Leiomyosarcoma isa rare, malignant (cancerous) tumor that arises from the smooth muscle lining the walls of the uterus. While the exact cause of a uterine leiomyosarcoma is unknown, associated risk factors include long-term use of tamoxifen (five years or more), history of pelvic radiation, and inherited conditions (e.g. childhood retinoblastoma)

Lipomas are the most common type of fat-containing, benign (non-cancerous) growths and demonstrate a characteristic appearance on MRI. The cause is not fully understood, but there is a genetic factor as they typically run in families.

A lacunar stroke (infarct) is when blood flow going to the small arteries deep inside the brain become blocked. The major risk factor for getting lacunar strokes is chronic high blood pressure, which can cause the small arteries to narrow over time; other modifiable risk factors include poor cholesterol levels, diabetes and smoking.If there is a new stroke, think “FAST” - Facial drooping, Arm weakness, Speech difficulties, Time is of the essence - call 911. Treatment is focused on restoring blood flow to the brain.

The heart has 4 main chambers - 2 atria, one that receives blood from the body and another from the lungs, and 2 ventricles, one which pumps blood to the body and the other to the lungs. The left ventricle appears enlarged (hypertrophy). Causes of left ventricle enlargement include: “normal” athlete’s heart, high blood pressure, aortic valve stenosis and hypertrophic cardiomyopathy.

Thoracic endometriosis is a rare condition that happens when endometriosis patches grow on or around the lungs. This can cause shortness of breath, chest pain, cough, and in some cases, a collapsed lung.

Lymph nodes are small bean-shaped structures that are part of the body's immune system. They filter substances that travel through the lymphatic fluid, and they contain lymphocytes (white blood cells) that help the body fight infection and disease. There are hundreds of lymph nodes found throughout the body. Adenopathy (also known as lymphadenopathy) refers to lymph nodes that have become enlarged or swollen due to an infection.

Lymphoma is a cancer starting in immune system cells called lymphocytes. They can occur in the nasal cavity and are the third most common cancer found in this area.

Lymphoma is a cancer starting in immune system cells called lymphocytes. They can occur in the paranasal sinuses and are the third most common cancer found in this area.

Cirrhosis is scarring of the liver that can be caused by many forms of liver diseases and conditions, such as chronic viral infections of the liver (i.e. hepatitis B and hepatitis C), fatty liver, or chronic alcohol use disorder. It is an irreversible condition. Cirrhosis is often asymptomatic (does not cause symptoms) until liver damage is severe. Symptoms, when present, may include fatigue, easy bleeding or bruising, loss of appetite, nausea, fever, and unexpected weight loss.
