Back in Nov. 2007 I had an MRI due to a history of migraines and chronic headaches - it showed nothing but a few incidental findings. Starting in March went through an entire series of events, including dentists, my GP, and an endontist, only to reach a suspected diagnosis of TN. An MRI was ordered in late May to see if I had vascular compression. It didn't show it, but did show 3mm pituitary microadenoma. I know this is VERY small. But is it possible - even remotely, that this could be the culprit, given the timeline. Given it wasn't there in Nov., the symptoms started in March, and there it was in May? My TN symptoms came on very fast, have progressed and worsened very fast, and will not let up. Also, even though my prolactin levels are within range, I have other "symptoms" for this seemingly small tumor.
In general, trigeminal neuralgia is a clinical diagnosis. Patients usually report electric like shocks across one side of the face in part or all of the face. They're usually set off by brushing your teeth, cold drinks, breeze across the face, talking, or even making facial expressions. If your symptoms are consistent with trigeminal neuralgia, it is usually uncommon for pituitary adenomas to cause these symptoms. There are reports however that some pituitary adenomas can cause generalized or pressure headaches.
