Idiopathic Late Subacute Epidural Hematoma: An Uncommon Cause of Pure Lumbar Radiculopathy with MR of Spinal Epidural Lesions Differentials;Revisited

Spontaneous spinal epidural hematoma is an increasingly recognized entity in clinical practice. MR is a valuable tool in diagnosis yet its chronological signal changes and different pattern of enhancement may impose a diagnostic difficulty. Other worrisome differential diagnostics with different management, prognoses represent the daily radiologist challenge. We present a case of pure lumbar radiculopathy caused by accidentally discovered spontaneous late sub-acute epidural hematoma and discuss the diagnostic differentials of lumbar spinal epidural mass lesions.
