Mastoid fontanelle approach for sonographic imaging of the neonatal brain

This pictorial review describes in detail the examination technique used to study the neonatal brain via the mastoid fontanelle and offers a panoramic view of the anatomical structures that can be identified in each US slice. The brain lesions are grouped as congenital malformations, haemorrhage, cerebellar lesions and sinus venous thrombosis. In each section, the additional information obtained through the mastoid fontanelle is provided. (orig.)
