I just wanted to share an article that was recently posted to our Facebook group on ME/CFS and structural diagnoses. A woman in it who meets ME/CFS criteria was recently diagnosed with bilateral internal jugular vein stenosis (IJVS). This is considered a congenital condition, however she never had symptoms before contracting Dengue Fever. Her doctor hypothesizes that since Dengue Fever can thicken the blood, her infection took a previously asymptomatic congenital condition and made it symptomatic. This hypothesis is supported by the fact that a drug called Stugeron, a vasodilator, improves her symptoms.
IJVS, as this article describes, can cause symptoms that “mimic” intracranial hypertension including altered CSF flow and cerebral hypoperfusion:

This pings for me given the conversation in another thread about how there might be a range of diagnoses that can cause intracranial hypertension and/or cerebral hypoperfusion, resulting in ME/CFS symptoms.
It also pings for me as it is an example of a concept I keep encountering: that there are patients who have a congenital, anatomical abnormality that prior to an infection, is completely and largely asymptomatic, and that only becomes apparent after a major inflammatory event. That was the case for me with tethered cord syndrome and, apparently, in this patient with IJVS.
