What is a fetal lobulation?

Persistent fetal lobulation is a normal variant seen occasionally in adult kidneys. It occurs when there is incomplete fusion of the developing renal lobules. Embryologically, the kidneys originate as distinct lobules that fuse as they develop and grow.

What does mild lobulation mean?

A lobulation is an appearance resembling lobules. For instance, the thyroid gland may become large and lobulated in Hashimoto’s thyroiditis. Fetal lobulation, also known as fetal lobation, of the kidney is evident on scanning. Fetal lobation is a normal stage in the development of the kidney.

What does kidney lobulation mean?

Renal pseudotumours are defined as real or simulated kidney masses which resemble tumours on imaging, although they consist of benign renal tissue. 1. They fall in different categories such as developmental, infectious, granulomatous and vascular.

What is cortical scarring?

Cortical scarring was defined as a defect in the normal reniform outline. A photon deficient area was defined as a focal or diffuse area of reduced uptake of the radionuclide with preservation of the normal reniform outline.

What is the meaning of lobulated?

: made up of, provided with, or divided into lobules a lobulated tumor. Comments on lobulated.

Is renal agenesis genetic?

Most cases of renal agenesis are not inherited from the parents, nor do they result from any behavior by the mother. Some cases, however, are caused by genetic mutations. These mutations are passed on from parents who either have the disorder or are carriers of the mutated gene.

What’s the meaning of lobulated?

What is a hyperintense mass?

A mass that is higher in SI than is skeletal muscle on T1-weighted images is considered to be hyperintense.

What is horse shoe kidney?

Horseshoe kidney is a condition in which the kidneys fuse (bind) together at the bottom, forming a “U” shape or horseshoe shape. Children who have horseshoe kidney have one “fused” kidney instead of 2 separate kidneys.

What causes scarring of the kidneys?

Kidney scarring, or ‘fibrosis’ is the primary cause of kidney disease and is triggered by factors including diabetes, autoimmune disease and high blood pressure, regular use of certain medications and prolonged infections.

What is cortical scarring of kidneys?

Scarring is an non-specific response of the kidney to injury. Scarring can occur because of high blood pressure, infection, glomerulonephritis, trauma, drug induced injury, blockage of the ureter, blockage of the blood vessel and chemical injury. You can also be born with this abnormality.

What does persistent fetal lobulation of kidney mean?

Renal pseudotumour is a term coined to describe conditions of renal anatomic variants that simulate focal renal pathology like a tumour on ultrasonography. These include persistent fetal lobulation, hypertrophy of Bertin columns and dromedary humps.

What kind of abnormity is the lobulated liver?

The lobulated liver is either a congenital abnormity or an acquired malformation.

How are the lobules different from the lobes of the liver?

The hepatic lobule is a building block of the liver tissue, consisting of a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein. Lobules are different from the lobes of the liver: they are the smaller divisions of the lobes.

How is the inferior surface of the liver shaped?

The inferior surface tends to be flat, but there are undulations caused by moulding of the liver to the abdominal organs which relate to its inferior surface. The right lobe is quadrilateral in shape while the left lobe is tongue-shaped with a relatively thin inferior margin.
