Patient's question:
A 5-month-old fetus was found to have a cyst in the brain during a 4D ultrasound, with a significant difference in the thickness of the two blood vessels.Doctor's answer:
A brain cyst is a condition where a cystic mass forms between brain tissue and its, causing varying degrees of intracranial pressure symptoms. Brain cysts are benign tumors, and due to their large size, they exert pressure on the brain, forming one of the space-occupying lesions. During the formation of space-occupying lesions, the brain tissue is compressed by the expanding cyst, leading to a series of compressive symptoms. Among these, ptosis with narrowed palpebral fissures, paralytic esotropia, and limb dysfunction are quite common.
