A Case of Fabry Disease Presenting with Young Stroke and Fever

Although it is known that Fabry disease should be included in the differential diagnosis of young stroke and fever of unknown origin, it has not been reported in the literature of stroke with fever as the presentation of Fabry disease. This is relevant because stroke with fever may misguide the differential diagnosis. Here we present a young stroke patient with fever. DWI of brain MRI revealed acute multiple infarctions. Due to the fever, infectious and inflammatory origins such as infective endocarditis and autoimmune diseases were examined first. However, we could not identify the source of fever after fever workup. The fever did not respond to one week of acetaminophen and antibiotics, but responded promptly to steroid. Our patient is also a case of de novo mutation rather than being inherited that further complicates the diagnosis of this patient. Because of the rare combined presentation of stroke with fever, Fabry disease should also be considered in stroke with fever, even without family history of Fabry disease.
