Akrani'nin intrauterin ultrasonografi bulguları: Olgu sunumu

Akrani (eksensefali) beyin dokusunun hemen hemen tama yakın gelişmesine rağmen kraniyumun bir kısmının ya da tamamının gelişmemesi ile karakterize nadir bir gelişimsel anomalidir. Akrani anensefaliden sonografik olarak beyin dokusunun varlığı ile ayırt edilir. Bu yazımızda transabdominal ultrason ile 14.-15. haftalarda saptanan 2 akrani olgusu sunduk ve akrani ile anensefalinin ultrason bulgularını tartıştık.

Case report: Intrauterin sonographic findings of acrania

Acrania (exencephaly) is a rare developmental abnormality characterized by partial or complete absence of the cranium with nearly complete development of brain tissue. Acrania can be differentiated sonographically from anencephaly by the presence of cortical brain tissue. We report two cases of acrania which are detected by transabdominal sonography in the 14th-15th weeks of gestation and sonographic findings of acrania and anencephaly are discussed
