Ididiopatic spinal epidural lipomatosis – a rare case for lumbar spinal stenosis
G. Georgieva-Kozarova, L. Penev
Spinal epidural lipomatosis (SEL) is defined as a rare disease, characterized by, abnormal, excessive deposition of extradural mature adipose tissue, which increases and causing dural impingement and compression of surrounding neural structures in the spinal canal. Most commonly SEL is involving lumbar and thoracic spine. The incidence of the disease is unknown and diagnosis is based primarily on datafrom the MR examinations. Most often it is associated with long-term exogenous steroid therapy or endocrinopathies (Cushing syndrome or hypothyroidism). Only few cases of healthy, nonobese individuals with symptomatic epidurallipomatosis have been reported in the literature. We present a patient who belongs to this particular group, with a discogenic pain syndrome; progressive legs weakness; numbness, followed by rapid worsening of symptoms, and onset of neurogenic intermittent claudication; no history of steroid therapy, which belongs to the group of idiopathic SEL. By this time thepatient was treated conservatively for degenerative changes of the spine. Because prominent neurological deficit, magnetic resonance imaging of the lumbar spine is conducted again (the first MR examination was performed at another facility), and the patient was diagnosed as SEL. Radiological features of idiopathic SEL is discussed, along with literature review
