Patient's question:
28 weeks of pregnancyHead: Head circumference 25.98, Cerebellar transverse diameter 3.76, Posterior fossa cistern 0.43, Ventricular ratio: within normal range.
Other findings are normal.
Others: Third ventricle width 0.92
Doctor's answer:
Hello, the transparent septal cavity is also known as the fifth ventricle, which is filled with cerebrospinal fluid and communicates with the lateral ventricles through the foramen of Monro. The normal transparent septal cavity should not exceed 10 mm. Isolated abnormalities in the transparent septal cavity or the fourth ventricle may be false positives or normal physiological changes. Based on your condition, as long as there are no other abnormalities, it should be considered a normal physiological situation. Currently, you are only 31 weeks pregnant. As the fetus develops, this mild expansion will gradually disappear with the maturation of the intracranial aqueduct system. Additionally, after birth, the bilateral transparent septal leaves will fuse, and the transparent septal cavity will disappear. There is no need to worry about anything. Currently, you should focus on increasing nutrition, maintaining a balanced diet, and preventing various infections (such as colds, diarrhea, etc.). Abstain from sexual activity. Regular prenatal check-ups are recommended. Wishing you a healthy pregnancy.
