A posterior space abscess causes swelling in the posterior pharyngeal wall, and lockjaw is minimal. Other structures within the carotid sheath may be involved, causing rigors, high fever, bacteremia, neurologic deficit, or a massive haemorrhage caused by carotid artery rupture.
A CT scan shows a solid mass of Tornwaldt's cyst and MRI shows a glass-shaped lesion with fluid on the upper part of the posterior nasopharyngeal wall. Additionally, a cystic mass in the upper part of the nasopharyngeal wall and mucopurulent discharge from upper part of the mass can be seen on nasal endoscopy. Among them MRI is the best for ...
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.
The danger space serves as an important pathway for complicated infections of the posterior pharynx to enter the chest and spinal column. Anterior to the parapharyngeal space is the masticator space which contains the lower dental row, muscles of mastication, the inferior alveolar nerve as well as branches of cranial nerve V.
Peripheral edema is edema (accumulation of fluid causing swelling) in tissues perfused by the peripheral vascular system, usually in the lower limbs. In the most dependent parts of the body (those hanging distally ), it may be called dependent edema.
Angioedema is an area of swelling of the lower layer of skin and tissue just under the skin or mucous membranes. [1] [3] The swelling may occur in the face, tongue, larynx, abdomen, or arms and legs. [1] Often it is associated with hives, which are swelling within the upper skin. [1] [3] Onset is typically over minutes to hours. [1]
A Zenker's diverticulum, also pharyngeal pouch, is a diverticulum of the mucosa of the human pharynx, just above the cricopharyngeal muscle (i.e. above the upper sphincter of the esophagus). It is a pseudo diverticulum or false diverticulum (only involving the mucosa and submucosa of the esophageal wall, not the adventitia), also known as a ...
If the impaired vein function causes significant symptoms, such as swelling and ulcer formation, it is referred to as chronic venous disease. [3] It is sometimes called chronic peripheral venous insufficiency and should not be confused with post-thrombotic syndrome in which the deep veins have been damaged by previous deep vein thrombosis .
