Abstract
Background
Concurrent multiple tumors developing in the spinal cord are rare, except for in genetic disorders, such as neurofibromatosis and von Hippel–Lindau disease. The presence of multiple histologically different spinal tumors in the absence of NF-2 is extremely rare. Schwannoma and meningioma can be explained partly by their common origin from the same mesenchymal cell, there is currently no explanation for the simultaneous existence of different spinal tumors other than simple coincidence.
Case presentation
After review of literature, there are thirteen such cases reported in the literature in addition to the present case. The current patient presents with lower limb weakness, and the patient radiology revealed intradural mass opposite the fourth lumbar vertebra with contrast enhancement and intradural extramedullary mass opposite the tenth dorsal vertebra with contrast enhancement in MRI spine. The coexistence of these tumors may be coincidental or might be due to a common histological origin of the Schwann cells and the meningocytes.
Conclusion
Schwannoma and meningioma have different radiological characteristics and require different managing procedures such as dural base coagulation in meningiomas and rootlet sacrifice in schwannomas.
