Lindow cyst is a further dilatation of blood vessels. The term “Lindau cyst” describes a serious vascular abnormality known as angioreticulomatosis (AR), one of the most common vascular tumors that affects the capillaries along the walls of the brain. It is one of the manifestations of the pathology of the internal carotid artery. Its occurrence is associated with changes in the endothelium and muscle tissue of blood vessels and makes it possible to detect this pathology not only in newborns, but also in adults and elderly patients. This condition occurs in various places of the head, most often the membranes of the brain, spine, eyes and blood vessels of the neck are affected. They can be unilateral (where they occur on only one side of the head) or bilateral (they occur on both sides of the head). A Linde cyst is the name that was given to this type of brain hemorrhage, but it is no longer used in medical circles today. instead it is usually called Lindau angioreticolomatosis Link: https://www2.deloitte.com/global/en/pages/life-sciences-health-care/articles/anatomy-of-lindau-disease.html? “This steadily evolving vascular disease is a rare type of arteriopathy of hereditary angiogenic origin. Lindau syndrome affects one of the 23 human chromosomes (chromosome 4p16).”[2][6] Lindau syndrome is the least known of the autosomal dominant syndromes, but it is more studied than other autosomal recessive conditions.
