BACKGROUND Tumefactive demyelinating lesions are a rare manifestation of multiple sclerosis (MS). Differential diagnosis of such space occupying lesions may not be straightforward and sometimes necessitate brain biopsy. Impaired cognition is the second most common clinical manifestation of tumefactive MS; however complex cognitive syndromes are unusual. CASE PRESENTATION We report the case of...

BACKGROUND Multiple sclerosis (MS) is less common in Asia, including Taiwan, and some characteristics of MS in Asians differ from those of Caucasians. Tumefactive brain lesion is even rarer in MS patients. OBJECTIVE To review patients with tumefactive MS and compare them with those in other studies investigating tumefactive demyelinating lesions and our Taiwanese typical MS patients. METHOD...

abstract background: a tumefactive lesion of central nervous system (cns) is defined as a mass-like lesion with a size greater than 2 cm in brain (magnetic resonance imaging) mri. neuroimaging may help to distinguish the nature of a tumefactive lesion and therefore can prevent an unnecessary brain biopsy. method: in this paper, we have emphasized on determining the nature of a cns tumefactive l...

We report a case of pathologically confirmed tumefactive multiple sclerosis (MS) followed shortly thereafter by the diagnosis of an oligoastrocytoma. The complexity of diagnosis and management of concomitant presence of tumefactive MS and glial cell tumors is discussed.

a young known case of multiple sclerosis was evaluated with chief complaint of gradually progressed left lower limb weakness over 3 weeks. pathologic examination of a mass in brain magnetic resonance imaging confirmed the diagnosis of glioblastoma multiforme (gbm). given the importance of the definite diagnosis of malignant glioma and its effect on patient’s management, gbm should be considered...

Tumefactive demyelinating lesion is defined as large solitary demyelinating lesion with imaging characteristics mimicking neoplasm. These atypical features include size more than 2 cm, mass effect, edema, and/or ring enhancement. Distinguishing tumefactive lesions from other etiologies of intracranial space occupying lesions is essential to avoid inadvertent surgical or toxic chemotherapeutic i...

Tumefactive demyelinating lesions are a rare presentation of multiple sclerosis (MS). Diagnosis of tumefactive is commonly carried out using magnetic resonance image (MRI). Tumefactive diagnosis is difficult because of may similar to the clinical and MRI characteristics of glioma or a cerebral abscess. We presented a 35-years-old female with one episode of secondary generalized seizure after de...

A tumefactive lesion of central nervous system (CNS) is defined as a mass-like lesion with a size greater than 2 cm in brain detected by magnetic resonance imaging (MRI). Neuroimaging may help to distinguish the nature of a tumefactive lesion and therefore, can prevent an unnecessary brain biopsy. Here we emphasized on determining the nature of a CNS tumefactive lesions with the help of MRI and...

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...

Balo's concentric multiple scleroses (MS) is a rare demyelinating disease and a variant of multiple sclerosis. We report a case with interesting misleading clinical history and typical RI findings of Balo disease. A 19-year-old girl presented with fever and left hemiparesis following dental procedure 15 days ago. On physical examination fever and left limbs forces loss were noted. On CT scan a ...
