Overview

There are several life-threatening causes of back pain, including spinal cord or cauda equina compression, aortic dissection, aortic aneurysm, vertebral osteomyelitis, epidural abscess, and metastatic cancer. These should be evaluated alongside other possible causes of back pain by carefully assessing the nature of the pain, and obtaining a thorough patient history.

 ==Overview==
-There are several life-threatening causes of back pain which need to be evaluated for first, which include; spinal cord or cauda equina compression, aortic dissection, aortic aneurysm, vertebral osteomyelitis, epidural abscess, and metastatic cancer. The other possible causes of back pain can be evaluated for by carefully assessing the nature of the pain, and obtaining a thorough patient history.

+*May demonstrate an osteolytic or osteoblastic lesion
+*Elevation of the periosteum may be noted, and is known as "Codman's triangle"
+*Tumor spread to periosteum is known as "sunburst" sign
+CT
+*Chest CT is done to rule out pulmonary involvement
+*May also demonstrate the margins and extent of tumor
+MRI
+*Useful in detection of soft tissue involvement
+Bone scan
+*Increased uptake is noted in regions of metastasis
+*Technetium-99 - methylene diphosphonate is usually used
 |
+*Cardiac function should be assessed before the use of doxorubicin or daunorubicin
