title: [A case of meningioma en plaque: review of 73 cases].
abstract: The patient was a 41-year-old female who became aware of a protuberance in the right frontoparietal vault 2 years ago. Three dimensional CT showed a hyperostosis involving the diploe of the skull, and the rough surface of the inner table. In the gadolinium--DTPA enhanced MR images, an entity with a flame-like appearance invading the swollen skull rose from thick homogenously-enhanced dura. The lesion was surgically resected in a circle, and removed with the adherent dura. Histologically, this lesion exhibited a lobular pattern of meningothelial cells, and roughly invaded into the Haversian canals of the skull through the dura. Postoperatively, there was no neurological or physical deficit. In this paper, we reviewed clinical and pathological features of 73 meningioma en plaque cases including the present case.
