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.

Epidermoid cyst

Nontender, round and firm, but slightly compressible, intradermal or subcutaneous cyst measuring 0.5-5 cm in diameter. Epidermal cysts are intradermal or subcutaneous tumors, grow slowly and occur on the face, neck, back and scrotum. They usually appear at or around puberty, and as a rule an affected individual has one solitary or a few cysts.

Liponeurocytoma of the Cerebellopontine Angle.
Chiaramonte C, Rabaste S, Jacquesson T, Meyronet D, Cotton F, Jouanneau E, Berhouma M.
World Neurosurg. 2018;112:18-24.
This unusual cisternal location raises the issue of the differential imaging diagnosis with much more common CPA tumors (e.g., meningiomas, vestibular schwannomas, ependymomas, epidermoid cyst, hemangioblastomas, medulloblastomas).

A cerebellopontine angle lesion could be a vestibular schwannoma, meningioma, epidermoid cyst, or less likely, arachnoid cyst, metastasis, lower cranial nerves schwannoma, lipoma, hemangioma, paraganglioma, or vertebra-basilar dolichoectasia.

In addition to these etiologies, space-occupying lesions such as meningiomas, epidermoid cysts, medulloblastomas, and arachnoid cysts are rare causes of acquired Chiari malformation and syringomyelia.

Epidermoid cysts are slow growing lesions believed to arise from inclusion of ectodermal elements during neural tube closure, while meningiomas arise from arachnoidal cells; their association has rarely been reported previously.

Imaging findings are not pathognomonic, and the differential diagnosis usually includes eosinophilic granuloma (Langerhans cell histiocytosis), osteomyelitis, metastasis, osteoblastoma, epidermoid cyst, hemangioma, fibrous dysplasia, fibrosarcoma, and meningioma.

At magnetic resonance imaging, the epidermoid cyst, unlike the majority of intra-cranial tumours, such as acoustic neuroma and meningioma, does not show gadolinium-enhancement; this again supporting the important role of magnetic resonance imaging in the differential diagnosis of intra-cranial neoformations.
