"Turned out that’s not even a node. I guess it’s just calcified tissue?"
Hard to believe from my end, especially since there have been three different opinions on that. Still, it is possibly true, and is likely inconsequential.
"Also is 2.4 by 1.4 by 0.8 cm large? ... isn’t that long to short ratio bad?"
True, technically, it's less than 2 to 1. But I wouldn't think it's a hard and fast rule. Somewhere there might be a study that lists individual subject's data, and likely there are some that are less than 2 to 1 but are still benign.
Table 1 shows 16.8% of 'oval' nodes as being benign.
"...is having a little calcifies spot in soft tissue worrisome assuming it isn’t a node?"
I don't know but I doubt it.
"Table 1 shows 16.8% of 'oval' nodes as being benign."
Scratch 'oval', that should say 'round' instead.
Also from that table, S/L ratio ≥0.67 is benign in 35% of cases. Whereas your ratio is less round at only 0.58
And also a real, fungus infection called histoplasmosis. Are you in the Mississippi River Valley? Ohio River Valley? Neck nodes aren't common, but rarely can be: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4687211/
Then also TB, or a mycobacteria that is like TB but isn't TB.
Sarcoidosis and TB do both come to mind when there exists lung granulomas and cervical nodes. TB wasn't as common ~20 yrs ago as today, though.
Why did you have the CXR at 4 yrs old?
This probably increases the possibility that your neck nodes are granulomatous and less likely fibrosis. Or both. Your FNA mentioned neither, right? With this new info, probably a core needle would have been better - as it gets a core sample of tissue rather than just isolated cells.
