Título

Ultrasonography and Fetal Magnetic Resonance Imaging of the AVID Imaging Triad

Introdução e objetivo(s)

In prenatal screenings, the AVID spectrum (asymmetric ventriculomegaly, interhemispheric cyst, and dysgenesis of the corpus callosum), collectively visualized as an imaging triad, is a rare cerebral anomaly. The primary objective is to emphasize the importance of early detection through ultrasound (US) and fetal magnetic resonance imaging (MRI) for precise diagnosis.

Método(s)

Cases were selected based on the characteristics of the imaging triad, evaluated through fetal MRI and obstetric ultrasound between weeks 27 and 35 of gestation.

Discussão

Increased expertise and advancements in technology have significantly improved the capacity to identify these anomalies, though it remains a radiological diagnostic challenge. Each element may manifest independently or collectively, exhibiting distinctive clinical and imaging characteristics. Additionally, emphasis is placed on the significance of taking the AVID triad into account, given its variable prognosis and association with neurodevelopmental delays, leading to the necessity of cerebrospinal fluid shunt neurosurgery in the majority of cases.

Conclusões

It is a rare cerebral anomaly that can cause significant neurological problems and developmental delays. Fetal US and MRI play a crucial role in visualizing relevant defects and ruling out others. Treatment of these conditions involves substantial supportive measures, with surgical intervention and early intervention therapy forming the basis of treatment.
