Abnormal Soft Tissue Neck X-Ray

Abnormal soft tissue neck x-rays have a variety of diagnostic uses. They can demonstrate abnormal air-fluid levels within a normal air-filled structure, which may indicate an abscess, and they can identify radiopaque foreign bodies. However, many soft-tissue abnormalities are not easily distinguishable on x-rays and may only be detected through a more extensive examination.

a laryngeal mass with extensive air-fluid level in the retropharyngeal space

A laryngeal mass with extensive fluid level in the retropharyngeous space may be an obstructing mass that obstructs airway function. It is rare in adults but is common in newborns. A laryngeal mass with extensive gas-fluid level in the retroparyngeal space typically appears as a well-defined mass in the subglottic airway with eccentric narrowing of the laryngeal vestibule. In addition, additional hemangiomas may occur on the skin and elsewhere in the body.

The retropharyngeal space is a virtual space containing the retropharyngeal lymph nodes and some fatty tissue. Its presence allows for the spread of infections of the mouth and throat. It is situated posteriorly to the pharynx and anterior to the esophagus. It is bounded by the buccopharyngeal and prevertebral fascia and the longus colli muscles.

When a laryngeal mass is present in the retropharyngeal cavity, it may be due to epiglottitis. Epiglottitis is characterized by thickened epiglottis and aryepiglottic folds. This condition also causes mild hypopharyngeal overdistention.

a laryngeal mass with paralysis of the left piriform sinus

This patient has an abnormal soft tissue neck x-ray with a paralysis of the left piriform canal and mass in the left piriform sinus. This is a very rare condition. It is usually diagnosed at an advanced stage. This tumor often extends into the larynx or other structures of the neck.

A laryngeal mass that occludes the left piriform sinus is often a sign of a soft-tissue infection in the area. This mass typically has a fluid density and is located in the supraglottic larynx. It also has a significant extralaryngeal component, which can explain the mass on the right side of the neck.

The presence of air in the soft tissues of the neck indicates a variety of different conditions, including pneumomediastinum or a retropharyngeal abscess. The underlying soft tissues in the neck can also be an indication of an air leak. X-ray and CT studies of the neck can help in identifying this condition.

a laryngeal mass with a mass occupies and obscures the left piriform sinus

A laryngeal mass that occupies and obscures the left piric sinus is indicative of a soft-tissue infection in the airway. This type of mass usually causes complete paralysis of the right vocal cord, which passes through the left piriform sinus. This mass could also indicate an adjacent infection.

The larynx is located ventrally between the anterior two cervical vertebrae. Anatomical dissection and computer tomography imaging can determine the exact position of the larynx. The thyrohyoid cartilage articulates with the rostral horn of the thyroid cartilage, which is located in the larynx. The pharyngeal constrictors also attach to the ventral surface of the surrounding neck musculature.

The larynx of the male Mongolian gazelle is more than 0.5 kg in weight and is suspended from the anterior neck region. This structure was likely favored by sexual selection, male-male competition, and female choice. The larynx has a distinct contour and is roughly circular in shape, and it is 75mm wide and 125mm long.
