A 47-year-old man with Behcet's disease presented with a five day history of right side weakness and dysarthria. Ten years ago, he was diagnosed as Behcet's disease. Since then, he was treated with low dose steroids. T1-weighted magnetic resonance images with gadolinium injection revealed ring enhancing lesions with internal hypointensities at the left side of the pons and at the left parietal cortex suggesting multiple metastatic tumors. Diffusion-weighted image and ADC map revealed central hyperintensity on diffusion with low ADC values at both lesions. The histopathology of stereotactic biopsy specimen showed frequent perivascular lymphocytic cuffings, focal necrotic lesions and reactive gliosis. The most common neuropathologic findings in neuro-Behcet's disease are focal necrotic lesions, but the location in cerebral cortex has not been reported before. Long term steroid therapy and antibiotics were administered and the patient recovered gradually. Neuro-Behcet's disease could be presented as brain tumor like lesion, and stereotactic biopsy should be considered in such situation.

A 51-year-old man with a diagnosis of myelodysplasia and non-Hodgkin's lymphoma underwent an unmatched allogenic bone marrow transplantation and was treated posttransplant with chronic immunosuppressive medication. Eight months following transplantation, he presented with progressive dysarthria, cognitive and visual decline. Evaluation included brain magnetic resonance (MR) imaging demonstrating multifocal areas of increased T2 and FLAIR (fluid attenuated inversion recovery) signals involving the left frontal, parietal, and occipital lobes. The MR lesions demonstrated diffuse increased signal on DWI (diffusion-weighted images) and normal to low signal on ADC (apparent diffusion coefficients). Contrast-enhanced T1 images were unremarkable. Lumbar puncture revealed a mild elevation in cerebrospinal fluid (CSF) protein. CSF PCR assay for viral DNA fragments were negative on two occasions. Serum serology for HIV was negative as well. A brain biopsy was subsequently performed. The clinical and neuroimaging differential diagnoses as well as neuropathologic correlation are presented.

The article represents a case of a young patient with atypical clinical and paraclinical presentation of vertebral artery dissection by multiple cerebral infarcts, localized at the supratentorial and infratentorial levels in the posterior circulation. A case of a 21-year-old man, without a history of trauma in the cervical area or at the cranial level, without recent chiropractic maneuvers or practicing a sport, which required rapid, extreme, rotational movements of the neck, was examined. He presented to the emergency room with nausea, numbness of the left limbs, dysarthria, and incoordination of walking, with multiple objective signs at the neurological examination, which revealed right vertebral artery subacute dissection after the paraclinical investigations. The case was particular due to the atypical debut symptomatology, through the installation of the clinical picture in stages, during 4 hours and by multiple infarcts through the artery-to-artery embolic mechanism in the posterior cerebral territory. Abbreviations: PICA = posterior inferior cerebellar artery, CT = computed tomography, MRI = magnetic resonance imaging, angio MRI = mangnetic resonance angiography, FLAIR = fluid attenuated inversion recovery, FS = fat suppression, ADC = apparent diffusion coefficient, DWI = diffusion weighted imaging, T1/ T2 = T1/ T2 weighted image-basic pulse sequences in MRI, VA = vertebral artery, 3D-TOF = 3D Time of Flight.
