Idiopathic dural optic nerve sheath calcification with intracranial parenchymal calcification

Abstract

Introduction

We describe a unique case of dural optic nerve sheath calcification with areas of parenchymal intracranial calcification.

Case history

A 74 years old Afro-Caribbean male presented with the history of puffiness under the lids associated with left ptosis. He has right eye Amblyopia. Fundus examination revealed slightly pale and more cupped left disc compared to the right optic disc. CT scan with contrast of the orbit and brain revealed dural optic sheath calcification with areas of relatively symmetrical parenchymal intracranial calcification and with normal serum investigations.

Discussion

None of the previous reported cases had brain parenchymal calcification. Our case is unique that he not only had dural optic nerve sheath calcification but also had intracranial brain parenchymal calcification.
