Introduction: We report the rare finding of recurrent periventricular pseudocysts (PVPC) in consecutive pregnancies in 4 families and their postnatal outcome.
Materials and methods: We reviewed the databases of 3 large ultrasound units searching for the diagnosis of PVPC in 2 pregnancies of the same patient.
Results: The first case of recurrent PVPC was diagnosed in 2011 and since then 3 additional families were diagnosed (8 cases of PVPC all in all). All fetuses underwent fetal MRI that confirmed the presence of frontal or frontocaudal PVPC. Amniocentesis, when performed, demonstrated a normal karyotype. Termination of pregnancy was carried out in 2 pregnancies in 2 of 4 families. The remaining 6 pregnancies ended with a term delivery, and to date all babies are developing normally.
Conclusion: The rare finding of recurrent brain PVPC in consecutive pregnancies raises the possibility of a hereditary etiology as opposed to a sporadic event. As in isolated PVPC, frontocaudal 'familial PVPC' appears to carry a favorable prognosis.
