A Unique Case of Radiologically Isolated Syndrome Diagnosed During a Follow-up of Cytomegalovirus Meningoencephalitis.

Radiologically isolated syndrome (RIS) refers to an entity in which an MRI of the brain, spine, or both demonstrates incidental white matter lesions that are characteristic of a demyelinating disease in morphology and location. High-risk RIS may require disease-modifying treatment (DMT). A complex interaction among genetic and environmental factors leads to self-reactive immune mechanisms, which are believed to have a pivotal role in the pathogenesis of demyelinating diseases.

A Rare Case of Cerebral Fat Embolism With No Respiratory or Dermatologic Involvement.

Fat embolism syndrome is potentially lethal. It is frequently a complication of long bone fractures and/or orthopedic surgery. Cerebral fat embolism is an unusual condition characterized by purely cerebral involvement.

Hemiballismus Secondary to Metastatic Lung Cancer: A Case Report.

Anti-Ri-Associated Paraneoplastic Neurological Syndrome Revealing Breast Cancer: A Case Report.

Neurological paraneoplastic syndromes are a rare entity that affects patients with cancer. Anti-Ri antibodies affect the brain stem and produce a heterogeneous rapidly progressive subacute syndrome depending on the involvement of the different regions concerned. The most common clinical presentation is opsoclonus-myoclonus syndrome and paraneoplastic cerebellar degeneration.

Cerebral fat embolism syndrome after long bone fracture: A case report.

Cerebral fat embolism is a rare and potentially fatal condition that may occur following a long bone fracture. Its characterized by respiratory, neurological, and mucocutaneous signs. Isolated severe brain syndrome remains exceptional.

Gayet-Wernicke Encephalopathy: An Unusual Complication of Vomiting.

Gayet-Wernicke encephalopathy (WE) is a serious and acute disease of the central nervous system caused by thiamine (vitamin B1) deficiency. Multiple etiologies are indicated, although alcohol abuse is the most reported cause. If not treated promptly, WE can lead to serious complications such as Korsakoff's syndrome, coma, or death.
