This type of connective tissue is found mostly in the reticular layer (or deep layer) of the dermis. [3] It is also in the sclera and in the deeper skin layers. Due to high portions of collagenous fibers, dense irregular connective tissue provides strength, making the skin resistant to tearing by stretching forces from different directions.
The epineurium is the outermost layer of dense irregular connective tissue surrounding a peripheral nerve. [1] [2] It usually surrounds multiple nerve fascicles as well as blood vessels which supply the nerve. Smaller branches of these blood vessels penetrate into the perineurium. [3]
The submucosa (or tela submucosa) is a thin layer of tissue in various organs of the gastrointestinal, respiratory, and genitourinary tracts. It is the layer of dense irregular connective tissue that supports the mucosa (mucous membrane) and joins it to the muscular layer, the bulk of overlying smooth muscle (fibers running circularly within layer of longitudinal muscle).
Consolidation or infiltrate can be dense or patchy and might have irregular, ill-defined, or hazy borders. Dense homogenous opacity in right, middle and lower lobe of primary pulmonary TB. Chest x-ray showing patchy opacification on the upper right and mid-zone lung with fibrotic shadows, as well as bilateral hilar lymphadenopathy.
CT scans have 90% accuracy in the diagnosis of pulmonary sequestration. The most common appearance is a solid mass that may be homogeneous or heterogeneous, sometimes with cystic changes. Less frequent findings include a large cavitary lesion with an air-fluid level, a collection of many small cystic lesions containing air or fluid, or a well ...
Fibrosis can be used to describe the pathological state of excess deposition of fibrous tissue, as well as the process of connective tissue deposition in healing. [3] Defined by the pathological accumulation of extracellular matrix (ECM) proteins, fibrosis results in scarring and thickening of the affected tissue — it is in essence a natural ...
Furthermore, when a patient lays supine for a CT scan, the posterior lungs are in a dependent position, causing partial collapse of the posterior alveoli. This leads to an increase in density of the tissue, resulting increased attenuation and a possible ground-glass appearance on CT.
In medicine, desmoplasia is the growth of fibrous connective tissue. [1] It is also called a desmoplastic reaction to emphasize that it is secondary to an insult . Desmoplasia may occur around a neoplasm , causing dense fibrosis around the tumor, [ 1 ] or scar tissue ( adhesions ) within the abdomen after abdominal surgery.
