Tumefactive multiple sclerosis

Romanian Neurosurgery, 2021
Tumefactive multiple sclerosis is a rare variant of multiple sclerosis, characterized by the presence of brain lesions that may be solitary or multiple. Considering that these lesions have a pseudotumoral appearance, it is a challenge to differentiate them from central nervous system neoplasms through neuroimaging.

Neuromyelitis Optica Mimicking Multiple Sclerosis: A Case Report and a Comprehensive Review of the Literature

Clinical Case Reports, Volume 13, Issue 10, October 2025.
Post‐gadolinium enhancement of the spinal cord seen in NMO. ABSTRACT Neuromyelitis optica spectrum disorder (NMOSD) may mimic other neurological conditions, including multiple sclerosis (MS). We report a 25‐year‐old woman with hypothyroidism and depression who presented with progressive quadriparesis.

Durable Response to Pazopanib (Tyrosine Kinase Inhibitor) in a Patient With EWSR1::CREM Gene Fusion Positive Intra‐Abdominal Unclassified Epithelioid Sarcoma

Genes, Chromosomes and Cancer, Volume 64, Issue 10, October 2025.
ABSTRACT EWSR1::CREM fusion positive intrabdominal sarcomas defines a rare emerging group of aggressive mesenchymal neoplasms with a predilection for the celomic cavity and often manifesting perplexing immunophenotypic profile. There is no specific standard of care therapeutic option though anecdotal reports response to pazopanib have been reported. We

Cerebral tumefactive demyelinating lesions

Oncology Letters, 2015
Tumefactive demyelinating lesions (TDLs), are a rare demyelinating pathological disease in the central neurological system, which have been proven to be a diagnostic dilemma to neurosurgeons. The clinical presentation and radiographic appearance of these lesions often results in their misdiagnosis as intracranial tumors, such as gliomas, which leads to

IgG4‐Related Disease: Emerging Roles of Novel Genetic Variants, Immune Cell Subsets and Therapeutic Targets

Allergy, Volume 80, Issue 10, Page 2738-2754, October 2025.
ABSTRACT IgG4, the least abundant IgG subclass in humans, is increasingly recognised for its involvement in allergic and autoimmune pathologies. Its unique properties, such as the tendency to form half‐molecules (one heavy chain and one light chain) and its generally non‐inflammatory nature, distinguish it from other IgG subclasses.

Malignancies and IgG4‐related disease

Rheumatology &Autoimmunity, Volume 5, Issue 3, Page 161-173, September 2025.
Immunoglobulin G4‐related disease (IgG4‐RD) is associated with increased cancer risk. Malignancies affect both IgG4‐RD involved organs, such as the lung, pancreas, bile duct, and prostate, and noninvolved organs, such as the gastrointestinal duct. B‐cell neoplasms constitute a proportion of the malignancies linked to this disease.

Potential roles of antibodies with different classes in IgG4‐related diseases

Rheumatology &Autoimmunity, Volume 5, Issue 3, Page 174-185, September 2025.
This review discussed the common characteristics of different classes of antibodies and their potential corresponding unique mechanisms involved in immunoglobulin G4‐related disease. Abstract Immunoglobulin G4‐related disease (IgG4‐RD), first identified two decades ago, is an immune‐mediated pro‐inflammatory and profibrotic disease entity affecting ...
