Board Review 2 – Full lecture

Posted on by Brent Weinberg, MD

Board Review 2 – Full lecture

This lecture is a board review lecture geared towards preparation for the radiology resident ABR core exam, although similar material is used for the ABR certifying exam general and neuroradiology sections.

The format of this lecture 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.

These are all general neuroradiology questions.

Board Review 2 – Case 5

Posted on by Brent Weinberg, MD

Board Review 2 – Case 5

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 patient with headache. Images are from an MR angiogram of the neck. The first few images show absence of filling of the left vertebral artery. This could theoretically be from atherosclerotic disease or thrombosis, but there is filling on a contrast enhanced MRA of the neck. This is because the flow in the vertebral artery is reversed in the setting of occlusion of the proximal subclavian artery.

The diagnosis is: subclavian steal

Board Review 2 – Case 4

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 an older woman with hyperdensity in the basal ganglia and cerebellar hemispheres on CT. The abnormality on MRI is T1 hypointense and has susceptibility artifact. The findings are most consistent with abnormal calcium deposition.

The diagnosis is: idiopathic basal ganglia calcification (Fahr disease)

There are a number of causes of calcification in the brain, some secondary (hyperparathyroidism) and this disease, which is a familial condition.

Board Review 2 – Case 3

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 patient with a coagulation disorder and new neurologic symptoms. FLAIR images show hyperintensity in the right transverse and sigmoid sinus. The abnormality is confirmed on magnetic resonance venogram, which shows absence of flow in that region. There is a filling defect on postcontrast imaging.

The diagnosis is: dural sinus thrombosis

Board Review 2 – Case 2

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 patient with hearing loss some thickening of the bone in the external auditory canals. It is bilaterally symmetric and causes severe EAC narrowing.

The diagnosis is: surfer’s ear, or exostosis of the external auditory canal.

Board Review 2 – Case 1

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 is a mass in the right cerebellopontine angle and internal auditory canal. The differential for these masses includes schwannoma, meningioma, arachnoid cyst, and epidermoid. The key to differentiating this mass from others are that it is solid, centered in the internal auditory canal, and has a few areas of cystic degeneration or necrosis.

The diagnosis is: vestibular schwannoma

Imaging brain tumors – 6 – Common imaging scenarios

Imaging brain tumors – 6 – Common imaging scenarios

Brain tumors are one of the most common diagnoses addressed in neuroradiology. This covers a wide spectrum of disease, from primary brain tumors like gliomas and glioblastomas to secondary disease like metastases. This lecture covers the spectrum of the most common brain tumors, with an emphasis on primary brain tumors.

This video discusses different scenarios you may encounter when imaging, such as a solitary enhancing lesion, multiple enhancing lesions, and non-enhancing peripheral lesions. Each of these has a differential diagnosis, and choosing appropriately can help guide therapy.

Additional videos in the playlist will address the imaging findings of brain tumors, such as astrocytomas,oligodendrogliomas, other low grade glial tumors,and non-glial tumors. Other videos address general topics in brain tumor imaging, and some challenge cases to apply your skills.

The level of this lecture is appropriate for radiology residents, radiology fellows, and trainees in other specialties who have an interest in neuroradiology or may see patients with brain tumors.

Imaging brain tumors – 7 – Bonus cases

Brain tumors are one of the most common diagnoses addressed in neuroradiology. This covers a wide spectrum of disease, from primary brain tumors like gliomas and glioblastomas to secondary disease like metastases. This lecture covers the spectrum of the most common brain tumors, with an emphasis on primary brain tumors.

This video gives some additional cases in which you can apply the principles learned in the other videos to form a differential. These are challenging cases, and your top differential will not always be correct, but it is more about going through the thought process.

If you have not seen the other brain tumor videos, it may be useful to check them out before watching this video. They address imaging tumor types including astrocytomas,oligodendrogliomas, other low grade glial tumors,and non-glial tumors. Other videos address general topics in brain tumor imagingand how to form a differential diagnosis for a brain tumor.

The level of this lecture is appropriate for radiology residents, radiology fellows, and trainees in other specialties who have an interest in neuroradiology or may see patients with brain tumors.

Imaging brain tumors – 5 – Non glial tumors

Imaging brain tumors – 5 – Non glial tumors

Brain tumors are one of the most common diagnoses addressed in neuroradiology. This covers a wide spectrum of disease, from primary brain tumors like gliomas and glioblastomas to secondary disease like metastases. This lecture covers the spectrum of the most common brain tumors, with an emphasis on primary brain tumors.

This video discusses imaging of common non-glial brain tumors, such as lymphoma, metastasis, and meningioma. Lymphoma is a common brain tumor which can be either associated with systemic lymphoma or more commonly confined to the brain (primary central nervous system, CNS, lymphoma). It is associated with immunosuppression and HIV. Metastatic disease is also common, and it’s important to remember that up to 50% of intracranial metastases are solitary. Meningiomas are the most common brain tumors overall and are extra-axial lesions. They come in 3 grades, and grade 2 and 3 are often irradiated after resection.

Additional videos in the playlist will address the imaging findings of other types of brain tumors, such as astrocytomas,oligodendrogliomas, and other low grade glial tumors. Other videos address general topics in brain tumor imaging, how to form a differential diagnosis for a brain tumor, and some challenge cases to apply your skills.

The level of this lecture is appropriate for radiology residents, radiology fellows, and trainees in other specialties who have an interest in neuroradiology or may see patients with brain tumors.
