Cerebral mass-like lesion (MLL) is a rare form of Neuro-Behçet's (NB) disease. There is currently no detailed knowledge on this issue in the literature. Our aim was to describe a Behçet's disease (BD) patient with MLL, followed by a clinical analysis in light of the available literature regarding BD patients who suffered from an MLL or tumefactive lesion in the brain. We conducted a review of t...

INTRODUCTION In rare instances, demyelinating disorders manifest as tumefactive lesions that simulate brain tumors. We report a patient with a space-occupying lesion in the parietal lobe, which presented a serious diagnostic dilemma, between a rare tumefactive demyelinating disease, such as Balo concentric sclerosis and a glioma. This case report highlights important diagnostic clues in the dif...

Background: A demyelinating lesion can present as a space occupying in Magnetic Resonance Imaging (MRI) brain. Lesions that have diameter greater than 2 cm is referred tumefactive lesion. These lesions mimic brain tumor, namely glioma or primary central nervous system lymphoma. Case presentation: We two female patients over 30 years old who presented with limb weakness. Their MRI demonstrated t...

BACKGROUND AND PURPOSE Multiple sclerosis (MS) plaques appear as well-demarcated, homogenous small ovoid lesions on magnetic resonance imaging (MRI). Atypical radiographic features of MS lesions include size greater than 2 cm, mass effect, and edema. Tumefactive MS lesions can radiographically mimic intra-cranial neoplasms, infarction, as well as infections. In atypical cases of tumefactive dem...

The cooccurrence of multiple sclerosis (MS) and oligodendroglioma is very rare. We present a 43-year-old male patient with the diagnosis of MS lasting for 14 years who developed seizures and right hemiparesis; cerebral MRI revealed an already known extensive lesion, previously misdiagnosed as tumefactive demyelinating lesion. Cerebral biopsy leads to oligodendroglioma diagnosis, successfully tr...

Multiple sclerosis (MS) is the most common inflammatory demyelinating disease, affecting approximately one million adults worldwide. This paper describes a young female patient who presented to the acute medical team with generalised tonic-clonic seizures and right hemiplegia on a background of MS. Radiological imaging revealed a large ring enhancing lesion exerting mass effect. We describe an ...

Brain MR imaging abnormalities in primary Sjögren syndrome (pSS) are generally discrete white matter lesions. We describe a 50-year-old woman with recurrent neurologic deficits. MR imaging revealed a large brain lesion. A diagnosis of pSS was made on the basis of clinical features, positive anti-Ro and anti-La antibodies, abnormal Schirmer test findings, and salivary gland scintigraphy. The pat...

T umefactive demyelinating lesion (TDL) is defined as a solitary de myelin ating lesion greater than 2 cm. Mass effect and contrast enhancement on neuroimaging make it difficult to distinguish this type of lesion from high-grade gliomas. Multiple sclerosis (MS) accounts for most cases of TDL. Even in patients with established MS, an atypical manifestation of a large lesion can suggest concurren...
