Sotossyndrome, or cerebralgigantism, cerebralgigantismsyndromeinchildhood, also known as childhood giant brain syndrome ( macrencephalysyndrome, Sotos syndrome, is a syndrome in which the skeletal development grows too fast, the head is huge, and the intellectual development is delayed during infancy and school-age children. What are the tests for pediatric macrocephaly syndrome? 1.Chromosome examination Chromosome (Chromosome) is an object with genetic properties in the cell, easily dyed dark by alkaline dyes, so it is called chromosome (chromatin); chromosome is the material containing genetic information (genes) in the nucleus of the cell, which is cylindrical or rod-shaped under the microscope, mainly composed of deoxyribonucleic acid and protein, easily dyed by alkaline dyes (such as gentian violet and magenta acetate) during the mitotic period of the cell. It is easily colored by alkaline dyes (such as gentian violet and magenta acetate) during mitosis, hence the name. 2.Electroencephalography (EEG) is the basis of the physiological functions of the brain. The application of EEG is no longer limited to neurological diseases, but has been widely used in the monitoring of critical patients in various departments, anesthesia monitoring and psychological and behavioral research. In addition to routine EEG examination, there are long-term EEG monitoring, video EEG monitoring, sleep monitoring and digital computer analysis. 3.Cranial MRI examination Cranial MRI examination is an MRI examination of the brain, which is used to observe whether there are lesions in the brain and can clarify whether the patient is caused by structural changes in the brain. Intracranial tumors often cause epilepsy, and MRI has an extremely high diagnostic confirmation rate for low-grade astrocytomas, ganglia, gliomas, arteriovenous malformations and hematomas in the brain. 4.CT examination of the skull CT examination of the skull is a method of examining the skull through CT. It can clearly show the anatomical relationship of different cross-sections of the skull and the specific brain tissue structure. Thus, it greatly improves the detection rate of lesions and the accuracy of diagnosis. In general, CT has better visualization of human hard tissues than soft tissues. Cranial CT examination is important for the diagnosis of most diseases of the skull, cranium, and scalp (including trauma, tumors, inflammation, vascular lesions, poisoning, degenerative and metabolic diseases, etc.).
