title: An unusual case of spinal cord compression from concomitant spinal epidural lipomatosis and Hodgkin's lymphoma.
abstract: Spinal epidural lipomatosis (SEL) results from an abnormal accumulation of unencapsulated fat within the epidural space and is a rare cause of spinal cord compression, which needs to be considered with a high index of suspicion. It most commonly occurs secondary to chronic corticosteroid use and endocrinopathies. Idiopathic cases are highly associated with obesity. We report an unusual case of idiopathic thoracic SEL in a 69-year-old male, with an adjacent infiltrative Hodgkin's lymphoma and associated vertebral crush fracture, which resulted in ataxia and sensory loss. Magnetic resonance imaging scans displayed extensive SEL and an infiltrative disease process causing thoracic cord compression. Surgical decompression confirmed the presence of extensive epidural lipomatosis and Hodgkin's lymphoma and subsequently led to improvement in neurological symptoms. To our knowledge, this is the first reported case of concomitant SEL with an adjacent Hodgkin's lymphoma resulting in cord compression.
