This review describes the CT and MRI features of developmental variants and pathological lesions that involve the skull base, excluding those centered in the nasal cavity, nasopharynx, sinuses and orbits.
Normal anatomy of developing bony skull base will be illustrated. The lesions are categorized by pathology rather than locations, and the following entities will be covered.
Congenital and developmental lesions - arrested pneumatization, aberrant arachnoid granulations, dermoid/epidermoid cysts, ecchordosis physaliphora, encephaloceles, persistent craniopharyngeal canal
Inflammatory/Infectious lesions - skull base osteomyelitis, petrous apicitis, cholesterol granuloma
Benign lesions - Fibrous dysplasia, aneurysmal bone cyst, osteoma, osteochondroma, meningioma
Malignant lesions - Langerhans cell histiocytosis, lymphoma, neuroblastoma metastasis, Ewing’s sarcoma, osteosarcoma, chordoma, chondrosarcoma Read More

Faulty fetal packing is a concave depression of the skull caused in utero by external pressure (such as by the maternal pelvic bone, a fetal limb, or uterine fibroid). It has an incidence of approximately 1 in 10,000 births. Its main differential diagnosis is acquired ping-pong-type fracture of the malleable neonatal skull, which can raise suspicion for nonaccidental trauma if there is no history of accidental trauma. Most recent literature on faulty fetal packing describes only single case reports. This educational exhibit reviews a series of faulty fetal packing and neonatal calvarial fracture cases. After reviewing this educational exhibit, readers will be able to 1) describe the mechanism of faulty fetal packing, 2) describe the appearance of faulty fetal packing on multiple modalities including radiographs and CT, and 3) distinguish between prenatal faulty fetal packing, perinatal skull trauma, and neonatal accidental and non-accidental trauma.

To review the imaging appearance of the skull in hypophasphatasia (HPP). This pictorial review includes the serial imaging appearances, commencing from diagnosis, and throughout treatment with enzyme replacement therapy (ERT). The development of craniosynostosis is shown, as is the post surgical appearance following total cranial vault remodelling. Read More

Abnormal head shape is a common indication for imaging. While radiographs and ultrasound can play an important role, computed tomography is often the first imaging modality in the imaging work-up of abnormal head shape. It is important to understand the imaging appearance of normal sutures on each imaging modality and the normal progression of suture closure. The aim of this pictorial essay is to demonstrate the normal imaging appearance of the sutures on radiograph, ultrasound and computed tomography and to illustrate the features of the most common synostoses including single-suture craniosynostoses involving the metopic, sagittal and coronal sutures, and multi-suture craniosynostosis including Apert’s syndrome, Crouzon’s syndrome and Pfeiffer syndrome. In particular, we discuss the imaging work-up of multi-suture craniosynostosis including use of magnetic resonance imaging with an emphasis on pre- and post-operative imaging features and reporting tips.

Pediatric radiologists encounter a variety of focal skull lesions and often the diagnosis is not easy to achieve. The spectrum of the skull lesions in children is broad and encompasses pathologies that can be congenital, acquired, benign, malignant, infectious, or posttraumatic. The purpose of this exhibit is to review the imaging findings of both common and rare focal skull lesions in the pediatric age group. Read More

The purpose of this case report is to describe a rare case of epignathus (oral teratoma) with lateral skull base and intracranial extension. A 29-year-old G4P1122 female was referred to our institutuion after third trimester ultrasound and fetal MRI revealed a 34 week fetus with oral mass. There was extension intracranially through the lateral skull base. The complex mass showed cystic, solid, and fatty components. Polyhydramnios was also demonstrated. The prenatal imaging was crucial in planning the delivery of the fetus using EXIT procedure. Postnatal MRI Head and Neck, CT Head and Neck, CTA Head and Neck were helpful in guiding surgical resection of the oral, skull base, and intracranial mass. Emphasis will be made on the value of imaging to guide the management of this extremely difficult and rare case. Read More

The calvarium and overlying scalp is a uniquely changing entity in childhood that presents a dynamic source of pathologies in early life as the child grows and the sutures fuse. Various “lumps and bumps,” both symptomatic and not, may be discovered by the parents or detected by pediatricians. Although some may be diagnosed clinically, others may require imaging for diagnosis. Ultrasound offers a simple and often definitive alternative to CT and MRI for evaluation of calvarial lesions, avoiding unnecessary radiation and expense; however, it requires a sonologist with thorough understanding of the various calvarial and scalp entities. The purpose of this exhibit is to describe the progression of calvarial and scalp lesions encountered from the neonatal period through young adulthood. Read More
