Although head ultrasound (HUS) is most often used in the neonatal intensive care unit (NICU) setting as a screening exam for emergencies such as hydrocephalus, intracranial hemorrhage, and ischemic injury, a spectrum of congenital brain abnormalities may also be diagnosed, especially with state-of-the-art US technology that enables detection of more subtle malformations.

While brain MRI remains the gold standard for comprehensive evaluation of congenital CNS anomalies, knowledge of the appearance of such pathologies on HUS is vital: HUS is often the first exam performed, and some infants are too critically ill to undergo MRI. Identification of congenital anomalies by the radiologist may generate prognostic information that can impact critical medical decision-making and patient/family counseling in the NICU.

The goals of this educational poster are to provide a systematic approach to evaluating congenital brain anomalies on HUS and illustrate the ultrasound appearance of common and less common congenital abnormalities with MRI comparisons, as well as highlight potential pitfalls in making these diagnoses.

Covered entities include:
Posterior fossa malformations: e.g., Chiari II, Dandy-Walker
Midline anomalies: e.g., Holoprosencencephaly, agenesis of the corpus callosum, pericallosal lipoma
Cortical malformations: e.g., Gray matter heterotopia, schizencephaly, lissencephaly
Vascular malformations: e.g., Vein of Galen malformation
Congenital infections: e.g., Congenital cytomegalovirus Read More

Abnormalities of the portal venous system are a heterogenous group which include congenital anomalies and changes in portal vein secondary to iatrogenic causes or inflammatory and neoplastic conditions. Detailed knowledge of the normal embryology, anatomy of the portal vein and its variants is crucial in the understanding of portal vein anomalies. Identification of normal or variant portal vein anatomy is important part of pre surgical and pre liver transplant evaluation and helps minimize post-surgical/interventional complications. Read More
