Abstract

Prenatal diagnosis for alobar holoprosencephaly, is not difficult while for semilobar and lobar forms itmay be difficult. We present and discuss prenatal ultrasonographic and magnetic resonance imaging features of lobar holoprosencephaly in a 29 weeks-old fetus diagnosed prenatally. A nineteen years-old primigravid woman was referred with diagnosis of hydrocephalus. In ultrasonographic examination, lateral ventricles and cisterna magna were dilated, but absence of cavum septum pellucidum excluded the diagnosis of hydrocephalus. B mode examination of coronal and transverse sections of fetal brain revealed a cystic cavity of partly fused frontal horns between the two hemispheres in the anterior part of skull, and thalamic fusion. However, frontal horns were developed and discernible. Midline echo, lateral ventricles and third ventricle were observed. It was not possible to examine sagital planes of fetal brain by ultrasonography. Ultrasonographic diagnosis was lobar holoprosencephaly, which was then confirmed by fetal MRI. Ultrasonographic and MRI correlation was assessed. A detailed ultrasonographic evaluation is the primary examination method of obstetrician and it may help to diagnose and grade holoprosencephaly. Besides its correlation with prenatal MRI is good.

Özet

Alobar holoprosensefalinin (HPE) prenatal tanısı kolayca yapı-labilmekteysede, semilobar ve lobar formların teşhisi güçtür. Çalışmamızda 29 haftalık birfetusta prenatal ultrasonografi ve magnetic rezonans görüntülemesiyle tanı konulmuş bir lobar HPE'li fetusun bulguları sunulmuş ve tartışılmıştır. Ondokuz yaşında primigravid bir hasta hidrosefali tanısıyla kliniğimize refere edildi. Ultrasonografik muayenede lateral ventrikül ve sisterna magna dilate izlendi, fakat kavum septum pellusidu-mun olmaması hidrosefali tanısını ekarte ettirdi. Koronal ve transvers B mod ultrasonografik kesitlerde her iki hemiküre arasında frontal boynuzların birleşerek yaptığı kistik bir genişleme ve thalamik füzyon izlenmişti ancak frontal boynuzlar ayrı bir yapı olarak gözlemlenmekteydi. Orta hat eko, lateral ventrikül ve 3. ventrikül izlenebilmekteydi. Ultrasonographik olarak sagital kesit almak mümkün olmamıştı. Ultrasonografik olarak konulan lobar HPE tanısı daha sonar MRI ile doğrulandı. HPE tanısında ve derecelendirilmesinde, esas muayene yöntemi ultrasonografik yöntemdir. Ultrasonografinin MRI ile korelasyonu iyi derecededir.
