CLIPPERS or SLIPPERS?

I was recently contacted by someone with a close relative who had been diagnosed with possible "SLIPPERS" syndrome. I initially suspected a typo but then realised that this was a CLIPPERS variant which had passed me by. Initially proposed by Dr Armand in 2015 this condition differs from CLIPPERS in which part of the brain is predominantly affected. In CLIPPERS the enhancing lesions seen in MRI are concentrated below the Tentorium (see image above). In SLIPPERS (Supratentorial Lymphocytic Inflammation with Parenchymal Perivascular Enhancement Responsive to Steroids) the lesions are concentrated above the Tentorium. The two patients in the original case-study both responded to treatment similarly to CLIPPERS but had presented with seizures and headaches respectively which I think are less common in CLIPPERS. Another patient was subsequently reported by Dr Horng in 2017 who also responded to similar treatment. It's unclear to me whether this is really a distinct syndrome or just a variant of CLIPPERS but at least the treatment response is very similar so the difference for treatment purposes is not crucial (it would seem - I'm not  a doctor).

In other news my medication (Azathioprine) is mysteriously unobtainable in my locale currently for reasons unknown to me. Is it a manufacturing problem, supply problem, hoarding problem? I don't know but it's been suggested I ask my doctor for an alternative - may be easier said than done as, having been stable for quite a few years, changing meds at this stage is not on my agenda. There was a shortage a few years ago which resolved after a few weeks so hopefully the same thing will happen again.
