Neonatal cranial sonography: A concise review for clinicians.

Gupta P, Sodhi KS, Saxena AK, Khandelwal N, Singhi P - J Pediatr Neurosci (2016 Jan-Mar)

Bottom Line: Cranial sonography has highest impact in neonates suspected to have meningitis and its complications; perinatal ischemia particularly periventricular leukomalacia (PVL); hydrocephalus resulting from multitude of causes and hemorrhage.Approach to cranial sonography involves knowledge of the normal developmental anatomy of brain parenchyma for correct interpretation.Correct technique, taking advantage of multiple sonographic windows and variable frequencies of the ultrasound probes allows a detailed and comprehensive examination of brain parenchyma.

ABSTRACT
Cranial sonography continues to hold an important place in neonatal care. Attributes favorable to sonography that make it almost indispensable for routine care of the newborn includes easy access, low cost, portability, lack of ionizing radiations and exemption from sedation or anaesthesia. Cranial sonography has highest impact in neonates suspected to have meningitis and its complications; perinatal ischemia particularly periventricular leukomalacia (PVL); hydrocephalus resulting from multitude of causes and hemorrhage. Not withstanding this, cranial sonography has yielded results for a repertoire of indications. Approach to cranial sonography involves knowledge of the normal developmental anatomy of brain parenchyma for correct interpretation. Correct technique, taking advantage of multiple sonographic windows and variable frequencies of the ultrasound probes allows a detailed and comprehensive examination of brain parenchyma. In this review, we discuss the technique, normal and variant anatomy as well as disease entities of neonatal cranial sonography.

Intracranial hemorrhage (a) sagittal image shows the typical appearance of germinal matrix hemorrhage as echogenic focus in the caudo-thalamic groove. C: Caudate; TH: Thalamus. (b) Intraventricular hemorrhage is seen on this coronal image as echogenic contents within the frontal horn with layering (arrows). (c) Coronal image demonstrates bilateral temporoparietal echogenic lesions (arrows) suggestive of intraparenchymal hemorrhage. Also note mild mid-line shift towards left side

Figure 9: Intracranial hemorrhage (a) sagittal image shows the typical appearance of germinal matrix hemorrhage as echogenic focus in the caudo-thalamic groove. C: Caudate; TH: Thalamus. (b) Intraventricular hemorrhage is seen on this coronal image as echogenic contents within the frontal horn with layering (arrows). (c) Coronal image demonstrates bilateral temporoparietal echogenic lesions (arrows) suggestive of intraparenchymal hemorrhage. Also note mild mid-line shift towards left side

Mentions: Most common site of hemorrhage in preterm neonates is a germinal matrix.[13] This is noted as echogenic areas in the caudothalamic groove [Figure 9a]. The hemorrhage can extend into the ventricles [Figure 9b] or into the parenchyma [Figure 9c], former resulting in hydrocephalus.
