cranial skin
Introduction
Introduction The cutis verticis gyrata is a similar skin-relaxation deformity that occurs in the skull skin. It is characterized by overgrowth of the skull and becomes most wrinkles, like a cerebral gyrus. It can be divided into primary and secondary. The former are mostly congenital developmental defects, such as pachydermoperiostosis. The latter often associated with local inflammatory diseases, neurofibromatosis, sputum, trauma or other proliferative diseases, acromegaly, leukemia, small head idiots, mucinous edema, dysplasia and other diseases.

Cause
(1) Causes of the disease:
It can be divided into primary and secondary. The former are mostly congenital developmental defects, such as pachydermoperiostosis. The latter often associated with local inflammatory diseases, neurofibromatosis, sputum, trauma or other proliferative diseases, acromegaly, leukemia, small head idiots, mucinous edema, dysplasia and other diseases.
(2) Pathogenesis:
The pathogenesis is still not clear. The skin is loose and deformed for the skull skin, and the cranial skin grows excessively, becoming a majority of wrinkles, like a cerebral gyrus.

Brain CT examination blood routine
The number of cranial skin formation varies from strip wrinkles to cerebral gyrus, and each fold is about 1 cm wide. More common in men, it occurs on the top of the head, but the hair is normal. According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
Diagnosis
Differential diagnosis
Scalp sag: It is a symptom of hypertrophic osteoarthrosis. The scalp is thickened and the cerebral palpebral fold is thick, the sulcus is obvious, and the longitudinal direction of the head is changed. This type of cerebral cerebral palsy is called scalp sag. X-ray examination, the main X-ray changes of this disease are long bone and short bone symmetry periosteal new bone formation. It can be expressed as parallel or layered, separated from the cortex by a linear translucent band, or as a fusion of the periosteal new bone with the original cortex, without a translucent band, wavy or extensive spinous periosteal callus.
Baby scalp blood stasis: common in dry eczema, more common in thin infants. Occurs in the scalp, eyebrows and other parts, showing flushing, scaling, and papules, but no obvious exudation. It can also be slightly infiltrated and hypertrophic when it is chronic, with cleft palate, scratches or blood stasis. Often due to paroxysmal intense itching, the baby is crying and restless.
Scalp hematoma: mostly due to blunt injury and scalp. According to the specific level of hematoma appearing in the scalp, it can be divided into subcutaneous hematoma, subarachnoid hematoma and subperiosteal hematoma.
1. Subcutaneous hematoma: Because the connection between the subcutaneous tissue and the skin layer and the aponeurotic layer is tight, the hematoma in this layer is not easy to spread and the scope is limited. The soft tissue around the hematoma is swollen, and there is a sense of depression and tenderness. It is easy to be confused with the sag fracture. Sometimes it needs to be confirmed by X-ray examination of the skull.
2. Capular subdural hematoma: caused by rupture of small arteries or blood vessels in this layer. The lower layer of the aponeurotic aponeurosis is loose, and the hematoma easily spreads and even spreads to the entire lower layer of the aponeurotic aponeurosis. The blood content can be as much as several hundred milliliters, the tension is low, and the pain is light.
3. Subperiosteal hematoma: bleeding is mostly caused by platelet hemorrhage or periosteal stripping. The range is limited to the bone seam and the texture is hard.
