ASNR 50th annual meeting, 21-26 April 2012, New York, NY, USA.

I had the privilege of attending, and delivering an oral presentation (Mild congenital external and middle ear malformations: Identifying the subtle findings) at, the 50th meeting of the American Society of Neuroradiology (ASNR) in New York this year. It was a most prestigious and well-attended meeting, with many simultaneous presentations and lectures on various topics of interest on all aspects of neuroradiology.

One particularly important topic was the assessment of true progression and pseudoprogression in the age of anti-angiogenic therapies. The Revised Assessment in Neuro-Oncology (RANO) criteria is the latest, albeit imperfect, system to address this issue. Radiologists are advised to report their neuro-oncology imaging studies according to the RANO criteria. It is also important to be aware of the drastic changes in the imaging appearance of brain tumours that may result within 24 hours after the administration of anti-angiogenic therapies such as bevacizumab (Avastin).

Another topic of interest was the imaging of human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma. This is an increasingly recognised entity, often affecting younger patients without traditional risk factors such as smoking and alcohol use. It is, however, associated with certain sexual practices. These tumours appear to have a better prognosis than conventional oropharyngeal squamous cell carcinomas.

The educational exhibitions, electronic posters and cases of the day were also highly interesting, and I encourage South African residents and radiologists to consider submitting their research or educational projects to international meetings such as that of the ASNR.

I express my gratitude to the RSSA, who awarded me an educational grant to attend the ASNR and to present my research.
