Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
The development of bronchiectasis requires two factors: an initial injury to the lung (such as from infection, auto-immune destruction of lung tissue, or other destruction of lung tissue (as seen in gastroesophageal reflux disease or aspiration syndromes)) which leads to impaired mucociliary clearance, obstruction, or a defect in host defense.
Meniscal cyst is a well-defined cystic lesion located along the peripheral margin of the meniscus, a part of the knee, nearly always associated with horizontal meniscal tears. Signs and symptoms [ edit ]
In adults cysts may also form due to a head injury or trauma, resulting in necrotic tissues (dead tissue), and can sometimes be associated with cancerous tumors or infection in the brain. However, the underlying reasons for cyst formation are still unknown.
Smaller (less than 0.5 cm) raised soft tissue bumps may be termed papules. [3] The evaluation of a skin nodule includes a description of its appearance, its location, how it feels to touch and any associated symptoms which may give clues to an underlying medical condition. [4] Nodules in skin include dermatofibroma [5] and pyogenic granuloma. [6]
The enlargement of the kidney can be related to the degree of cyst formation. The cysts which come from the Bowmans space can also cause the kidneys to appear asymmetrical or misshapen. Cysts can cause injury by destroying nearby renal tissue [10] Familial GCKD can have enlarged or normal size kidneys. [6]
From their common origin at a joint or tendon, ganglion cysts may form in a wide range of locations. Rarely, intraosseous ganglion cysts occur, sometimes in combination with a cyst in the overlying soft tissue. [6] [16] Rare cases of intramuscular ganglion cysts in the gastrocnemius muscle of the calf have been reported.
The cysts and cavities (cystic brain lesions) are more likely to be the result of destructive (encephaloclastic) cause, but can also be from abnormal development (malformative), direct damage, inflammation, or hemorrhage. [5] The cysts and cavities cause a wide range of physiological, physical, and neurological symptoms. [6]
