ANOMAL OR DELAYED DEVELOPMENT OF THE POSTERIOR MEMBRANOSAL REGION OF THE BRAIN: ANATOMY, ULTRASOUND DIAGNOSTICS, NATURAL COURSE AND OUTCOME OF BLAKE POCKET CYST IN THE FETAL.
Keywords:
We decided to review the main documents on the normal and abnormal development of PMA in order to clarify the origin of BOD in as much detail as possible. Having done this, we aimed to determine sonographically acceptable criteria for its diagnosis and to review our experience in diagnosing fetal cerebral palsy.Abstract
Blake's pouch cyst (BPC) is considered a pathological lesion resulting from abnormal development of the posterior membranous area (PMA) of the fetal brain. However, although its first description dates back to 1900, there is little evidence of this anomaly in the literature: less than 10 articles have been published on the postnatal appearance of cerebral palsy in infants and adults. Although cystic posterior fossa malformations are one of the most frequently discussed topics in fetal neurology, we have found very few series addressing fetal cerebral palsy from a diagnostic or clinical perspective, the only exception being pathology studies9 and a couple of other interesting articles10. 11, one of which included the initial diagnostic determination of BOD10.
