“…8,9,11 PIEMs were almost reported in an individual case in the previous literature because of their rarity. 4,9,10,[12][13][14][15][16][17][18][19] Bassiouni et al 10 reported that PIEMs accounted for 4.4% of all PEMs in the reviewed 91 PEMs. It can be calculated that PIEMs as a proportion of all meningiomas is between 0.04% and 0.09%.…”

“…Usually, PIEMs have 2 kinds according to the origins. 4,[8][9][10][12][13][14][15][16][17][18][19] One arises from the underlying outer layer of dural mater and develops in the epidural space, 12,13,16 the other roots in the diploe or the inner table of skull and directly extends to the epidural space through the inner table. 4,9,10,14,15,[17][18][19] Since Rao et al 16 reported the first case of PIEMs in 1971, previous reports on PIEMs had been largely limited to the individual case, reflecting their rather rarity.…”

Objective: We reviewed 17 cases of primary intracranial extradural meningiomas (PIEMs) (including our 5 cases) reported in the literature so as to develop a better understanding of their clinical characteristics, treatment, and prognosis. Materials and Methods:The clinical data of 17 cases of PIEMs, including our 5 cases, were analyzed on their demographic features, presenting symptoms and duration, imaging and surgical findings, surgical results, pathologic grades, histologic subtypes, and follow-up results.Results: PIEMs accounted for 0.04% to 0.14% of all meningiomas. The most common presenting symptom (41.2%) was a painless, gradually expanding mass in the region of the lesion. PIEMs being located in skull convexities constituted 88.2% of all cases, whereas skull bases only 11.8%. All PIEMs patients were uneventful perioperatively after complete resection of tumor except 1 who died of primary cardiac arrest during operation. A total of 88.2% of PIEMs were grade I, 11.8% grade II. Ten cases of PIEMs were given a mean 2.16-year follow-up. As a result, no recurrence and death were found.Conclusions: PIEMs have some marked clinical characteristics. Total tumor removal together with a wide excision of all involved tissues followed by the reconstruction of tissue defects is the best surgical project. The prognosis is excellent after surgical complete resection.

Parapharyngeal meningioma extending from the intracranial space

et al. 1990

A 50-year old woman with a giant parapharyngeal meningioma extending from the intracranial cavity was admitted to our hospital. The parapharyngeal tumor was biopsied using the transoral approach and a histological section diagnosis suggested meningioma. Thereafter, further examination by magnetic resonance images (MRI) and contrast enhanced CT scans revealed a diffuse meningioma en plaque in the posterior fossa. Invasion extended from the clival dura to the right sigmoid sinus. The extracranial extension of a meningioma is very rare but a few cases have been reported. In almost all of the reported cases, a large intracranial meningioma was simultaneously or previously verified by CT scans. Our case was special in that the intracranial mass was not voluminous but showed en plaque extension, and also because the pathway of the extracranial extension through the jugular foramen was clearly visualized by CT and MRI. Obliteration and invasion of the right sigmoid sinus and the internal jugular vein by tumor were also demonstrated.

Ectopic dural osteolytic meningiomas

Intracranial meningiomas usually originate from the arachnoidal cells of the internal dural layer: meningiomas that originate from different sites are ectopic. The authors describe the case of a small meningioma adhering to the external dural layer without involvement of the internal layer, accompanied by osteolysis of the internal surface of the skull. A review of the literature on cranial ectopic meningiomas yielded only four cases described as originating from the external dural layer. Osteolysis of the skull was always present and was not found to have prognostic significance. The authors suggest that these four primary ectopic meningiomas originating from the external dural layer should be differentiated from intraosseous meningiomas of the skull.
