Board Review Cases – Pediatrics

This playlist is a collection of only the pediatric board review cases on this site. These cases are geared towards preparation for the radiology resident ABR core exam, although similar material is used for the ABR certifying exam general and neuroradiology sections as well as neuroradiology CAQ.

The format of this playlist is case-based. Each case consists of a series of images followed by 1 or 2 questions. The first question is usually to name the diagnosis, while the second is a multiple choice question to test deeper understanding of the specific condition. Try to get the diagnosis before you see the second questions.

 

Board Review 1 – Case 13

Neuroradiology board review. This lecture is geared towards the ABR core exam for residents, but it would be useful for review for the ABR certifying exam or certificate of added qualification (CAQ) exam for neuroradiology.

More description and the answer (spoiler!) are seen below the video.

This case shows a hyperdense mass in the left posterior nasal passages. There is expansion of the left sphenopalatine foramen. In a relatively young patient, there is really only one diagnostic consideration.

The diagnosis is: Juvenile nasal angiofibroma (JNA)

Juvenile nasal angiofibromas are masses that arise in the sphenopalatine foramen in young boys. They are extremely vascular lesions and are typically treated by embolization of branches of the external carotid artery which supply the mass prior to resection.

Board Review 1 – Case 12

Neuroradiology board review. This lecture is geared towards the ABR core exam for residents, but it would be useful for review for the ABR certifying exam or certificate of added qualification (CAQ) exam for neuroradiology.

More description and the answer (spoiler!) are seen below the video.

In this case, there are curvilinear calcifications which follow the cortex in the right cerebral hemisphere on CT. On MRI, there is atrophy of the right cerebral hemisphere with abnormal veins coursing through the deep white matter of the right cerebral hemisphere. On contrast enhanced images, there is avid enhancement of the right hemisphere leptomeninges.

The diagnosis is: Sturge-Weber syndrome

Sturge-Weber syndrome is a variant in which normal cortical vessels fail to form, and the hemisphere is drained by abnormal mesenchymal veins which course through the cerebral hemisphere. Classic imaging findings include cortical calcifications of one hemisphere.
