The Differential Diagnosis of Fetal Intracranial Cystic Lesions

Fetal Intracranial cysts can be diagnosed during pregnancy by the use of ultrasound scan. The cysts can be found in different brain compartments and may be of diverse origins. Choroid plexus and arachnoid cysts are the most commonly diagnosed lesions and when isolated carry a good prognosis. Intraparenchymal cysts may have different etiologies, and the prognosis depends largely on the location and the extent of the lesion.
