Liver - Incidentalomas Incidental hypervascular lesions are also very common findings in liver imaging. It is important to differentiate between 'touch' and 'don't touch' lesions. Benign 'don't touch' hypervascular tumors include hemangioma, FNH and small adenomas.

- 'Lesion' is the word used for any abnormality. For example a small cyst on the liver could be called a lesion, as could a large neoplastic mass. Examples of lesions which … could be found on/in the liver; Neoplasms (including cancers), cysts, abscesses, granulomas and scar tissue from previous inflammation.

What are Kidney Lesions Detected? The world lesion is derived from the Latin term ‘laesio’ which means injury. Lesion encompasses a broad meaning and hence any damage to the tissue is termed as lesion. A kidney lesion is an abnormal tissue which is damaged by some malignant growth on kidney or near it.Many times metabolic processes like trauma, ulcer caused due to electrocution, skin diseases like chicken pox or chemical burns can cause lesions to kidney.sually kidney lesions do not cause any symptoms unless they are cancerous and hence are discovered when a routine CT scan is carried out, most probably for some other organ problem. More often when a patient suffers pain from kidney stones or gallstones he has to undergo lot of scans and tests.

Hypertrophic scar Hypertrophic scar (4 months after incident) A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.

- Cold Injector “Stiction” - Solution! A new calibration has been developed and extensively tested in lab and field over the past 6 months.! Removes the oil in the spool-endcap interface inside the injector by cycling the spool valves for 30 seconds.! At start up, the coils are left on longer to heat & thin the oil. The injector performs as if EOT is warm.! This is a permanent fix, more effective long-term than injector replacement (since any injector can develop stiction)

- Macrovascular disease: Disease of the large blood vessels, including the coronary arteries, the aorta, and the sizable arteries in the brain and in the limbs.Macrovascular disease is by contrast to microvascular disease.In persons with diabetes, chronic hyperglycemia (assessed by glycosylated hemoglobin level) is related to the development of microvascular disease; however, the relation of glycosylated hemoglobin to macrovascular disease is less clear.n persons with diabetes, chronic hyperglycemia (assessed by glycosylated hemoglobin level) is related to the development of microvascular disease; however, the relation of glycosylated hemoglobin to macrovascular disease is less clear.

Background Lymphomatoid papulosis (LyP) is a chronic papulonecrotic or papulonodular skin disease with histologic features suggestive of a malignant lymphoma. The disease is characterized by recurrent crops of pruritic papules at different stages of development that predominantly arise on the trunk and limbs.

Diabetic hyperglycemic hyperosmolar syndrome This is called hyperosmolarity. It is a condition in which the blood has a high concentration of salt (sodium), glucose, and other substances. This draws the water out of the body's other organs, including the brain.

Cavernous Angioma About Cavernous Angioma. A cavernous angioma is a blood vessel abnormality characterized by large, adjacent capillaries with little or no intervening brain. The blood flow through these vessels is slow. Cavernous angiomas can occur anywhere in the central nervous system.

What is a Hypoechoic Mass? A hypoechoic mass is a lump which appears relatively darker on an ultrasound scan, because it reflects fewer ultrasound waves. The significance of this finding varies depending on the context. Some tissues normally reflect more or less ultrasound waves than others.

Renovascular hypertension Renovascular hypertension (or renal hypertension ) is a condition which consists of high blood pressure caused by the kidneys ' hormonal response to narrowing of the arteries supplying the kidneys.When functioning properly this hormonal axis regulates blood pressure.he cause of renovascular hypertension is consistent with any narrowing/blockage of blood supply to the renal organ. As a consequence of this action the renal organs release hormones that indicate to the body to maintain a higher amount of sodium and water, which in turn causes bp to rise.

renovascular hypertension In atherosclerotic renovascular hypertension disease, plaque is deposited in the renal artery. The deposits narrow the artery, disrupting blood flow.

Clinical Characterization of Symptomatic Microangiopathic Brain Lesions Abstract. 1  Background: Microangiopathic brain lesions can be separated in diffuse lesions – leukoaraiosis – and focal lesions – lacunes. Leukoaraiosis and lacunes are caused by common cerebrovascular risk factors, but whether they represent a common entity is not sufficiently investigated.

- Hemangioma is the most common benign vascular tumor of bone. Most hemangiomas involve the vertebral body or skull, and involvement of other bones is rare. However, involvement of long and short tubular bones has been reported. Roentgenograms usually show multiple or multilocular lytic lesions.his appearance is mainly found in the vertebral body, but may extend into the neural arch (picture). On MRI, compared with most bony lesions, vertebral haemangiomas show increased SI on T1- and T2-weighted sequences because of their increased fat content.

- Vascular lesions are comprised of blood vessels that have formed in an abnormal pattern directly underneath the surface of the skin. This usually results in a red or purple lesion since the blood vessels can be visible through the skin. These lesions occur in many sizes, shapes and forms all over the body.

- Quick Answer. An echogenic lesion in the liver is a lesion which appears in the results of a liver ultrasound as either a lighter or darker coloring than the surrounding liver tissue. According to Wikipedia, echogenicity is the ability to bounce an echo back from tissue during an ultrasound examination. Continue Reading.

Hypertensive Retinopathy Hypertensive retinopathy is retinal vascular damage caused by hypertension. Signs usually develop late in the disease. Funduscopic examination shows arteriolar constriction, arteriovenous nicking, vascular wall changes, flame-shaped hemorrhages, cotton-wool spots, yellow hard exudates, and optic disk edema.

- 1 The lesion abuts the surface of the brainstem that abuts the pia mater, the outer covering of the brain. This type of lesion is called “exophytic”. · cute hemorrhage is external to the “capsule” of the lesion. In other words, blood from a hemorrhage is entering brain tissue surrounding the cavernous angioma.

Brain Lesions: Causes, Symptoms, Treatments A lesion is an area of tissue that has been damaged through injury or disease. So a brain lesion is an area of injury or disease within the brain.While the definition sounds simple, understanding brain lesions can be complicated.That's because there are many types of brain lesions.rain abscesses often occur after an infection, usually in a nearby area, such as an ear, sinus, or dental infection. They can also appear after injury or surgery to the skull. Arteriovenous malformations (AVMs): An AVM is a type of brain lesion that occurs during early development.

microaneurysm A minute aneurysmal dilation of arteries, arterioles or capillaries, which is classically seen in the retina of patients with long-standing diabetes and often associated with oedema and haemorrhage. Microaneurysms occur elsewhere in diabetes, as well as in other conditions (e.g., thrombotic thrombocytopenic purpura).
