Hi. Thanks for using Health Care Magic.
Some times on CT scan
, you can come across calcifications. Such benign calcifications are calcified graulomas and considered to be normal healing process in brain after any minor infection. No further treatment and tests is required for these calcified granuloma
and they will remain there without any problem for your mother.
I can tell with certainty that there is no relation between her left knee joint pain and the calcified granuloma of brain. Her left knee pain
will more likely be due to Oseoarthritis.
She will need an x ray
of the knee to confirm this.
So be ressured
Hope this answers your query.
Thanks and Regards
