What is congenital intrauterine infection-like syndrome?
Congenital intrauterine infection-like syndrome is characterised by the presence of microcephaly and intracranial calcifications at birth accompanied by neurological delay, seizures and a clinical course similar to that seen in patients after intrauterine infection with Toxoplasma gondii, Rubella, Cytomegalovirus, Herpes simplex (so-called TORCH syndrome), or other agents, despite repeated tests revealing the absence of any known infectious agent.
How common is congenital intrauterine infection-like syndrome?
Congenital intrauterine infection-like syndrome is extremely uncommon. Only more than 30 cases have been described in the literature so far. Please discuss with your doctor for further information.

How is congenital intrauterine infection-like syndrome diagnosed?
Diagnosis relies on the clinical picture and requires exclusion of intrauterine infections.
Congenital intrauterine infection-like syndrome shows considerable clinical overlap with Aicardi-Goutieres syndrome (AGS). The two syndromes were reported to differ by the presence of cerebrospinal fluid anomalies (CSF leucocytosis and elevated IFN-alpha levels) in AGS and hepatic dysfunction, congenital microcephaly and thrombocytopaenia in congenital intrauterine infection-like syndrome. However, as the clinical manifestations of both syndromes show significant variability, it has been suggested that AGS and congenital intrauterine infection-like syndrome represent different presentations of the same disease. The differential diagnosis should also include other syndromes characterised by microcephaly and intracranial calcification such as Cockayne syndrome, COFS syndrome (which is usely considered as the neonatal form of Cockayne syndrome) and Hoyeraal-Hreidarsson syndrome (the neonatal presentation of dyskeratosis congenita syndrome; see these terms), some cases of mitochondrial encephalomyopathy, and pseudohypoarathyroidism. Ancient cases may have been reported as “Fahr disease”, an outdated, causally heterogeneous clinical entity that encompasses several entities with intracranial calcifications.
How is congenital intrauterine infection-like syndrome treated?
Treatment is symptomatic only. The prognosis is variable but can be severe with several of the reported patients dying within the first year of life.
