A 42-year-old woman was admitted for a complex partial seizure. At age 18 years, she had transient diplopia, which was considered a simple strabismus. Current examination revealed a left VI cranial nerve palsy and right arm hyperreflexia. Neuroimaging showed multiple intraparenchymal cystic lesions in white matter (figure), multiple calcifications in basal ganglia, and extensive bilateral leuko...

We report a case of presumed vacuolating megalencephalic leukoencephalopathy (VML) in a 5-year-old boy that was diagnosed when the patient was 34 months old. The patient presented clinically with megalencephaly and delayed onset of slowly progressive neurologic dysfunction. Serial MR imaging and biochemical analysis were performed to differentiate VML from other disease entities with megalencep...

Acute toxic leukoencephalopathy (ATL) is a rare adverse effect of 5-Fluorouracil (5-FU) chemotherapeutic agent. It is imperative for the radiologist to confidently identify the white matter changes caused by this agent in case of toxicity. This will help in early detection and appropriate management of patient, as the condition is reversible both clinically and on imaging. We report a case of a...

UNLABELLED INTRODUCTION Reversible posterior leukoencephalopathy syndrome - a reversible subacute global encephalopathy clinically presenting with headache, altered mental status, visual symptoms such as hemianopsia or cortical blindness, motor symptoms, and focal or generalized seizures - is characterized by a subcortical vasogenic edema symmetrically affecting posterior brain regions. Comp...

The main aim of the study is to evaluate efficacy and safety profile Ocrelizumab (OCR), Rituximab (RTX), Cladribine (CLA), employed as Natalizumab (NTZ) exit-strategies in Relapsing-Remitting Multiple Sclerosis (RRMS) patients at high-risk for progressive multifocal leukoencephalopathy (PML).
