For the phenomenon of bilateral frontotemporal subarachnoid widening in babies, it may be physiological widening firstly, which is caused by the uneven development of brain tissues and skull bones of babies in this age group. Physiological widening usually doesn’t need any treatment, and will disappear gradually with the balance of development.
