Editor's Notes

  1. Early - Grey and white matter involvement; cortical and deep grey involved; some brain swelling and probable secondary engorgement of the leptomeninges. MRA shows more dilated vessels ipsilaterally with increased CBF. Not sure what to make of the ‘blob’ on what looks like an SWI slab – perhaps fewer veins on the ipsilateral side. Late: Most atrophy in the cortical and subcortical WM regions, but deep grey is affected too.

  5. Arterial Ischemic Stroke - 3 phases on the same images Sicklers have multiple risk factors for stroke – including underlying arteriopathy &amp; prothombotic tendency; chest crises and hypoxia
  6. Meningitis with venous infarcts:
  7. H Simplex – F10y, HSV by DNA in CSF on PCR
  8. 11 yo HSV
  9. “Stroke not confined to a vascular territory” Keywords: MELAS, mitochondrial disorder Findings: f/u ct with new, extensive wm and cortical hypodensities c/w new infarcts and possibly some are the result of recent sz&amp;apos;s Narrative: H/o delayed development beginning at age 7. 2 yrs ago, transient vis loss and dizziness which resolved after several days (no work up done). Approx 3 days prior to this MRI, pt experienced visual sx again, as well as aphasia. On physical exam, rt visual field cut. Since admission, visual complaints and aphasia are significantly improved. CSF w/no WBC&amp;lt; mildly incr pro = 70, nl glu. Serum lactate normal. Repeat serum lactate pending. Pt also with h/o central heaaring loss. Clinical as well as imaging findings are consistent w/MELAS.

  12. Early - Grey and white matter involvement; cortical and deep grey involved; some brain swelling and probable secondary engorgement of the leptomeninges. MRA shows more dilated vessels ipsilaterally with increased CBF. Not sure what to make of the ‘blob’ on what looks like an SWI slab – perhaps fewer veins on the ipsilateral side. Late: Most atrophy in the cortical and subcortical WM regions, but deep grey is affected too.
  13. Expansion of the splenium, T2 hyperintense signal, mild patchyenhancement, mildly reduced on ADC if at all Splenial lesion with mass effect and patchy enhancement. Seizure presentation but otherwise relatively mild clinical onset. Gets worse over a few months on steroids with a vasogenic pattern of oedema, before resolving over a matter of years. I think I can see a surgical scar in the scalp indicating a biopsy
  14. Case 3:Splenial lesion with mass effect and patchy enhancement. Seizure presentation but otherwise relatively mild clinical onset. Gets worse over a few months on steroids with a vasogenic pattern of oedema, before resolving over a matter of years. I think I can see a surgical scar in the scalp indicating a biopsy (?).Diagnosis:A: Unlikely to recover so wellB: My favoured option. Need to look for clues (subtle lesions) elsewhereC: Reasonable thought for adults. OK for location and enhancement. Unlikely in kids in my experienceD: Great for location, not sure about enhancement. Another reasonable thought for adult, but unlikely in kids.E: Typically subcortical and shouldn&amp;apos;t enhance.
  15. Biopsy tract, worsening up to 4 months. At 5 years, evolution to gliosis and volume loss.

  27. Not quite sure what the dominant feature on the T2w image is - white matter disease or dark thalamus sign??Possibly kinky vessels on MRA. Lactate on MRS.Diagnosis:A: white matter too bright on T2 and I can see mature myelination in the PLIC, which should not happen in PMDB: Capsular white matter too well preserved for this.C: PLIC not affectedD: Does give you kinky vessels, WM disease and can have raised lactates.E: OK for white matter disease and raised lactate, but the vessel tortuosity is typically in the basal ganglia perforators.On balance, &amp;apos;D&amp;apos; is a better fit for me than E.
