A Case of Intradural Disc Herniation Mimicking a Schwannoma

TLDR
A case in which IDH was difficult to differentiate from a schwannoma on the basis of intraoperative findings and analysis of postoperative pathological results took a long time, it seems necessary to consider only performing decompression achieved by reduction surgery such as internal decompression, without cutting off the cauda equina when complete removal of lesion is difficult to achieve due to adhesion.

Intradural lumbar disc herniation: illustrative case

TLDR
The etiology, presentation, diagnostic evaluation, and treatment of ILDH are explored along with a case report and microsurgery video and a ventral dural defect was found and repaired during the procedure.

Case series of intradural disc in recurrence of lumbar disc prolapse

TLDR
Two cases presenting to the unit in the form of recurrent intradural disc disease following previous lumbar surgery occurring within 3 months of the index procedure are reported.

Intradural Lumbar Disc Herniation: A Case Report and Literature Review

TLDR
Intradural lumbar disc herniation should be highly suspected when intraoperative findings are incompatible with findings from the preoperative imaging examination, and it could be further confirmed via intraoperative ultrasonography and pathological examination of the resected tissue from the dural space.

Thoracic Intradural Disc Herniation: Key Considerations in Operative Management

TLDR
Clinical findings may not correlate with MRI findings in these rare cases due to the intradural nature of the disc material, so cases should be undertaken jointly with neurosurgical colleagues in case durotomy is needed.

Preoperative radiographic clues for transdural disc herniation: could it be predictable?

TLDR
A retrospective case analysis to analyze the imaging findings of seven cases and construct a preoperative prediction model for TDH and it is safe to consider the possibility of TDH in patients with more than two findings in the preoperative images.

Intradural lumbar disc herniations: the role of MRI in preoperative diagnosis and review of the literature

TLDR
It is believed that radiologic diagnosis of intradural herniation is possible in carefully selected patients, thanks to MRI with gadolinium, as well as the causes of this pathology, from clinical, diagnostic, and therapeutic perspectives.

TLDR
Intradural disc herniations must be considered in the differential diagnosis of prolapsed intervertebral disc disease especially with recent worsening of symptoms and mismatch of unenhanced MRI findings with intraoperative findings.

Abstract 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

Intradural Disc Herniation and Epidural Gas: Something More Than a Casual Association?

TLDR
The potential presence of an intradural disc herniation must always be considered when performing an open discectomy on a patient whose CT scan study shows the presence of epidural gas, given the relative rarity ofintradural herniations and intraspinal gas.

Intradural Lumbar Disc Herniation: Report of Three Cases with a Review of the Literature

TLDR
Intradural lumbar disc herniation (ILDH) is rare, and it is seldom suspected preoperatively, but the neurologic prognosis appears to be closely linked with preoperative duration of neurologic symptoms.
