A 16-month-old boy presenting with a previous two-month history of absences, was admitted
for partial seizures and vomiting. Magnetic resonance imaging revealed a left temporo-occipital
intraparenchymatous, well circumscribed lesion. Complete macroscopic resection was
performed. Morphological and immunohistochemical analyses were conclusive for an inflammatory
pseudotumour. Only a few cases of intracranial locations of this entity have been
reported. Our case is the first described in an infant younger than four years of
age. This observation suggests that chronic evolution may start earlier than thought
in adult cases, perhaps due to an autoimmune process.
