Neurological and Vascular Behçet's Disease in a Young Male without Classic Triad of Behçet's Disease: A Case Report and Literature Review.

INTRODUCTION

Neuro-Behçet's disease (NBD) is an uncommon presentation in Behçet's disease (BD) with severe course and worse prognosis. Both vascular and NBD presentation without the classical triad of BD in a single patient is rarely reported.

CASE PRESENTATION: Here a 48-year-old male had an extensive aortic aneurysm eroding vertebra for which he was diagnosed as vascular BD. Two years later, he was presented with a severe headache and cerebrovascular accident, his brain imaging showed hyperintensity in the right thalamus, basal ganglia, temporal lobe, and internal capsule, suggesting the 'cascade sign' of NBD. Surprisingly, he never had oral or genital ulcers or skin and eye involvement. He had a good response to infliximab.

CONCLUSION

Clustering of BD phenotype is an emerging area of interest. It is hypothesised that severe phenotype of vascular and parenchymal NBD can happen in the same patient owing to similar underlying pathology. This case is unique due to its severe phenotype with no features of the typical triad of BD.
