Differential Diagnosis
- Single most likely diagnosis
- Degenerative disc disease: This is the most likely diagnosis given the presence of multilevel mild degenerative disc space narrowing and facet joint degenerative changes in the lower lumbar spine. The patient's symptoms are likely related to the wear and tear of the spinal discs and facet joints.
- Other Likely diagnoses
- Lumbar strain: The patient may have experienced a lumbar strain, which could be causing their symptoms. The absence of a discrete fracture on x-ray does not rule out a strain.
- Spondylosis: This condition, characterized by a defect in the pars interarticularis, could be contributing to the patient's symptoms. However, it would typically be visible on x-ray or other imaging studies.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Cauda equina syndrome: Although unlikely, this condition is a medical emergency that requires prompt attention. It is characterized by compression of the cauda equina, which could be caused by a variety of factors, including a herniated disc or spinal stenosis.
- Spinal infection (e.g., osteomyelitis, discitis): Infections of the spine can be devastating if left untreated. While the patient's presentation does not strongly suggest an infection, it is essential to consider this possibility, especially if the patient has a fever, recent travel history, or other risk factors.
- Spinal tumor: Although rare, spinal tumors can cause symptoms similar to those experienced by the patient. It is crucial to consider this possibility, especially if the patient has a history of cancer or other risk factors.
- Rare diagnoses
- Spondylolisthesis: This condition, characterized by the slipping of one vertebra over another, could be contributing to the patient's symptoms. However, it is less likely given the absence of a discrete fracture on x-ray.
- Ankylosing spondylitis: This inflammatory condition can cause degenerative changes in the spine, but it is relatively rare and typically presents with other systemic symptoms.
