Stroke; a journal of cerebral circulation
-
Primary oxalosis is a rare disorder of oxalate metabolism, characterized by nephrocalcinosis, nephrolithiasis, and extrarenal deposition of calcium oxalate in several tissues, including the heart. We report the case of a 34-year-old man with sudden right hemiparesis and aphasia from the occlusion of the left middle cerebral artery. ⋯ The absence of other causes of stroke strengthened a cause-and-effect relation between cardiac oxalosis and cerebral infarction. Consequently, cardiac oxalosis should be considered among possible occult cardiac sources of cerebral embolism.
