Quick Answer. A hypodense mass or lesion is part of the findings of a radiology scan, such as a computerized tomography, or CT, scan, usually in area of the liver or pancreas. During a CT scan, this area will light up, but the finding of a hypodense mass does not necessarily indicate tumors or cancerous lesions.
When you boil an egg, a physical change occurs that causes it to harden. The time it takes to hard boil an egg depends on the size of the egg. Give the egg time to reach room temperature, about 12 to 15 minutes. Place the eggs in a pan of water and give the water time to boil. It should take eight to 10 minutes for the water to begin to boil, less time if you cover the pan with a lid. You can also add salt to the water to encourage the water to boil faster.
Ease the egg into the simmering water and let cook. As a general rule of the thumb, cooking time should vary between two and a half to four minutes. However, how long it takes to poach an egg this way will also rest on how well you like your eggs done. In any case, poaching an egg in boiled water will not go beyond four minutes to get a firm white but a still runny yolk.
