||Arachnoid cysts are collections of cerebrospinal fluid developed within the arachnoid. The arachnoid cyst of the
posterior fossa is sometimes responsible for neurological, motor, severe and irreversible disorders.
We report a case of an arachnoid retro cerebellar cyst’s antenatal diagnosis on a fetus during an ultrasound
performed at 33 WG and confirmed by a MRI at day of life. Treatment consisted of ventriculoperitoneal Shunt at six
months of life with immediate decrease of the cyst volume. The eleven-month control found a complete resorption of
the arachnoid cyst but a minor psychomotor retardation. It results that the prognosis is mainly related to the
presence of associated lesions whose research requires the availability of magnetic resonance imaging.
