Background: Spinal navigation offers significant benefits in the surgical treatment of small thoracic intradural tumors. It enables precise tumor localization without subjecting patient to high radiation doses. In addition, it allows for a smaller skin incision, reduced muscle stripping, and limited bone removal, thereby minimizing risk iatrogenic instability, blood loss, postoperative pain, en...

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...

INTRODUCTION Giant intradural extramedullary schwannomas of the thoracic spine are not common. Schwannomas, that is, tumors derived from neoplastic Schwann cells, and neurofibromas represent the most common intradural extramedullary spinal lesions. We report the case of a patient with a giant thoracic schwannoma presenting unusually with acute abdominal pain and with delayed neurological impair...

Study Design Case report. Objective Malignant mesothelioma (MM) is an uncommon tumor of the pleural epithelium with a predilection for local spread into adjacent tissues. The sarcomatoid type accounts for ∼10% of MM cases and is associated with poorer survival than the epithelioid, desmoplastic, and biphasic types. MM commonly presents with involvement of the vertebral body or epidural space. H...

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...

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...
