[/INST] Hi, I had gone through your question and understand your concerns. A possible cause of irregular brain ventricles is a condition called Periventricular leukoplakia. It occurs likely as a result of hypoxic-ischemic lesions resulting from impaired perfusion of brain mainly in premature and low weight child Chat Doctor.  Other causes may be vasculitis, infection. So I suggest you to consult a Neurologist and discuss problems mentioned above. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. </s>
