Unusual Appearance of an En Plaque Meningioma of the Cervical Spinal Canal

Abstract

Although previously not described, the diagnosis of calcified dural meningioma en plaque should be considered in all patients presenting with spinal cord and/or nerve root compression,even at cervical levels. Although ossification of the posterior longitudinal ligament and ossification of the ligamentum flavum are more common etiologies of partially circumferential spinal calcification, dural-based meningiomas with extension into the surrounding ligaments demand early recognition because they can be associated with a poorer prognosis.

Intradural Extramedullary Spinal Inflammatory Myofibroblastic Tumor: Case Report and Literature Review

“…Our first diagnosis was that of an epidural tumor based on MRI foraminal enhancement interpreted as lateral extension of the tumor, together with clinical features of an inflammatory tumor, and the fact that en plaque meningiomas of the spine are very rare [21][22][23][24], often occur in middle-aged female patients and are more likely to cause spinal cord compression than radicular symptoms [21]. The pitfall in our management was that as no tumor was found in the epidural space, intradural exploration should have followed.…”

Intraduralni ekstramedularni spinalni meningeom nivoa Th3–Th4 kod 83 godine stare pacijentkinje

“…Javljaju se kod osoba između 40 do 82 godine i kod osoba ženskog pola u odnosu 9 : 1 prema osobama muškog pola [12]. Spinalni meningeomi rastu kao "okovratnik" oko kičmene moždine infiltrirajući piju mater [13]. Češće javljanje spinalnih meningeoma kod žena se može objasniti uticajem hormonalnih faktora, jer su progesteronski i estrogenski receptori nađeni u meningeomima histološkim ispitivanjima.…”

“…Najčešći simptom je radikularni bol i bol u leđima. Rastom tumora i pritiskom na medulu spinalis javlja se mijelopatija sa vaskularnim poremećajima, praćena senzomotornim deficitom, hiperefleksijom dubokih tetivnih refleksa, posebno patelarnih, pozitivnim znakom Babinskog, poremećajima sfinktera i ataksič-nim hodom [2][3][4][5][6]10,12,13].…”

Coexistence of cervico-thoracic extradural en-plaque meningioma with multiple intracranial meningiomas

“…Meningioma usually occurs as the round type, whereas the en-plaque type grows in a sheet-like form along the dura mater. Extradural and en-plaque meningioma type is so rare such that, to the best of our knowledge, twelve cases of pure extradural en-plaque meningioma have been reported [9][10][11][12][13][14][15][16][17] (Table 1). In our article, we present pure extradural enplaque meningioma located in cervico-thoracic region with meningiomas in cranial cavity of an adult female patient.…”
