In the second trimester, the size of choroid plexus cysts that are of clinical significance is debatable. According to some neurosurgeons, the approach to all expansive intracranial cysts, whether developmental or acquired such as posthemorrhagic cysts, can be sufficient through a small burr hole and fenestration of the cyst through a rigid neuroendoscope, with minimal risk of complications and good results on size of the cyst (71).
