Fetal meningocele symptoms?

summary

Fetal encephalocele and meningocele are two types of cystic cranial fissure, which can be caused by primary defect of neural tube. It contains brain tissue or partially dilated ventricles. The clinical manifestations vary with the location and size of the bulge. Fetal meningocele symptoms? Let's talk about it.

Fetal meningocele symptoms?

Most of the masses are small at birth, and gradually grow up later. Soft and compressible masses may appear along the midline of the face, head, skull or back, and may be Transilluminated or enlarged due to crying. In occipital part, round or oval cystic masses were seen at the junction of occipital and parietal. In the cases with nasal root, there are masses protruding in the nasal root, orbital distance widening, orbital cavity narrowing and eye shape triangular.

Neurological symptoms include mental retardation, convulsion, paralysis, tendon hyperreflexia, cortical visual impairment and cerebellar symptoms and signs. Some patients had no neurological symptoms. Black hair bundles or baldness areas surrounded by black hair circles can occur above the mass. Many skin lesions can be inferred from the deformities of other spinal cord and associated structures.

Skin manifestations of spinal insufficiency include sunken lesions, dermal lesions, pigmented lesions, hair lesions, polypoid lesions, tumor, subcutaneous tissue and vascular lesions.

matters needing attention

With the fetal ultrasound examination and maternal blood α- In the routine application of fetal protein test, encephalocele can be diagnosed in utero, which plays an important role in deciding whether to terminate pregnancy. Fetal ultrasonography can find large encephalocele, and it is easy to detect whether there is solid tissue in the capsule. Hydrocephalus is not often found in prenatal ultrasound. In fact, hydrocephalus rarely occurs at birth, usually after posterior cranial encephalocele repair. In ultrasound examination, pay attention to distinguish from encephalocele are tumors in skull, scalp or high neck. These lesions are more rare than encephalocele. raise an exception α- The necessary condition of fetoprotein is leakage of tissue fluid and cerebrospinal fluid. If the lesion is completely epithelialized, even if the skin is dysplasia, the mother's blood and amniotic fluid may be damaged α- Fetoprotein levels were also normal.
