Meningioma project

Meningiomas are a common and important intracranial tumour, with many histological variant, some of which have quite specific imaging features. We thought that this cluster of articles and cases warranted review, as many subtype articles were missing, the main article (meningioma) was a bit disjointed, and many of the cases would benefit from a tidy up. This was a big project but has resulted in a much more comprehensive and polished section. 



Team: Bruno Di Muzio, Ahmed Abd RabouPiotr Gołofit, and Frank Gaillard

Expert adviser: David Yousem

Existing articles reviewed / improved: 16

New articles written: 20

Cases reviewed: 262


Existing articles reviewed / improved already had a number of articles in and around the meningioma topic cluster. Many, however, had been written years ago and had been built upon gradually. Sometimes a good clean up is required. 

Main article: meningioma

This is a long article and has been extensively edited and improved to improve not only the content but also the organization. Additional articles which have been reviewed and in almost all cases improved are: 

New articles written

Reviewing the topic also made us realise that we were missing a number of important entities. Specifically many of the histological subtypes, many of which have distinct biological behaviour and appearances, were missing.  

Cases reviewed / improved

It turns out we have a fair few cases of meningioma on the site. In fact at the time we started the project we had 262; that number has since no doubt increased. We did our best to go through and improve / tidy up most of them. We also removed a bunch of cases. Some were deleted, most which were not up to scratch were pushed back to draft mode

You can look through the most complete cases here

What's next?

We will of course be continuing to improve this content, but for now we will move onto new proposed editorial projects. If you are interested in helping out, you don't need to be an editor. Just write to and we'll get you started. 

Leave a commentNo comments on this post. and the American Society of Neuroradiology (ASNR)​ are collaborating on giving you all the opportunity to submit an adult brain case to ASNR 2016 Case of the Day. 

Each day during the  ASNR 54th Annual Meeting (May 23 - 26) in Washington a case will be shown as the official Case of the Day. This has traditionally been 'invite only', but this year one of the cases will be chosen from cases you submit to 

In addition to one ASNR 2016 case of the day winner, we will also be showcasing a number of the best submissions as our very own 'cases of the day' on our home page and through social media. And, even better, you will be contributing to your personal case library and making even better! 


There are a number of prizes available: 


The winner gets two awesome prizes:

  1. Standard Room for two (2) nights at the meeting venue at the Washington Marriott Wardman Park Hotel and including complimentary daily in room WiFi and health club access (value of US$590); prize courtesy of the American Society of Neuroradiology (ASNR). The reservation can be used at any point during the ASNR 54th Annual Meeting dates from Friday, May 20 through Thursday, May 26. If you are not planning to attend the conference, then that's ok. You will receive the prize either way, and you can, if you wish, transfer it. 
  2. The editoral team will also be giving the winner online access to our recent, and hugely popular, Adult Brain MRI review course and online access to our upcoming Neuroradiology Update 2016 course, scheduled in August  2016 (combined value (value of ~US$250).
Runner up

The editorial team will also be selecting a runner up who will be getting online access to our recent, and hugely popular, Adult Brain MRI review course and online access to our upcoming Neuroradiology Update 2016 course, scheduled in August  2016 (combined value of ~US$250).

Submitting a case

To make make your case eligible for the ASNR 2016 Case of the Day, simply upload an awesome Adult Brain case and add the tag ASNR2016 in the right hand column of the case edit page. 


Please make sure that your case is fully fleshed out (see our case publishing guidelines

Submitting a case is easy, and if you are not familiar this short video will help. 


Submissions close on February 14th 2016, and the winner will be chosen by ASNR committee in the following couple of weeks. The winner will then be contacted by email, so please make sure the email listed in your profile is correct. 


The winner will then be asked to take a few choice images from their case and make a two-slide powerpoint poster (Question / Answer) which will be shown at the actual conference. This is not an onerous task, and the template will be provided to you. Here is an example. 

A physical poster will also be be printed from your slides (by ASNR) and shown. This will be done for you, so if you are not attending, it is not a problem.  


If you have any questions, please write to

A little while back we added diagnostic certainty to our cases, so that you could more easily filter for cases that had an established diagnosis; we really want to ensure that grows not only in size but also quality. 

We had a little problem; we had over 20,000 existing cases that did not have a diagnostic certainty established. But that's ok, because we have an amazingly dedicated editorial team

So we started Operation Honey Badger in honour of this famous internet video meme and got cracking, not only adding diagnostic certainty, but generally improving cases, and removing those that were no longer of sufficiently high standard (see our current case publishing guidelines).

There has been stiff competition for the coveted title of overall honey badger (editor who has reviewed the most cases). 

Overall Honey Badger was Tim Luijkx with over 4,100 cases reviewed! Congratulations. 

Everyone pitched in, with many editors devoting many many many hours to the project. The result is that now (almost) all our cases have a diagnostic certainty. A huge step forward. 

Thank you all.

This personal story by Dr Ray Somcio, a pediatric radiology fellow at the Texas Children’s Hospital, beautifully shows how pediatric radiology saves lives.

I am a great believer in the use of social media in medicine. There really is no better way to bring continuing professional development into your day than by reading a few tweets, sharing some cases and having discussions with colleagues across the world.

If you are like many health professionals I meet, then you are probably intrigued by Twitter but are not quite sure where or how to begin. Well, luckily there is now a great little lecture series to help you flap your fledgling twitter wings!  

Radiologist Dr Jenny Hoang (@JennyKHoang) and pathologist Dr Sara Jiang (@Sara_Jiang) recently presented a Duke Medicine grand round exploring the use of Twitter in Medicine. Their three lectures are packed full of great tips. Take a look and I hope to meet some of you on Twitter soon.
