Cerebral Whipple's disease with a stroke-like presentation and cerebrovascular pathology.
Although neurological symptoms are common in Whipple's disease, patients rarely have a purely neurological presentation and involvement restricted to the central nervous system is uncommon. A 39 year old woman presented with a meningoencephalitic illness, which responded to penicillin. Eleven months later she developed recurrent stroke-like episodes. Patchy enhancing meningeal, cortical, and subcortical lesions thought to be vascular in origin developed within nine days of the onset of symptoms. No evidence was found of a cardiovascular source of emboli, vasculitis, or thrombophilic condition. A brain biopsy showed meningoencephalitic features suspicious of Whipple's disease associated with leptomeningeal arterial fibrosis and thrombosis. DNA polymerase chain reaction confirmed Tropheryma whippelii in both blood and brain tissue. The neurological manifestations of cerebral Whipple's disease are varied and very rarely include stroke-like symptoms. The pathogenesis of cerebral infarction in Whipple's disease is not well established but arterial fibrosis and endocarditis complicated by embolisation have been reported. This case emphasises the importance of early brain biopsy in unusual cases of stroke and illustrates the clinical utility of polymerase chain reaction to confirm Whipple's disease.
