Tumours
Primary Spine Tumours
Primary spinal column Tumours (originating from the spinal column) rarely occur and are either benign or malignant.
Malignant Spinal Tumours
Benign Spinal Tumours
Benign Spinal Tumours
Osteochondroma is a slow growing tumour of the cartilage usually affecting adolescents. It is uncommon and is usually found in the posterior (rear) spine.
Osteoid Osteoma is a small bone tumour (less than 2 cm). It usually affects adolescents causing night pain and may result in spinal deformity.
Osteoblastoma affects children and adolescents. These Tumours can be large, aggressive, and painful sometimes causing spinal deformity and paralysis.
Aneurysmal Bone Cysts (ABCs) typically cause pain and swelling usually affecting children and adolescents. These Tumours can be large and quite vascular.
Giant Cell tumour is known to affect children, adolescents and young adults. These Tumours can be found at the cervical, thoracic, or lumbar segments of the spine, but are more common in the sacrum.
Hemangioma occurs most often in the thoracic spine. These Tumours affect adults and are known to be progressive vascular masses that can cause vertebral collapse and paraparesis (slight paralysis).
Eosinophilic Granuloma is usually seen in the vertebral bodies of children and adolescents. When this tumour is systemic it is termed Histiocytosis X. Rarely do these Tumours lead to vertebral collapse and paraparesis. On occasion, they may heal spontaneously.
Malignant Spinal Tumours
Plasmacytoma presents in middle aged and older adults. These Tumours are common in the pedicle and vertebral body and may cause paraparesis.
Myeloma is the most common primary malignant tumour of bone. It typically affects adults greater than 40 years of age. It tends to be generalized, involving multiple bones, but back pain and involvement of the spine is the most common presenting complaint. Treatment is palliative; meaning that disease can be controlled, but not completely cured. Chemotherapy is used to control the pain and slow the progression of the disease. Surgery may be required if pathological fractures develop or there is compression of the spinal cord.
Ewing's Sarcoma is an aggressive tumour affecting adolescents and young adults. In some cases, it may metastasize.
Lymphoma may present in one or more vertebral bodies in middle aged or older adults. Sometimes the lymphatic system is involved.
Chondrosarcoma is a tumour affecting spinal cartilage in middle-aged adults. It grows slowly but can be dangerous. Usually aggressive medical intervention is required.
Osteosarcoma is bone cancer found in adolescents and middle-aged adults. These Tumours may metastasize requiring aggressive medical therapy.
Chordoma is usually seen in adults frequently (50%) involving the sacrum, although it can affect other parts of the spine such as the occipito-cervical junction (where the head joins the neck). These Tumours often require aggressive medical therapy.
Spine pain does not always indicate tumour presence. However, early medical intervention is always warranted if spine pain does not resolve or if neurologic deficit is experienced.

Secondary Spinal Tumours
Secondary spinal column tumours (originating from somewhere else in the body) are known to metastasize (spread) via arteries, veins, the lymphatic system, and directly. Malignant Tumours of the breast, prostate, lung, and kidney can spread into the spine.
This is the most COMMON cause of spinal column tumours in adults.
Spinal Tumours can be dangerous when they cause spinal canal compression, which may lead to neurologic dysfunction (e.g. paralysis).
Many patients will present with neck pain as the primary symptom. The pain can occur at rest, be worse at night, and may or may not be related to activity. Other symptoms may include sciatica, numbness, paraparesis (slight paralysis), spinal deformity (e.g. scoliosis, kyphosis), and fever.
Spinal cord tumours are a different entity and are rare also. They are tumours that affect the tissue immediately surrounding the spinal cord and nerve roots and may also originate within the cord or nerves. They are also classified into primary and secondary, benign or malignant.
