Lack of progression of brain atrophy in Aicardi-Goutières syndrome

Abstract

Aicardi-Goutières syndrome is a severe and progressive familial encephalopathy that is characterized by acquired microcephaly, intracranial calcification (mainly of the basal ganglia), signs of white matter disease, and chronic lymphocytosis with elevated levels of interferon-alpha in the cerebrospinal fluid in the absence of other evidence of infection. Although the degree of calcification and the severity of brain atrophy are variable, typically the brain lesions appear to progress on successive examinations. In this article a 4-year-old male patient with Aicardi-Goutières syndrome who manifested the typical neurologic signs of the disease was re-evaluated. The evaluation revealed, on successive cranial computed tomography and magnetic resonance imaging scans, increasing calcification with remarkable reduction of brain atrophy. To the best of our knowledge, there is only one previously mentioned study of a 4-year-old female patient with progressive features of Aicardi-Goutières syndrome, including intracranial calcification, who displayed a lack of progression of brain atrophy at MRI scan.
