Meningioma

A rare, mostly benign, primary tumor of the meninges (arachnoid cap cells), usually located in the supratentorial compartment, commonly appearing in the sixth and seventh decade of life, clinically silent in most cases or causing hyperostosis close to the tumor and resulting in focal bulging and localized pain in less than 10% of cases. Additional features may include headache, seizures, gradual personality changes (apathy and dementia), anosmia, impaired vision, exophthalmos, hearing loss, ataxia, dysmetria, hypotonia, nystagmus, and rarely spontaneous bleeding.

Schwannoma

A benign nerve sheath tumor composed of Schwann cells.

	Adrenal Cortical Adenoma in the Spinal Canal: A Case Report and Review of the Literature.
	Nemir J, tenger M, Jakovevic A, Domazet I, Njiric N, Paladino J. J Neurol Surg A Cent Eur Neurosurg. 2019;:.
	These tumors have nonspecific MRI features and therefore can be easily confused with other common spinal tumor types such as ependymoma, schwannoma, meningioma, and metastasis.

	Although distinguishing a schwannoma of the falx cerebri from a falx meningioma and metastasis is difficult preoperatively, inclusion of schwannoma of the falx cerebri in the differential diagnosis is important, especially when the patient is relatively young and/or the tumor lacks dural tail sign.

	Zhan Z, Yan X, Nie W, Ding Y, Xu W, Huang H. World Neurosurg. 2019;:.
	Except in cases of neurofibromatosis, it is very rare for tumors of different pathological types to exist concurrently at the same spinal level, with only 9 cases reported to date, in which meningioma was found with schwannoma in 7 cases and with neurofibroma in 2 cases.
