There's a huge list of horseshit peddled to people with autism (or more usually their parents).

If a significant number of normal and autistic children/adults were scanned more of a matter of course (much like mammograms), then we might actually have better knowledge and improve real world treatment.
---- Edit for clarity
I understand that the sheer usage of mammograms has actually been shown to be a poor predictor in practice, the brain is a bit more complicated, and scanning/evaluating would take more practice... but the impact to society could be very large, indeed.
Submitted article doesn't talk about this research, but talks about use of MRI for their own pet theory.

The scams you mention are even discussed in the article. Did you read it? Or are you saying that MRIs are like chelation therapy?
As you can see, the linked article concerns treating intracranial cerebrospinal fluid cysts when treating hydrocephalus (and is effective as far as I know). Now: what does this treatment have to do with the cyst presented in the original blog? The purpose of the shunt in your link is to allow venting of cerebrospinal fluid. Is the cb-fluid flow somehow blocked in the case of the autistic brother in the blog or is the cyst located in a place where shunting does not make any sense?
And to your earlier point, that SpringerLink article shows that they've been draining such cysts with shunts since at least as early as 1985, even if they didn't necessarily know what leaving them in place might result in later in life.
