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). This entity presents as cysts of ependymal epithelial origin, probably arising by budding and separating from the embryonic central canal or early ventricular system and presenting as a space-occupying process. Shah N. Prenatal diagnosis of choroid plexus cyst: what next? Choroid plexus cysts (CPC) and echogenic intracardiac focus (EIF) are minor fetal structural changes commonly detected at the second-trimester morphology ultrasound. Patients with multiple intracranial cysts, especially when combined with agenesis of the corpus callosum, should be investigated for gene mutations, especially excluding OFD1 mutations. WebChoroid plexus tumors grow into the ventricles (fluid-filled spaces in the brain) from the cells that produce spinal fluid.
