Dandy-Walker Malformation: Prenatal sonographic diagnosis

Konstantinos Zacharis, Stavros Kravvaritis, Anastasia Papakonstantinou, Theodoros Charitos, Eleni Chrysafopoulou, Anastasia Fouka

The Dandy-Walker malformation is a rare congenital intracranial malformation that comprises of complete or partial agenesis of the cerebellar vermis, cystic dilatation of the 4th ventricle and an enlarged posterior fossa. Here we report a case of Dandy-Walker malformation detected incidentally during a routine fetal sonographic examination at 18 weeks of gestation. The couple decided termination of pregnancy, after adequate genetic counseling. Detailed postmortem examination revealed correlation between prenatal sonographic imaging and histopathological findings. This case report indicates the fact that fetal magnetic resonance imaging may not be necessary in diagnosis, especially when pregnancy termination is preferred.

Prenatal diagnosis of a large suprasellar arachnoid cyst

George Asimakopoulos, Panagiotis Antsaklis, Mariana Theodora, Michael Sindos, Alexandros Rodolakis, Dimitrios Loutradis, George Daskalakis

Arachnoid cysts represent 1% of all intracranial lesions and appear on the arachnoid membrane (subarachnoid space). The etiology and pathogenesis of arachnoid cysts remain unclear and in their majority they are asymptomatic. Due to the developmental origin of arachnoid cysts, these formations can be identified on prenatal fetal imaging. In this report we presented a case of an enlarged suprasellar arachnoid cyst detected incidentally during a routine fetal sonographic examination at 33 weeks of gestation …

What the Gynecologist expect from Ultrasounds

Antonios Koutras, Nikolaos Thomakos, Panagiotis Antsaklis, Aris Antsaklis, Dimitrios Loutradis

Diagnostic medical ultrasound was first developed in the 1960s but it did not become part of routine clinical practice until the late 1970s. TVUS was introduced in the 1980s and it has expanded rapidly because of the improved quality of pelvic imaging provided bu high frequency transducers (5-7 Hz). It is generally accepted that ultrasound is the most important and primary tool in Gynecology. It represents essential part of the diagnostic process in examining the female pelvis and the first investigation for the majority of relative symptoms. Emphasis must be given in how to maximize image quality and how to recognize normal and pathologic features…

Maternal Klippel – Trenaunay syndrome with complete hydatidiform mole and coexistent fetus: A case managed by surgical evacuation with review of literaturee

Ahmed Samy El-Agwany

Introduction: Klippel-Trenaunay Syndrome (KTS) is a rare triad of congenital vascular malformations involving extensive Port wine stains, soft tissue or bone hypertrophy and underlying venous and/or lymphatic malformation affecting limb, pelvic or abdominal organs. Pregnancies with a hydatidiform mole and a live fetus are extremely rare …

Ultrasound examinations in low risk pregnancies

Pilalis A, Souka A, Kassanos D

The scope of this article was to propose an updated protocol for the routine ultrasound examinations in low risk pregnancy. The protocol presents the requirements for the examiner (training, continuing education, data collection and storage) and analyses the mandated sonographic views. In addition, we review the literature on the sensitivity of ultrasound in the detection of fetal anomalies …

Determining strategy of the non-invasive prenatal screening for chromosomal defects

Xiromeritis PN, Tsapanos VS

The need to reduce the rate of invasive screening (chorionic villous sampling, amniocentesis), and to detect the high risk pregnancies for chromosomal anomalies as early as possible, led to the concept of the sequential non-invasive screening, based on the Bayes theorem. The numerous non-invasive screening tests for chromosomal defects, should provide the calculation …
