Board Review 1 – Case 20

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 CT of the orbits with proptosis and enlargement of the extraocular muscles. There is relative sparing of the myotendinous junction (where the muscles meet the globe).

The diagnosis is: Graves ophthalmopathy

Graves disease is one of the most common causes of bilateral opthalmopathy, although findings do not have to be symmetric. Findings often do not improve with treatment of Graves disease.
