“…Hida et al [17] stressed the usefulness of gadolinium-enhanced MRIs in making an accurate diagnosis preoperatively by showing a beak-like mass with ring enhancement at the level of the intervertebral space, which pointed to the abrupt loss of continuity of the PLL. Holtas et al [18] reported that T2-weighted images showed an increased signal intensity area surrounding the herniated disc, which pointed a sharp beak-like appearance. They interpreted the ring enhancement to be a result of granulated tissue infiltrating the disc fragment over a long period.…”

Intradural disc herniation at L5 level mimicking an intradural spinal tumor

et al. 2011

Intradural lumbar disc herniation is a rare complication of disc disease. The reason for the tearing of the dura matter by a herniated disc is not clearly known. Intradural disc herniations usually occur at the disc levels and are often seen at L4-L5 level but have also been reported at other intervertebral disc levels. However, intradural disc herniation at mid-vertebral levels is rare in the literature and mimics an intradural extramedullary spinal tumor lesion in radiological evaluation. Although magnetic resonance imaging (MRI) with gadolinium is useful in the diagnosis of this condition, preoperative correct diagnosis is usually difficult and the definitive diagnosis must be made during surgery. We describe here a 50-year-old female patient who presented with pain in the lower back for 6 months and a sudden exacerbation of the pain that spread to the left leg as well as numbness in both legs for 2 weeks. MRI demonstrated an intradural mass at the level of L5. Laminectomy was performed, and subsequently durotomy was also performed. An intradural disc fragment was found and completely removed. The patient recovered fully in 3 months. Intradural lumbar disc herniation must be considered in the differential diagnosis of mass lesions in the spinal canal.

“…The most common intradural masses causing a complete block are neuromas and meningiomas, and thus these lesions are frequently misdiagnosed as neoplasms. 9 Although post-myelogram CT can provide useful information, they are not able to reliably diagnose IDH. 2,4 MRI, however, can provide several clues that suggest lumbar IDH.…”

Context: Lumbar intradural disk herniation (IDH) is a rare but serious complication of spinal disk protrusions. Although the pathogenesis of lumbar IDH is still vague, it is believed to be associated with the adhesion of the posterior longitudinal ligament with the ventral wall of the dura. Diagnosis is still difficult despite current neuroradiologic imaging techniques. Findings: Two women, ages 63 and 69 years, presented with recent exacerbation of back pain. In each case, imaging studies revealed a ventral herniated disk at L1-L2. Both patients underwent surgery and in both cases a hard mass was palpated through the dura. Both patients experienced immediate postoperative relief of back pain following surgery. One patient required fusion and postoperative rehabilitation; her neurologic deficit returned to baseline. Conclusion/clinical relevance: Prompt surgical intervention is indicated for IDH; disk removal allows for symptomatic relief and minimization of neurologic deficit.

“…Jenkins 14 reported good MRI visualization of the intradural fragment as a hyperintense mass which continued from the intervertebral space to the spinal canal in a case of recurrent lumbar disc herniation. Holtas 15 reported that coronal images were useful to detect the widening of the subarachnoid space, and that T2-weighted images showed an increased signal intensity area indicating the presence of adhesions and inflammatory reaction. Hida et al 4 in their case revealed the usefulness of Gd-DTPA enhanced MRI, which showed a beak-like mass with ring-like enhancement except at the ventral surface at the level of intervertebral space.…”

Intraradicular lumbar disc herniation: report of two cases

et al. 2005

Methods: Two cases with intraradicular disc herniation at L2-3 level in one, and at L5-S1 level in the other were presented. Both patients were admitted with complaints of severe leg pain and motor weakness. In both cases, intradicular disc herniation was diagnosed during surgery. Results:The patients had uneventful recovery. They had no complaints or neurological deficits 6 and 3 months after surgery, respectively. Conclusions: The possibility of an intradural disc herniation should be kept in mind for the success of the management of lumbar disc herniation. In some patients who did not benefit from surgery, intraradicular or intradural disc herniations may be the cause of failure.
