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.
Differential Diagnosis
Life Threatening Causes
Life threatening diseases to exclude immediately include:[1][2][3][4][2][3][5][6][7][8][9][10][11][12][13][14][15][16][17]
- Abdominal aortic aneurysm
- Adrenal hemorrhage
- Aortic dissection
- Arachnoiditis
- Cauda equina syndrome
- Cervical fracture
- Chronic stable angina
- Epidural abscess
- Pulmonary embolism
- Retroperitoneal hematoma
- Traumatic aortic rupture
- Vertebral fractures
Common Causes
- Abnormal posturing
- Degenerative disc disease
- Depression
- Osteoarthritis
- Pregnancy
- Premenstrual syndrome
- Sciatica
- Spinal disc herniation
- Spinal stenosis
- Trauma
