Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Clockwise, axial and sagittal T1 post contrast, then sagittal and axial T2 MRI of the pelvis with a large (11 cm) uterine fibroid with central necrosis, compressing the urinary bladder and rectum. Uterine fibroids are common benign tumors of the uterus that first appear during fertile years and grow with hormonal stimulation until menopause. They can be tiny and go unnoticed or grow as large as a full-term baby. In addition to expanding the waistline, fibroids can cause prolonged, heavy menstrual bleeding and pain, pelvic pain, and pressure on the bladder and rectum leading to difficulty with passing bowel movements and frequent urination. They can impair venous blood flow out of the legs, causing leg pain and heaviness. Most fibroids can be treated with a non-invasive procedure where the blood supply is cut off through a catheter threaded from the femoral artery into the uterine artery, termed uterine artery embolization or uterine fibroid embolization, performed by an interventional radiologist.

The inner layer of the eye, or retina, is similar to film in a camera. It receives light from an image we are looking at, and converts that light into electrical impulses which are sent through the fibers of the optic nerve to the brain.
