By Michael Perry, M.D. Degenerative disc disease frequently causes lower back pain, otherwise known as lumbago. This condition is one of the most common and can arise due to a variety of factors, including sudden trauma, but the most common reason for developing degenerative disc disease is simply growing older.
Background: Bony raised bumps on the forehead are not rare and are known as osteomas. They occur due to the development of normal bone under the periosteum of the non-hair bearing forehead.They are benign overgrowths of bone that are non-mobile.arge frontal osteomas that are more than just a bump on the forehead are rare. But they present differently due to their size and their association with other symptoms such as pain. A CT scan will show that the osteoma is more aggressive as it extends deeper into the skull bone and is a truly expansile bone lesion.
An osteoma is a benign growth that is most commonly found in the skull when new bone grows on old bone or on tissue. When an osteoma grows on bone it is called a homoplastic osteoma and when it grows on tissue it is called a heteroplastic osteoma.The cause of osteoma is not known, but they have been linked to trauma and also to infection.Osteoma is also a symptom of Gardnerâs syndrome.hen an osteoma grows on bone it is called a homoplastic osteoma and when it grows on tissue it is called a heteroplastic osteoma.
