There is also a septation which is calcified. Yet, the cyst does not show enhancement (uptake of contrast). This category includes renal cysts with multiple thin septa, a septum thicker than hairline, slightly thick wall, or with calcification, which may be thick. It also includes intrarenal cysts larger than 3 centimetres (1.2 inches) if:
Primary familial brain calcification [1] (PFBC), also known as familial idiopathic basal ganglia calcification (FIBGC) and Fahr's disease, [1] is a rare, [2] genetically dominant or recessive, inherited neurological disorder characterized by abnormal deposits of calcium in areas of the brain that control movement.
The basal ganglia is a collective group of structures in the brain. These include the striatum, (composed of the putamen and caudate nucleus), globus pallidus, substantia nigra, and the subthalamic nucleus. Along with other structures, the basal ganglia are part of a neural circuit that is integral to voluntary motor function. [1]
The basal ganglia are of major importance for normal brain function and behaviour. Their dysfunction results in a wide range of neurological conditions including disorders of behaviour control and movement, as well as cognitive deficits that are similar to those that result from damage to the prefrontal cortex .

The most consistent finding are widespread calcifications, which involve the white matter of the cerebrum mostly adjacent to the junction with the grey matter, the thalami, the basal ganglia and the brainstem. [1] [2] The white matter of the cerebellum and the dentate nuclei are less often involved. However, the brain may appear normal in the ...
Cystic kidney disease includes various conditions related to the formation of cysts in one or both kidneys. The most common subset is polycystic kidney disease (PKD), which is a genetic anomaly with two subsets, autosomal recessive polycystic kidney disease (ARPKD) and autosomal dominant polycystic kidney disease (ADPKD).
Basal ganglia calcification is observed in all patients reported to date and represents the underlying autoinflammatory disease of excessive IFN-I activity, known as type I interferonopathy. [15] The basal ganglia calcifications may cause epileptic seizures but often are asymptomatic.
The length of the adult kidney is normally 10–12 cm, and the right kidney is often slightly longer than the left kidney. The adult kidney size is variable due to the correlation with body height and age; however, normograms for pediatric kidney size are available. [1]
