Susac's syndrome, a rare, potentially severe or lethal neurological disease.
Summary of "Susac's syndrome, a rare, potentially severe or lethal neurological disease."
Susac's syndrome (SS) is a rare, immune-mediated endotheliopathy affecting the microvasculature of the brain, the inner ear and the retina. Clinical presentation is characterised by a triad: encephalopathy, hearing loss and branch retinal artery occlusion (BRAO). Given the rarity of this disease, its natural history still remains partially unknown, but lethal cases appear to be extremely rare since there has never been, to our knowledge, a report of SS leading to death. We report 2 cases of SS illustrating the multiplicity of neurological symptomatology and its unpredictable course. One case is particularly unusual due to its severe neurological evolution, leading to death despite treatments. This report presents clinical and paraclinical findings contributory to SS diagnosis and offers an innovative perspective on disease management. These cases represent the potential severity of this disease. Early, aggressive treatment strategies may be warranted for SS in order to avoid neurological deterioration and lethal evolution.

A rare disorder consisting of microangiopathy of brain, retina, and inner ear ARTERIOLES. It is characterized by the clinical triad of encephalopathy, BRANCH RETINAL ARTERY OCCLUSION and VERTIGO/hearing loss.
An inherited neurological developmental disorder that is associated with X-LINKED INHERITANCE and may be lethal in utero to hemizygous males. The affected female is normal until the age of 6-25 months when progressive loss of voluntary control of hand movements and communication skills; ATAXIA; SEIZURES; autistic behavior; intermittent HYPERVENTILATION; and HYPERAMMONEMIA appear. (From Menkes, Textbook of Child Neurology, 5th ed, p199)
Rare autosomal recessive syndrome of extreme insulin resistance due to mutations in the binding domain of INSULIN RECEPTOR. Clinical features include severe intrauterine and postnatal growth restriction, characteristic dysmorphic FACIES; HIRSUTISM; VIRILIZATION; multiple endocrine abnormalities, and early death.
A rare transmissible encephalopathy most prevalent between the ages of 50 and 70 years. Affected individuals may present with sleep disturbances, personality changes, ATAXIA; APHASIA, visual loss, weakness, muscle atrophy, MYOCLONUS, progressive dementia, and death within one year of disease onset. A familial form exhibiting autosomal dominant inheritance and a new variant CJD (potentially associated with ENCEPHALOPATHY, BOVINE SPONGIFORM) have been described. Pathological features include prominent cerebellar and cerebral cortical spongiform degeneration and the presence of PRIONS. (From N Engl J Med, 1998 Dec 31;339(27))
A rare, X-linked mental retardation syndrome that results from mutations in the RIBOSOMAL PROTEIN S6 KINASE gene. Typical manifestations of the disease include an intelligence quotient of less than 50, facial anomalies, and other malformations.
