Ultrasound and magnetic resonance imaging features of fetal intracranial cystic lesions: A pictorial essay

Abstract

This pictorial essay focuses on ultrasound (US) and magnetic resonance imaging (MRI) features of fetal intracranial cysts. Intracranial cysts are common findings in prenatal imaging, and if great attention is paid to their size, location, and imaging features, they can be diagnosed accurately. They are usually detected by fetal ultrasound exams. However, when ultrasound data on cystic lesion characteristics is insufficient, MRI and fetal neurosonogram are the best options for detecting other associated anomalies. The prognosis is highly dependent on their location and whether they are associated with other fetal anomalies.

Ultrasound and magnetic resonance imaging features of fetal urogenital anomalies: A pictorial essay

“…Also, MRI is frequently required for postnatal follow-up, particularly in situations with additional associated abnormalities. 3,4 In a retrospective study by Pico et al, MRI findings in combination with US follow-up complied with a postnatal diagnosis of urinary tract anomalies in 97% of cases, compared with 56% of cases with US examination alone. 5 In this article, we will discuss fetal urogenital anomalies, their causes, imaging features, prognosis, and possible treatments.…”

“…When ultrasonography is insufficient, restricted, or uncertain, MRI by professionals is a helpful option. Also, MRI is frequently required for postnatal follow‐up, particularly in situations with additional associated abnormalities 3,4 …”
