PANDAS Syndrome (Paediatric Autoimmune Neuropsychiatric Disorders Associated 
with Streptococcus) is a rare disease described in 1998. In this disease, there 
is a relationship between group A beta haemolytic streptococcal tonsil 
infections and the exacerbation of neuropsychiatric disorders. A case report of 
a 9-year-old child with PANDAS syndrome is presented. This child has had no 
further symptoms after tonsillectomy. The understanding about PANDAS syndrome 
and tonsillectomy is reviewed.
