BACKGROUND Lumbar intervertebral disc herniation and spinal tumor are major pathologies that may cause back pain and radiculopathy. Neurological symptoms resulting from disc herniation and intradural spinal tumor together, however, are very rare. CASE PRESENTATION We report a case of lumbar disc herniation which coexists with intradural schwannoma at the same spinal level in a 67-year-old man...

Here we report a case of late-onset non-dysraphic intradural spinal cord lipoma and provide a brief review of the literature. A 67-year-old man was referred to our department with a 6-month history of progressive gait ataxia. He had spastic paraparesis with left iliopsoas muscle weakness and hypoesthesia predominantly in the left leg. Magnetic resonance imaging (MRI) revealed an intradural extr...

BACKGROUND AND PURPOSE When evaluating intradural tumor dissemination in the spine, contrast-enhanced T1-weighted 2D spin-echo (2D-SE) images are frequently problematic because most of the lesions are very small. Our purpose was to compare 2D-SE images with 3D gradient-echo (3D-GE) postcontrast images to determine which technique is better for depicting intradural tumor dissemination. METHODS...

Intradural metastatic tumors of the foramen magnum region are extremely rare tumors. We report a 73-year-old patient that presented with right hemiparesis and a recent history of prostate biopsy for an enlarged prostate. Imaging revealed an anterolateral intradural foramen magnum mass with compression of the medulla. A right far lateral approach with condyle preservation was used to resect the ...

Teratoma is a type of multipotential cell tumor, which includes a mixture of two or three germinal layers of ectodermis, endodermis, and mesodermis. Although neonatal sacrococcygeal teratoma has been frequently reported, its occurrence in older age is not common. In this study, we report a rare case of spinal intradural mature cystic teratoma in a 16-year-old male, emphasizing on considering th...

Background: Schwannomas are the most common extramedullary spinal tumors. The acute hemorrhagic onset of a spinal schwannoma is a rare occurrence. Case report: We report the case of a 32-year-old woman who presents with acute onset of quadriparesis due to a hemorrhagic intradural schwannoma. The tumor arose from left C1-C2 roots and extended downward from C1 to C5 vertebral levels. An emergency...

Spinal schwannomas are one of the most common intradural extramedullary spinal tumors. However, a string of bead-like intradural extramedullary schwannoma is highly uncommon. In the paper we present a case of a long-segment string of bead-like intradural extramedullary schwannoma of cauda equina from L2 to S2.The patient had been suffering progressive low back pain and sciatica with progressive...

Ewing’s Sarcoma (ES) is a rare malignant tumor that commonly arises from skeletal bone but rarely has an extraskeletal origin. Intradural ES is rare in childhood and adulthood. Intradural metastasis is very rarely encountered in clinical observations. There are only two reports of intradural ES skip metastasis in the literature to date. Here we present the case of a 39-year-old female who was a...
