Intraspinal mature teratomas rarely occur in adults. The present study describes an unusual case of adult intradural mature teratoma, which was completely resected. A 22-year-old female presented with an intermittent pinching pain in the lower right shank that had lasted for three months. Magnetic resonance imaging (MRI) results indicated a multicystic mass extending from the T12 to L2 vertebra...

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 ...

Intradural extramedullary spinal ependymomas are extremely rare. Herein, we describe a lesion-type spinal ependymoma that followed a malignant course, and discuss its clinical presentation, etiopathogenesis, and treatment. We present a patient who was diagnosed with an intradural extramedullary spinal tumor at T4-T6. The patient underwent gross total resection of the tumor without damage to the...

introduction: the aim of this study was to report surgical strategies and clinical outcomes for thoraco-lumbar intradural lipomas. intraspinal lipomas are rare congenital histologically benign neoplasms, which account for less than 1% of all spinal cord tumors. these tumors are most frequently found in the lumbosacral area as components of a dysraphic state, however, intramedullary lipomas are ...

Key highlights: Tabular columns organized by anatomical abnormality include imaging findings and a summary of key clinical data that correlates to the images Congenital/developmental abnormalities, spinal deformities, and acquired pathologies in both children and adults Lesions organized by region including dural, intradural extramedullary, extra-dural, and sacrum More than 600 figures illustra...

We report a case of a spinal intradural capillary hemangioma. On MR images, a well-circumscribed intradural mass was detected at the T8-T9 level. The signal intensity of the mass relative to the spinal cord was isointense on T1-weighted images, hyperintense on T2-weighted images, and showed homogeneous, strong enhancement on contrast-enhanced T1-weighted images. The mass had both extramedullary...

Primary spinal cord tumors constitute 2% to 4% of all central nervous system neoplasms and are characterized based on their location as intramedullary, intradural extramedullary, and extradural. A contemporary literature review of primary intradural spinal cord tumors was performed. Among intramedullary tumors, ependymomas are more common and often can be surgically resected. However, astrocyto...

Background Chordomas must be considered among the differential diagnoses for extradural spinal tumors, especially involving the clival or sacrococcygeal regions. They are often locally invasive and destructive to the osseous structures from which they arise, but rarely extend intradurally. Here, we report a unique chordoma that was intradural and spanned nearly four subaxial cervical vertebral ...

The congenital malformation known as an intraspinal bronchiogenic cyst is a rare form of endodermal (neurenteric, enterogenous) cyst lined with respiratory tract epithelium. We describe 3 new cases of intradural extramedullary bronchiogenic cyst in the Department of Neurosurgery between the years 2006 and 2014. Three patients were performed resection of intradural extramedullary bronchiogenic c...
