Summary
We describe a rare instance of paraparesis, or leg weakness, caused by thoracic spinal epidural lipomatosis. This condition occurred in a female patient without any known risk factors.
Area of Science:
- Neurology
- Neurosurgery
- Spinal Cord Diseases
Background:
- Spinal epidural lipomatosis (SEL) is characterized by excessive fat accumulation in the epidural space.
- SEL can lead to neurological deficits due to spinal cord or nerve root compression.
- While often associated with certain conditions like Cushing's syndrome or steroid use, idiopathic SEL can occur.
Observation:
- A female patient presented with paraparesis, a form of leg weakness affecting both lower limbs.
- Diagnostic imaging revealed significant thoracic spinal epidural lipomatosis.
- The patient had no identifiable predisposing factors, such as exogenous steroid use, obesity, or endocrine disorders.
Findings:
- The thoracic spinal epidural lipomatosis was the direct cause of the patient's paraparesis.
- This case highlights the potential for SEL to develop idiopathically, even in the absence of typical risk factors.
- Surgical decompression may be indicated for symptomatic SEL.
Implications:
- This case expands the understanding of spinal epidural lipomatosis etiology and presentation.
- It underscores the importance of considering idiopathic SEL in the differential diagnosis of myelopathy.
- Further research may elucidate the specific mechanisms underlying idiopathic SEL development.
