Cerebral aspergilloma in a child with autosomal recessive chronic granulomatous disease

A 2 year old girl presented with epilepsy 16 months after being diagnosed as having autosomal recessive chronic granulomatous disease. Computed tomography showed a cerebral mass which was surgically removed and proved histologically to be an aspergilloma. This case illustrates the application of molecular diagnostic techniques to the diagnosis of chronic granulomatous disease. The occurrence of, and unusual reaction to, cerebral aspergillus infection indicates the need to consider this possibility in the differential diagnosis of mass lesions in chronic granulomatous disease. Furthermore, it is clear that autosomal recessive chronic granulomatous disease cannot be considered to be a clinically mild form that is exempt from major neurological complications.
