### Patient: Doctor, I have been experiencing some unusual symptoms lately. My muscles seem to be swelling, and I have also lost some sensation in certain areas. Recently, I have also noticed that my vision has diminished and I have been having nosebleeds without any reason. What could be the cause of all these symptoms? 
### Doctor: Based on your symptoms, it's possible that you have a pituitary adenoma. This is a tumor on the pituitary gland in the brain which can cause a variety of symptoms, including muscle swelling, loss of sensation, diminished vision, and nosebleeds. We will need to run some tests to confirm the diagnosis and determine the best course of treatment.
