Intradural lumbar disc herniation is a rare pathological entity. The pathogenesis of intradural lumbar disc herniation is not known clearly. Intradural disc herniations usually occurred at the L4-L5 levels but have also been reported at other levels. However, intradural disc herniation at L5-S1 is quite rare. There are approximately nine reports in the English literature of intraradicular disc ...

Intradural disc herniation is rare. In a colon cancer patient who suffered from low back pain for several years, MRI examination showed evidence of vacuum phenomenon and ring enhancement at the level of L3-4. Intradural herniation of an intervertebral disc was confirmed surgically. Pathological evidence of intradiscal gas is rarely reported in the literature, however, an association between int...

Pseudotumor cerebri is a condition of increased intracranial pressure in the absence of clinical, laboratory or radiological pathology. Spinal intradural hematoma formation after lumboperitoneal shunt (LPS) implantation is very rare, but it can cause sudden and serious deterioration. In this report, we present a patient who developed an intradural hematoma following LPS operation. A 27-year-old...

The authors discuss their recent experience with anteriorly located C1-C2 neurofibromata in five patients with cervical myelopathy and magnetic resonance scans consistent with intradural extramedullary masses in this region. Surgery was performed using a posterolateral approach with microscopic intradural exploration. Gross total intradural tumor removal was achieved in all cases. Improvement i...

I spinal tumors are usually primary tumors, and schwannoma, ependymoma and meningioma are most common ones at lumbar localization. Intradural metastasis accounts for very low percent of spinal metastases (7,15). Approximately 6% of spinal metastases are intradural. Most metastases are solitary lesions in configuration. Adenocarcinoma metastases are frequently originating from lung and breast. I...

Intradural disc herniations comprise 0.26-0.30% of all herniated discs. Five percent are found in the thoracic, 3% in the cervical, and 92% in the lumbar region. Although intradural disc herniation may be suspected on preoperatively made CT scans, myelograms, and MRI scans, establishing the diagnosis prior to the surgery is difficult. We present a case of the patient with severe neurological de...

Spinal cord stimulation (SCS) is an alternative or adjunct therapy to treat chronic pain, a prevalent and clinically challenging condition. Although SCS has substantial clinical success, the therapy is still prone to failures, including lead breakage, lead migration, and poor pain relief. The goal of this study was to develop a computational model of SCS and use the model to compare activation ...

Intervertebral intradural lumbar disc herniation (ILDH) is a quite rare pathology, and isolated intradural lumbar disc herniation is even more rare. Magnetic resonance imaging (MRI) may not be able to reveal ILDHs, especially if MRI findings show an intact lumbar disc annulus and posterior longitudinal ligament. Here, we present an exceedingly rare case of an isolated IDLH that we initially mis...

UNLABELLED Intradural arachnoid cysts are rare lesions that frequently arise posterior to the spinal cord in the thoracic spine region. Those located at the cervical spine level, anterior to the spinal cord are even rarer. The usual treatment of symptomatic intradural spinal cysts involves surgical removal through a posterior approach using a laminectomy or laminotomy. However, ventrally locate...

Spinal hydatid cysts account for 1% of all cases of hydatid disease; primary intradural hydatid cysts are uncommon. We present a case of pathologically confirmed intradural spinal cyst hydatid in an otherwise healthy patient who showed no other evidence of systemic hydatid cyst disease. The patient presented with back pain, paraparesis, and weakness. An intradural extramedullary cystic lesion w...
