1 FETAL HEAD ABNORMALITIES • Cranial vault (skull) defects • Cranial Vault & Skull Defects (The Calvarium) • Absence of Bone: Acrania and anencephaly • Cranial Openings: Cephaloceles • Abnormal Skull Shapes: lemon sign the strawberry skull and the cloverleaf skull • Look for images with the following abnormalities • You are free to look at the internet or on the PACS in the clinical department. Please reference your sources well. • Put an ultrasound image of the normal and then show the abnormality listed • Describe each abnormality; explain what is different from the normal, including what causes it • What can be done to prevent such an abnormality (e.g., educate pregnant women to refrain from alcohol consumption) • What ultrasonographers must watch out for when scanning. Description This is a group assignment. All members are expected to contribute to the ultimate product that will be presented in class on the 19th October. Each group will have 15 minutes to present. additional 5 minutes will be for questions or any clarification that might be needed. we are 5 group members

This guide covers essential aspects of fetal head assessment, starting with the establishment of normal cranial anatomy and ossification patterns through ultrasound. It then compares major skull abnormalities, including acrania, anencephaly, and cephalocele, highlighting key signs like the lemon sign. Finally, it emphasizes the importance of prevention strategies, including preconception counseling, folic acid intake, and avoiding teratogens to promote healthy fetal development.
