalities would tend to be diffuse and bilateral, though unilateral lingual edema on CT has been reported. 2 Similarly,. The retropharyngeal space (RPS) extends from the skull base to the upper mediastinum at T1 to T6 level. It is located posterior to the pharynx and esophagus and anterior to the perivartebral space (FIG 1). The space is surrounded anteriorly by the pharyngeal mucosal space; laterally by the parapharyngeal and carotid spaces and posteriorly by.
The retropharyngeal space is now distended and shows increased density of the fatty tissue due to post-radiotherapy edema. Posterior cervical space On the left a table with the normal contents of the posterior cervical space and subsequent pathology . Retropharyngeal edema spread craniocaudally between soft palate and upper half of thyroid cartilage in all patients. No edema fluid extended above soft palate and below thyroid cartilage of the retropharyngeal space by mucoid or water attenuation without evidence of an enhancing rim. When a suppurated lymph node ruptures into the retropharyngeal space, a true retropharyngeal abscess may form with an enhancing wall as its imaging hall-mark. Edema in the retropharyngeal space may also occur as an expected side effect of.
Although retropharyngeal abscess is most common in children under the age of 6 years, it is becoming increasingly frequent among adults, particularly those who are immunocompromised and those with a spinal infection resulting from trauma (2). Lateral radiography may depict prevertebral swelling or air within the prevertebral soft tissues One potential presentation is retropharyngeal edema, defined as fluid in the retropharyngeal space. Multiplanar imaging with computed tomography or magnetic resonance imaging is ideal for characterizing and diagnosing these fluid collections rapidly as possible life-threatening complications may develop (eg, airway obstruction and mediastinitis) Retropharyngeal edema has more benign imaging features, with tapered inferior and superior margins, minimal mass effect, and no rim enhancement (Figure 5). 9 There are multiple etiologies, including recent radiation therapy, IJV thrombosis, pharyngeal infection, and longus colli calcific tendinitis
The diagnostic work-up comprising lateral radiograph, CT and MR imaging disclosed the rare constellation of a retropharyngeal hematoma and prevertebral edema without further injury of the cervical spine structures. Compression of the upper airways was evident The pharyngeal infection is manifest in (D) by ulceration, mucosal enhancement and edema within the pharyngeal wall (arrows), and edema spreading in the RS (arrowheads).

On CT, a rim-enhancing fluid collection confined to the lateral margin of the retropharyngeal space with adjacent inflammatory stranding is compatible with retropharyngeal suppurative lymphadenitis (Figure 8). 17 There is typically associated retropharyngeal edema or effusion, but rim-enhancing fluid should not cross the midline or fill the.

Symptoms of neck inflammation are common in MIS-c Initially there is presentation of lymphadenitis with RPS edema or phlegmon.

Inaba, MD The retropharyngeal space extends from the base of the skull down to the level of the carina, and is located between the buccopharyngeal mucosa and the prevertebral fascia Edema or collections within the retropharyngeal space occur in retropharyngeal abscess usually following rupture of suppurated lymphadenitis, in radiotherapy, as sequela of resection of a jugular vein and in trauma to the cervical spine. Diseases of the spine like infections and tumours can also induce edema within the retropharyngeal space
The differential diagnosis of a retropharyngeal fluid collection on imaging is extensive, and the edema associated with tendonitis can be confused with a retropharyngeal abscess. Pathognomonic radiologic findings in RCT are the presence of a prevertebral effusion from C1 to C4 and calcifications below the anterior arch of C1 possible retropharyngeal edema that smoothly expands the retropharyngeal space in all directions. It radiologists and otolaryngologists to differentiate between these findings and those of retropharyngeal infection, in order to institute appropriate treatment and avoid invasive therapies such as intubation and surgical drainage. 1 Acute calcific tendinitis of the longus colli muscle is an inflammatory condition associated with calcifications in longus colli muscle fibers which can present as acute neck pain. We present a case of a patient presenting with acute neck pain. MRI showed retropharyngeal effusion and edema of the left side longus colli muscle Kawasaki disease with retropharyngeal edema (KD with RPE) is a rare complication, and it is diagnosed by neck CT. Most reported cases had a delayed diagnosis because those patients' conditions were misdiagnosed as retropharyngeal abscess (RPA). The purpose of this study was to differentiate KD with RPE from RPA. We performed a retrospective case-control study comparing children with KD with.
Retropharyngeal abscess (RPA) produces the symptoms of sore throat, fever, neck stiffness, and stridor. RPA occurs less commonly today than in the past because of the widespread use of antibiotics for suppurative upper respiratory infections. The incidence of RPA in the United States is rising, however Retropharyngeal hematoma (RPH) is rare.2The most serious sequela of RPH is respiratory obstruction leading to death.3-5SGB can also cause RPH, although it is extremely rare.

Retropharyngeal abscess occurs less commonly today than in the past because of the widespread use of antibiotics for suppurative upper respiratory infections PERITONSILLAR abscess is a known cause of serious airway complications, and, in this context, is discussed in anesthesiology texts. 1,2Other medical literature contains reports of peritonsillar abscesses that spread along the deep fascial planes of the neck and chest.We report a rare case in which caudad spread of a peritonsillar abscess lead to life-threatening conditions in addition to. A contrast enhanced CT of the neck and chest showed fluid collections in multiple deep neck spaces including retropharyngeal, prevertebral, parapharyngeal and visceral neck spaces, with extension into the mediastinum (Fig 1).

Initial testing includes lateral neck radiography; however, visualizing the calcification is difficult. 10 CT of the cervical spine is the standard because it is more sensitive for demonstration of calcium hydroxyapatite deposits. 10 Compared with CT, MRI is superior in delineating edema along the retropharyngeal space but is inferior in terms. Acute retropharyngeal tendonitis (calcific tendonitis of the longus colli), initially described by Hartley in 1964, is an acute inflammation condition of the longus colli tendon, which is related to calcium hydroxyapatite deposition in the superior oblique fibers of the longus colli muscles.
