“…Huge cysts cause displacement but not destruction of the surrounding brain structures 13 (Figs 9A and B). The midsagittal view of the fetal brain is useful to correctly locate the small interhemispheric cysts, thus allowing to differentiate quadrigeminal cistern cysts, 14 cavum veli interpositi cysts 15 and suprasellar cysts 16 (Figs 10A to C). The differential diagnosis include: porencephalic cysts, schizencephaly, cystic tumors.…”

Most fetal brain anomalies can be diagnosed during the second trimester scan performed to screen for fetal malformations. However; there are some cerebral pathologies which become evident only during the late second and third trimester of pregnancy. Occupying space lesions, such as tumors, cysts, vascular malformations and hemorrhages frequently appear as late onset complications in a fetus diagnosed as normal during the second trimester anomaly scan.In this review paper the sonographic patterns of these anomalies will be described. Particular attention will be paid to the prognosis, which is extremely variable, ranging from the lethal outcome of huge brain tumors, to severe neurological handicap of severe hemorrhages or leukomalacic cysts, to normal postnatal outcome of some arachnoid cysts.

“…Antenatal ultrasound can identify arachnoid cysts as early as 20 weeks using a trans-abdominal probe and as early as 13 weeks from a trans-vaginal approach [4,20]. Ultrasonographic appearances are that of a homogenous and hypoechoic cystic structure with no internal flow on Doppler imaging [20].…”

“…This theory may hold more weight in secondary cysts, where blood or inflammatory products increase the osmotic properties of the fluid [8,14]. such as corpus callosal agenesis, colloid cysts, Rathke's cleft cysts, glioependymal cysts and craniopharyngiomas [20]. Karyotyping and MRI can be then considered to out-rule such associated anomalies.…”

Arachnoid cysts are benign, extra axial, cystic lesions, formed due to congenital splitting of the arachnoid layer. They are often discovered incidentally, either by fetal cranial ultrasound or as an asymptomatic finding on subsequent neuroimaging studies in adulthood. In this article, we present a pictorial review demonstrating the typical imaging features for arachnoid cysts and also include imaging appearances of more atypical arachnoid cysts and their potential complications. We also discuss the epidemiology, pathogenesis, imaging features, differential diagnosis and clinical presentation of arachnoid cysts according to their location and present a brief outline of treatment options.

“…The prognosis depends on the location, volume and growth of the cyst during the brain development. Differential diagnosis includes holoprosencephaly, porencephaly, choroid plexus cysts, and venous aneurysms (4)(5)(6)(7)(8).…”

OBJECTIVES: To analyze a rare triad of intracranial fetal pathologies and clinical study of the novel defi ned sequence pathogenesis based on prenatal and postmortem fi ndings. METHODS: Complex multidisciplinary clinical analysis and review of up-to-date literature. RESULTS: In an 18-gestational-week fetus the screening ultrasound scan resembled the semilobar type of holoprosencephaly and oral tumor. After the indicated termination of pregnancy, the histopathology results confi rmed another pathologies -oral meningoencephalocele, teratoma of the sellar area and large arachnoidal cyst of the anterior cerebral fossa. The surprising fi nal results were evaluated by specialists in prenatal diagnosis, histopathology, genetics, neurology, and radiology. CONCLUSION: We defi ned the fi nal diagnosed triad oral meningoencephalocele -intracranial sellar teratomaarachnoidal cyst as a novel sequence defect malformation. In the detailed sequence pathogenesis, the intracranial sellar teratoma created an aperture for meningoencephalocele in the cranial base and the arachnoidal cyst facilitated, by its growth and pressure, the protrusion of the brain tissues (Fig. 4, Ref. 10).
