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 ]
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 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]
The diagnosis of branchial cleft cysts is typically done clinically due to their relatively consistent location in the neck, typically anterior to the sternocleidomastoid muscle. For masses presenting in adulthood , the presumption should be a malignancy until proven otherwise, since carcinomas of the tonsil, tongue base and thyroid may all ...
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]
The tissue in the lungs becomes thick and stiff, which affects the tissue that surrounds the air sacs in the lungs. [7] Symptoms typically include gradual onset of shortness of breath and a dry cough. [1] Other changes may include feeling tired, and clubbing abnormally large and dome shaped finger and toenails.

This category of cysts takes over areas of necrotic tissue in the brain from injuries, diseases, or abnormalities, which occur due to the central nervous system's nonregenerative nature. These cysts can affect all germ layers of the CNS, but are most common in the arachnoid mater , and the ventricular space , which may block CSF pathways.
