“…The usual image is of a voluminous disc herniation occupying most part of the vertebral canal, with hyposignal both in T1 and T2. Two following characteristics may be associated to IDH: the loss of continuity of the PLL shown in sagittal acquisitions and the ''hawk-beak'' sign in axial T2 acquisitions, which show a triangular aspect of the herniated disc compressed laterally by the cartilaginous edges of the annulus fibrosus [15,16]. After contrast injection there may be a ring enhancement of the herniated portion of the disc by the gadolinium.…”

Introduction Intradural lumbar disc herniations are uncommon presentations of a relatively frequent pathology, representing less than 1% of all lumbar disc hernias. They show specific features concerning their clinical diagnosis, with a higher incidence of cauda equina syndrome, and their surgical treatment requires a transdural approach. Methods In this article, we describe five cases of this pathology and review the literature as well as some considerations about the difficulties in the preoperative diagnostic issues and the surgical technique. Conclusion We concluded that for intradural disc herniations the diagnosis is mainly intraoperative, and the surgical technique has some special aspects.

“…Dural erosion has been associated with disc herniation; 16,17 a proposed mechanism suggests that chronic adhesions, secondary to chronic inflammation, may lead to rupture of the dura. 17 A similar mechanism may be at play in this case, given that systemic sclerosis is a chronic inflammatory disease. The authors emphasize caution during removal of the calcinosis, as durotomies can be a significant complication.…”

“…Only a few and inconsistent MR imaging findings are useful in the preoperative diagnosis of disc herniation. 5,6,8,10) The differential diagnosis includes not only neoplastic lesions (e.g. breast or prostate cancer metastasis) but also some other benign epidural lesions such as synovial cysts, hematomas, and abscesses.…”

A 56-year-old man presented with a rare case of a voluminous herniated disc fragment mimicking an intraspinal extradural tumor on magnetic resonance (MR) imaging. He had experienced low back pain and sciatica in his right leg for 12 months, which exacerbated suddenly 4 days before admission accompanied by right quadriceps muscle weakness. MR imaging with gadolinium demonstrated a tumor-like longitudinal lesion, extending from the L1-2 to the L3-4 intervertebral disc spaces and occupying most of the right half of the vertebral canal. L2 and L3 laminectomy, as well as L2-3 right foraminotomy, were performed. We were prepared for an oncological operation, but instead, a huge disc fragment was removed en bloc from the right epidural space. The patient's postoperative course was uneventful and he demonstrated full neurological recovery within 2 months. Sequestrated lumbar disc fragments must be considered in the differential diagnosis of longitudinal extradural mass lesions in the spinal canal independently of their size. MR imaging with contrast medium can differentiate herniated disc from tumors and other epidural lesions. Nevertheless, nontypical sequestrated disc herniations are extremely rare and can be misinterpreted.
