Lumbar spinal epidural lesions could belong to a wide spectrum of pathologies. However, some cases present with rare conditions that can cause significant neurological deficit and raise serious diagnostic challenges.

In the presence of an epidural mass with clear clinical symptomatology, rare entities like chronic epidural hematoma or posterior migrated disk material should be always considered as a differential diagnosis in patients with suspicion of extradural chronic compressions. In these cases, only the intraoperatory and histopathological exams can provide a clear diagnosis ¹⁾.
