For patients with hydrocephalus, an examination using cranial MRI often shows significant dilation of the ventricular system, especially in patients with communicating hydrocephalus, where the entire ventricular system can appear significantly dilated. Once such a condition is discovered, it is advisable to promptly visit a local hospital and consult a neurosurgeon to help assess the current situation, mainly to determine the primary cause of the hydrocephalus, as targeted treatment can only be conducted once the cause is identified. For severe cases of hydrocephalus, surgery is generally recommended, and clinically, a ventriculoperitoneal shunt procedure is commonly chosen.
