Atretic cephalocele is a rare disruption of neural tube closure. The reported incidence ranges from 1 in 3500 to 1 in 5000 live births. Is a small subscalp lesion that consist of dura, fibrous tissue, and dysplastic brain tissue. Its most common presentation it is a palpable midline parietal soft tissue mass, occasionally occipital, with a wide range of clinical presentations, the patient may have normal neurological development or have severe mental retardations, since it could be associated with multiple intracranial malformations including a fenestrated superior sagittal sinus (the most common), persistent falcine sinus, vertical embryonic positioning of the straight sinus, holoprosencephaly, hydrocephalus, eye anomalies, agenesis of the corpus callosum, among others, therefore is important to know about this condition as well as to identify its radiological characteristics using different diagnostic imaging methods to make a certain diagnostic. Transfontanellar brain ultrasound could be used as the first imaging method as it enables a non-invasive method, in addition the patients are not exposed to ionizing radiation, being the most consistent finding a subcutaneous, hypoechoic mass, with a solid fibrous tract connecting the extracranial lesion, through a small bony cranium defect, to the intracranial space; additionally in order to evaluate a further extension of the fibrous tract or the presence of other anomalies, CT or MRI can be performed, considering to the MRI as a better study because it can be used in pediatric population since there is no exposure to radiation. Main differential diagnoses of atretic cephalocele are sinus pericranii and dermoid cyst, other possible causes include haemangioma, sebaceous cyst, inclusion cyst, lipoma, tumors (Langerhans cell histiocytosis, sarcomas, etc.), bone and soft tissue infections and traumatic lesions. This educational poster pretends to review the radiological findings of two cases of patients with atretic cephalocele moreover a literature review since the published works regarding is limited and few case series or case reports have been documented.

Pediatric facial and scalp lesions are a common indication for imaging. Ultrasound is often the first imaging modality in the work-up of these lesions. While many soft-tissue lesions are nonspecific on ultrasound, there are several which have a characteristic sonographic appearance, including pseudotumors such as asymmetric buccal fat pads and fat necrosis, vascular lesions such as infantile hemangioma and venous malformations, scalp lesions such as cephalohematoma and subgaleal fluid collection and other lesions including dermoid cysts and pilomatricoma. Prompt recognition of these lesions can reduce unnecessary further investigations and improve timely diagnosis and management. The aim of this pictorial essay is to demonstrate the characteristic sonographic appearances of the most common pediatric facial and scalp lesions with computed tomography and magnetic resonance imaging correlation where appropriate to aid in narrowing the differential diagnosis and if warranted direct subspecialty referral.
