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
