I've received an MRI report stating that I likely have an arachnoid cyst on my brain (specifically an incidental posterior fossa arachnoid cyst measuring 1.0 x 0.8 cm)) I'm digging up info now. I at least have what the Dr. is calling sinus disease as a result of inflammation, and I don't know whether it is causing all my other symptoms. My other symptoms are over the past year include markedly increased fatigue, frequent illness, lower back pain, and sexual problems (decreased libido, low LH, FSH, testosterone levels, reduced potency), which was diagnosed originally as secondary pituitary hypogondism. My ? is to what extent is it possible this arachnoid cyst is causing these symptoms I've had over the past year?
All of your symptoms are signs of pituitary disfunction. Are you getting replacement hormone treatment, especially hydrocortisone, to support adrenal cortisol? Very important.
I wouldn't know if the arachnoid cyst is contributing to any of your symptoms.
Sinus problems can be caused by loss of adrenal cortisol. My son has this problem.
Thanks enzymelover and rumpled. Yes, that was the original reason for schduling the MRI - to examine the pituitary gland. Dr. thought I likely had symptoms of secondary pituitary hypogonadism. Pituitary looked fine on the MRI though, no pituitary tumors, so now I have to wonder whether it is this arachnoid cyst causing me these symptoms or yet something else.
Up to 40% of pituitary tumors do not show up on MRIs. Reason can be as easy as the radiologist missed it or that it fell between the slices - as MRIs do 3mm slices and pit tumors can be that small.
Sometimes surgeons can see what a radiologist missed.
Therefore, testing means more than an MRI.
If the symptoms seem pituitary, get more testing and get more and more testing.
Teeny tumors can still wreak havoc. Size does not matter with pit tumors.
