OBJECTIVES To describe a case of extramedullary-intradural metastases causing cauda equina syndrome (CES) as the primary syndrome of lung cancer, and to review the pertinent medical literature. SUMMARY OF BACKGROUND DATA Intradural spinal metastasis is rare, accounting for 6% of all spinal metastases. Of all primary lesion types, lung carcinoma is about 40-85%. Extramedullary-intradural metas...

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...

Intradural spinal metastasis is rare. This is the third case ever reported on the finding of intradural spinal metastasis from a renal cell carcinoma that had been removed surgically. The patient had a history of epidural metastasis for which excision and anterior stabilization were done 3 years before the new presentation with cauda equina lesion. Seeding from the involved osseous structure to...

hemangiomas are considered as vascular malformations which are categorized by the type of vascular channel to capillary, cavernous, venous or arteriovenous(1). their usual locations are soft tissue , cutaneous or subcutaneous tissue and bone especially vertebra(2).however, intradural extramedullary hemangiomas are rare and most of them fall in cavernous type category. hereby, authors report a w...

Patients with spinal abnormalities infrequently present with intradural intramedullary bleeding. The more common causes include spinal trauma, arteriovenous malformations and saccular aneurysms of spinal arteries. On occasion, spinal cord tumors either primary or metastatic may cause intramedullary bleed with ependymoma of the conus medullaris. Spinal nerve sheath tumors such as schwannomas onl...

Intradural spinal cord abscesses especially in the cervical spine are a rare occurrence. We report a rare presentation of an intradural extramedullary abscess at the atlantoaxial level, initially misdiagnosed as an epidural collection. The patient presented with worsening quadriparesis preceded by a 2-week history of upper respiratory tract infection and neck pain. Magnetic resonance imaging sh...

El bloqueo espinal alto es una de las complicaciones más graves que pueden suceder durante la anestesia neuroaxial cesárea. Una sus causas el rescate epidural fallida mediante intradural. Puede derivar en hemodinámicas y respiratorias por lo primordial reconocimiento tratamiento precoz para mejorar pronóstico. Para evitar un al utilizar intradural tras administrar bolo epidural, se debe esperar...

Intradural disc herniation is found in only 0.3% of cases of disc herniation. The majority of these (>95%) are found in the lumbar region, with fewer than 5% occurring in the thoracic region [1,2]. While imaging occasionally raises suspicion of an intradural component to a herniated disc, the majority of cases are diagnosed intraoperatively [1-6]. We describe a case of an intradural thoracic di...

The authors present a unique case of an intradural extramedullary ganglioneuroma in the thoracic spine of an adult. Intraspinal ganglioneuromas are rare, benign tumors of sympathetic nervous tissue origin, but exclusively intradural ganglioneuromas have not been reported.

Intradural lumbar disc herniation is a rare complication of disease. The mechanism by which herniated tears the dura matter remains unknown. preoperative diagnosis an intradural still difficult. We report our experience dealing with case at level L3/4 in 34-year-old man. Based on current experience, we found that attachment ventral to posterior longitudinal ligament can be favorable factor indi...
