MRI Results--Will you help interpret?

[shasto]

All findings are normal except....

Note is made of empty sella configuration with CSF intensity fluid within mildly expanded pituitary fossa. On sagittal images there was nodular soft tissue along the floor of pituitary fossa which appeared isointense with the gray matter. Postcontrast sequence specifically obtained of the pituitary fossa did not demonstrate any enhancement. This most likely represents a midline Rathke cleft cyst. There is no infundibular stalk deviation.

Note was made of mucous retention cyst in bilateral maxillary sinuses measuring up to 2 cm on wide and 1.5 cm in maximum dimension on the left side. Bilateral internal auditory canals are symmetric with no enhancing lesions identified.

Impression:
1. No acute intracranial process, specifically no restricted diffusion to suggest an acute infarct. No intraparenchymal hemorrhage or mass effect is identified.
2. Incidental note is made of empty sella configuration with a midline posterior nonenhancing cyst measuring 5.3 x 5 mm in craniocaudal and AP dimensions. This most likely represents a midline Rathke cleft cyst.
3. Mucous retention cyst in bilateral maxillary sinuses.

What does all this mean? How serious is it? I went to the neurologist because of recurrent headaches, dizziness and pulsatile tinnitus in my left ear. I also had MRA and MRV of the brain done with and without contrast...both were normal results. I have an appointment with an ENT, my endocrinologist and neurologist in the next two weeks...

My history...30 year old female, obese, hypothyroid, endometriosis, and hypertension. Drugs: ramipril 10 mg, synthroid .05 mg, topamax 25 mg, and vicodin 500AP/5mg and flexeril 10mg (for two herinated discs)...I started the ramipril and synthroid in May of 2009 when I was first diagnosed with hypothyroidism and hypertension. Topamax was just started two weeks ago. I just underwent second epidural injection for herinated discs after initial diagnosis in May as well.

I appreciate your feedback--Thank you so much.
