Dural metastasis masquerading as an en plaque meningioma

Abstract

Metastatic adenocarcinoma mimicking meningioma is rare; and any metastatic lesion masquerading as an en plaque meningioma is extremely rare. We report the case of a 50-year-old female, who presented with headache and left hemiparesis for 1 month and on imaging showed a dural-based enhancing mass along the right hemisphere. The patient was operated with a working diagnosis of en plaque meningioma. Histopathology revealed metastatic adenocarcinoma. This report highlights an unusual radiological presentation of a metastatic lesion as dural based en plaque variety. Metastasis should be borne in mind for any en plaque lesion with rapid clinical progression.
