THE CLINICAL SYNDROME

• Retropharyngeal abscess was once a disease that was nearly never seen in adults and almost always seen in children, but now days it's becoming more common in adults.

• It is possible for this to develop as a consequence of an infection in the upper respiratory tract, trauma to the posterior pharynx (such as challenging endotracheal intubation), or perforation caused by a foreign body, amongst other potential reasons.

• A retropharyngeal abscess can lead to life-threatening complications and even death if it is left untreated. Unfortunately, this condition is frequently misdiagnosed. Mortality and morbidity associated with retropharyngeal abscess are primarily the result of airway obstruction, mediastinitis, spread of infection to the epidural space, necrotizing fasciitis, erosion into the carotid artery, and, in immunocompromised patients, overwhelming sepsis.

• Other contributing factors include: spread of infection to the epidural space; spread of infection to the epidural space; spread of infection to the carotid The prevertebral fascia, the buccopharyngeal fascia, and the carotid sheaths are the three structures that enclose the retropharyngeal space, which is located behind the pharynx.

• Laterally, the retropharyngeal space is bordered by the carotid sheaths.

• The retropharyngeal space, which extends from the base of the skull inferiorly to the mediastinum, is prone to infection by both aerobic organisms such as Streptococcus, Staphylococcus, and Haemophilus and anaerobic organisms such as Bacteroides.

• These organisms can be found anywhere along the length of the space. In immunocompromised patients, fungal and mycobacterial infections of the retropharyngeal space have been observed sporadically.

SIGNS AND SYMPTOMS

• At first, the patient who has a retropharyngeal abscess will complain of pain that is difficult to pinpoint in the region where the infection is located.

• At this stage, it is possible for the patient to experience some mild discomfort during swallowing as well as in the range of motion of the cervical spine.

• It's possible that the posterior pharyngeal enlargement will show up on the physical exam at this stage. There is a possibility that you will get a fever of a low degree or nocturnal sweats.

• If the patient has been given steroids, there is a possibility that these constitutional symptoms may be less severe or that the development of these symptoms will be postponed.

• The patient appears to be in a critical condition, as evidenced by a high temperature, rigors, and chills, as the abscess becomes larger.

• Because the patient is having more trouble swallowing, there is a possibility that they will be drooling.

• Additionally, nuchal stiffness and stridor in the respiratory system may be present.

• Even when rigorous medical and surgical treatment is being administered, a high death rate is related with the cancer having spread to the mediastinum and the central nervous system.

TESTING

• More than 80% of patients suffering from retropharyngeal abscess show widening of the retropharyngeal soft tissues on lateral radiography of the neck.

• Less than 10% of patients have clearly defined soft tissue masses with air-fluid levels suggestive of abscess.

• Since magnetic resonance imaging (MRI) and high-speed computed tomography (CT) scans are both easily available in this day and age, it may be more wise to obtain these noninvasive tests first, given the very specific diagnostic information that can be received from them.

• The diagnosis of retropharyngeal abscess can be made with a high level of precision using either MRI or CT, and both of these imaging modalities should be obtained as soon as possible in any patient who may be suffering from this condition.

• An abscess in the retropharynx can also be identified by the use of ultrasonography.

DIFFERENTIAL DIAGNOSIS

• If a patient has a history of trauma to the retropharyngeal space, the diagnosis of retropharyngeal abscess should be strongly considered in any patient who has a sore throat, fever, neck pain, painful and difficult swallowing, and posterior pharyngeal swelling.

• This is especially true in patients who have a sore throat, fever, neck pain, painful and difficult swallowing, and posterior pharyngeal swelling.

• Conditions that are frequently misdiagnosed as retropharyngeal abscess Patients who have been treated with steroids or who are immunocompromised may have a reduction in the constitutional symptoms that are linked with serious infections (e.g., acquired immunodeficiency syndrome, malignant disease).

TREATMENT

• If the patient wishes to avoid major morbidity and mortality, it is imperative that treatment for retropharyngeal abscess be initiated as quickly as possible.

• In order to treat retropharyngeal abscess, two things need to be accomplished: first, the infection has to be treated with antibiotics, and second, the abscess needs to be drained in order to relieve pressure on the structures that are nearby, including the airway.

• Because many retropharyngeal abscesses are caused by Staphylococcus aureus, the first antibiotic treatment should include vancomycin to treat staphylococcal infection.

• This is because many retropharyngeal abscesses are caused by Staphylococcus aureus.

• It is also important to begin empirically administering antibiotic treatment for gram-negative and anaerobic bacteria as soon as culture samples of blood and urine have been obtained.

• As culture and sensitivity reports become available, antibiotic treatment can be adapted to meet the needs of the patient based on these factors.

• Antibiotic treatment shouldn't be put off while waiting for a final diagnosis if retropharyngeal abscess is being evaluated as part of the differential diagnosis, as was previously mentioned.

COMPLICATIONS AND PITFALLS

• If a clinician does not promptly and accurately diagnose and treat a retropharyngeal abscess, the outcome can only be catastrophic for both the clinician and the patient.

• If a clinician does not recognize the spread of infection into the central nervous system in a patient with retropharyngeal abscess, this can lead to permanent neurologic damage.

• The insidious onset of airway compromise associated with retropharyngeal abscess can lull the clinician into a sense of false security. if there is a suspicion of a retropharyngeal abscess.
