Chronic Sinusitis

Chronic sinusitis can be caused by inflammation of the membranes of the sinus cavity or blockage of the sinus passage way from draining normally. Chronic sinusitis last longer than acute sinusitis. It is also less common than acute sinusitis. It can produce less severe symptoms, but can cause damage to the sinuses.

Some symptoms of chronic sinusitis are as follows:

-drainage of a thick, yellow or greenish discharge
-difficulty breathing through nose
-headache
-sore throat
-nasal congestion
-cough
-facial pain and pressure in forehead, temples, cheeks, nose and behind the eyes

There are some different treatments for chronic sinusitis, they are antibiotics, corticosteroids, decongestants, antihistamines, moisture and humidification.

Chronic sinusitis can be diagnosed several different ways. CT is a better diagnostic test for sinuses than MRI, however, MRI can be done. Nasal and sinus cultures can be done and an allergy test can be done.

Optic Glioma

Optic glioma is one of two most common optic nerve tumors. The other common tumor is optic nerve meningioma. Optic glioma arises from the optic nerve. Optic glioma may only effect one optic nerve or both nerves. These are very uncommon and grow slowly. This type of tumor rarely turn into cancer and usually appear during childhood. Agressive glioma is most common in adults and benign optic glioma are most often in younger patients.

Symptoms are the following:
reduce vision
vision loss in one or both eyes
involuntary eye movement
one or both eyes may bulge out

MRI is better to demonstrate optic glioma but CT can also be used.

Treatment are the following:
Surgery
Radiation therapy
Chemotherapy

Pituitary Microadenoma

Pituitary Microadenoma

This type of pituitary tumor is a non-cancerous or benign growth. These tumors are smaller than 10 mm in size. Most pituitary tumors are usually microadenomas.

There are several types of Pituitary Microadenomas. They are broken down into two different categories, depending on if they produce hormones or not.
1. Functioning pituitary microadenoma
2. Nonfunctioning pituitary microadenoma

Functioning microadenomas produce one or more of the pituitary hormones. There are different types of Functioning Pituitary micradenomas and each type caused different symptoms.
ACTH producing
Thyroid hormone producing
Growth hormone producing
Prolactin producing

Nonfunctioning pituitary microadenomas do not produce hormones.

Symptoms range from anywhere to being tired, headaches, dizziness and vomiting. These will vary depending on the size of the microadenoma and the location.

MRI and CT scans are both good test, along with others to help diagnose pituitary microadenomas.

Treatment also varies on the type of microadenoma, hormone activity, how big it is and the location of it. Some treatment can include therapy, surgery and radiation therapy.

I have never seen this type of pathology while working in MRI. If you want more information about microadenoma and the pictures above, visit www.ghettodriveby.com,
