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.

Meningocele

Protrusion of the meninges through a defect of the vertebral column.

Its etiology remains elusive but has been associated with various conditions, such as hydrocephalus, trauma, Dyke-Davidoff syndrome, meningocele, arachnoidal cyst, meningioma, neurofibromatosis 2, and neurolemmoma.

A meningioma of the scalp that might have developed from a rudimentary meningocele.
Brantsch KD, Metzler G, Maennlin S, Breuninger H.
Clin Exp Dermatol. 2009;34(8):e792-4.
The histological examination discovered a small group of meningioma cells in the periosteum, supporting the assumption that primary cutaneous meningiomas may develop from rudimentary meningoceles.

Battistella M, Verola O, Moulonguet I, Janin A.
Ann Pathol. 2009;29(2):130-3.
There are two admitted theories for pathogenesis of heterotopic meningeal nodules: (1) tumoral proliferation of ectopic arachnoidal cells (true cutaneous meningioma), (2) meningocele-type developmental defect (rudimentary meningocele).

Identical meningothelial proliferations are well known in the skin and adjacent soft tissues of the scalp, where they have variously been called sequestrated meningoceles, meningeal hamartoma, cutaneous meningiomas, rudimentary meningocele, hamartoma of the scalp with ectopic meningothelial elements, or cutaneous heterotopic meningeal nodules.

The presence of a fibrous stalk linking the tumor to the dura mater might have been the pathogenetic connection between the meningocele and cutaneous meningioma.
