Most cases of bilateral ventricular widening on imaging after hydrocephalus surgery are due to primary hydrocephalus. If it is new after surgery, it may be due to the reoccurrence of abnormal cerebrospinal fluid circulation.
CT and MRI are the main and reliable methods of diagnosing hydrocephalus and help to clarify the cause and classification of the disease. Although there are various types of hydrocephalus, regardless of the type of hydrocephalus, there are varying degrees of enlargement or widening of the ventricles and cerebral pools when the above imaging tests are performed. Additionally the enlargement of the third ventricle is more pronounced when hydrocephalus is present.
Bilateral ventricular widening on post-surgical imaging is mostly due to primary hydrocephalus prior to surgery, and surgery may slow down the manifestation of widening to some extent. In the case of new onset of bilateral ventricular widening after surgery, it is necessary to be alert to the emergence of new cerebrospinal fluid circulation disorders after surgery, which in turn leads to hydrocephalus, and it is necessary to compare with the previous findings and analyze them comprehensively.
With the symptoms of hydrocephalus or bilateral ventricular widening, it is recommended to go to the hospital in time for consultation and active treatment under the doctor’s guidance.
