Demyelinating lesions of the brain have been frequently reported to mimic tumors, whereas very few cases of tumefactive demyelination of the spine have been reported. We report a patient with tumefactive demyelination of the spinal cord who was clinically, by MRI, and by frozen section diagnosed with tumor and had complete surgical resection. Hence patients with spinal cord lesions suspicious o...

BACKGROUND Tumefactive multiple sclerosis (MS) is an unusual variant of demyelinating disease characterized by lesions with pseudotumoral appearance on radiological imaging mimicking other space-occupying lesions, such as neoplasms, infections, and infarction. Especially when the patient's medical history is incompatible with MS, the differential diagnosis between these lesions constitutes a di...

Objective: A 65-year-old man presented with a nine-month history of swelling in the midline of the forehead. After surgical intervention, this lesion was found to be a tumefactive fibroinflammatory lesion of the frontal sinus. This case report and review aims to report this new location for tumefactive fibroinflammatory lesion, and to discuss whether, in retrospect, there would have been altern...

Whether or not recurrent tumefactive demyelinating lesions are a unique form of CNS demyelinating disease or part of the continuum of multiple sclerosis is a question raised by the case report on which this commentary is based. Detailed review and immunopathologic study of biopsy material may not only confirm or refute a diagnosis of demyelinating disease, but potentially uncover unique feature...

We present two cases of focal, tumefactive, masslike lesions of diffuse cerebral amyloid angiopathy (CAA) that presented as areas of increased signal intensity on long TR sequences without contrast enhancement or restricted diffusion. MR spectroscopy revealed normal metabolite ratios and unremarkable spectra. Pathologic tissue showed CAA and CAA with angitis of the CNS. Tumefactive CAA is a rar...

ABSTRACT Tumefactive fibroinflammatory lesions are rare idiopathic benign fibrosclerosant that clinically and radiologically simulate malignancy. These have a high recurrence rate, so patients should be monitored for the long term. We present case of 87 years old patient who came to emergency room with 1-month history an expansive maxilary lesion. A biopsy was performed result tumefactive

Magnetic resonance imaging (MRI) is likely to play an increasing role in efforts to understand the earliest changes in multiple sclerosis (MS) and narrowing the gap to new insights provided by the recent pathology literature showing early meningeal and cortical inflammatory disease and cortical gray matter demyelination. Much of the insight into early MS already comes from MRI as it evaluates p...

Neuromyelitis optica spectrum disorder (NMOSD) is a diverse condition which not only encompasses isolated longitudinally extensive transverse myelitis (LETM) and optic neuritis but also includes area postrema syndrome, acute brainstem syndrome, symptomatic narcolepsy or acute diencephalic clinical syndrome, and symptomatic cerebral syndrome. Imaging may reveal periependymal lesions surrounding ...
