Hey Vipul,
The possibility exists that the sinusitis mentioned in your MRI DX is secondary to CH. In other words, the sinusitis is a direct result of multiple CH which cause all the sinus on the CH side to gush with mucus. On the other hand, it could also be just a coincidence with no real correlation.
The possible involvement of the RCA (right superior cerebellar artery) with the trigeminal ganglia resulting in neurovascular conflict, mentioned in your MRI DX, is frequently associated with trigeminal neuralgia. This is where the RCA is physically wrapped around the trigeminal ganglia putting pressure on it and a creating a chaffing action that sensitizes the trigeminal ganglia stimulating pain very similar to CH.
I'm a 75-year-old retired Navy fighter pilot so clearly not a doctor or qualified to read MRI imagery. That said, I read studies of CH voraciously. While there are clear cases of CH being secondary to lesions in and around the trigeminovascular complex, the majority of CH are primary.
The human body is totally amazing in its capacity to heal itself if given the right nutrients. After all, it's been doing this for thousands of years before modern medicine or we wouldn't be here. I recall our family doctor telling me to remember the alphabet when it comes to vitamins (A, B, C, D, E).
Take care and please keep us posted.
V/R, Batch
