Retropharyngeal abscess. Retropharyngeal abscess (RPA) is an abscess located in the tissues in the back of the throat behind the posterior pharyngeal wall (the retropharyngeal space). Because RPAs typically occur in deep tissue, they are difficult to diagnose by physical examination alone. RPA is a relatively uncommon illness, and therefore may ...
Danger space. Section of the neck at about the level of the sixth cervical vertebra. Showing the arrangement of the fascia coli. The danger space or alar space, is a region of the neck. [1] The common name originates from the risk that an infection in this space can spread directly to the thorax, and, due to being a space continuous on the left ...
Prevertebral space. Section of the neck at about the level of the sixth cervical vertebra. Showing the arrangement of the fascia coli. Sagittal section of nose mouth, pharynx, and larynx. Anatomical terminology. [edit on Wikidata] The prevertebral space is a space in the neck. On one side it is bounded by the prevertebral fascia.
Compartment syndrome. Compartment syndrome is a condition in which increased pressure within one of the body's anatomical compartments results in insufficient blood supply to tissue within that space. [6][7][8] There are two main types: acute and chronic. [6] Compartments of the leg or arm are most commonly involved.
It is iso-echogenic to the thyroid gland with no definite connection to the thyroid gland. b Transverse colour Doppler ultrasound shows significant increase in vascularity. c Axial enhanced neck CT scan at the level of thyroid cartilage demonstrates midline infrahyoid hyperdense soft tissue mass (white arrow) embedded within the strap muscle.

Thyroglossal cyst. A thyroglossal cyst or thyroglossal duct cyst is a fibrous cyst that forms from a persistent thyroglossal duct. Thyroglossal cysts can be defined as an irregular neck mass or a lump which develops from cells and tissues left over after the formation of the thyroid gland during developmental stages. [1]
Fascial spaces (also termed fascial tissue spaces[1] or tissue spaces[2]) are potential spaces that exist between the fasciae and underlying organs and other tissues. [3] In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection. The fascial spaces can also be opened during ...
Sternothyroid muscle. Section of the neck at about the level of the sixth cervical vertebra. Showing the arrangement of the fascia coli. (Sternothyroideus labeled at right, third from top.) The sternothyroid muscle (or sternothyroideus) is an infrahyoid muscle of the neck. [1] It acts to depress the hyoid bone.
