Behçet's disease patients with multiple sclerosis-like features: discriminative value of Barkhof criteria.
OBJECTIVE
Behçet's disease (BD) is a systemic auto-inflammatory disorder of unknown cause, which may affect the central nervous system in around 5% of the patients [neuro-BD (NBD)], usually causing large lesions encompassing brainstem, diencephalon and basal ganglia regions. Occasionally NBD patients present with white matter lesions necessitating differential diagnosis from multiple sclerosis (MS). In this study, the efficacy of Barkhof criteria was tested in diagnostic differentiation of NBD and MS.


METHODS
Charts and MRIs of 84 NBD patients were retrospectively evaluated. Clinical and radiological features of NBD patients fulfilling (Barkhof+) and not fulfilling Barkhof criteria (Barkhof-) were compared.


RESULTS
While the Barkhof- patients (n=73) mostly displayed typical large lesions covering brainstem, diencephalon and basal ganglia regions and neurological findings consistent with brainstem involvement, all Barkhof+ (n=11) patients demonstrated MS-like white matter lesions, fulfilled McDonald's criteria and showed reduced frequency of brainstem symptoms and increased frequency of hemiparesis, hemihypesthesia and spinal cord symptoms. Moreover, the Barkhof+ group had more female patients, increased number of attacks, higher rate of oligoclonal band positivity and less patients with cerebrospinal fluid pleocytosis.


CONCLUSIONS
A subgroup of BD patients with neurological complaints displays MS-like lesions, fulfills the clinical and radiological criteria of MS and presents with clinical and laboratory features resembling those of MS rather than NBD. These results suggest that Barkhof+ patients are either an overlapping group between NBD and MS, or they represent MS patients with concomitant systemic findings of BD, rather than NBD. Barkhof criteria appear to be effective in discriminating these patients.
