We describe a 4-year-old girl with an inflammatory pseudotumour of the panc
reas, which was preceded by varicella-zoster infection. Inflammatory pseudo
tumour may involve a variety of tissues, the lungs and liver being typical
sites of predilection. Imaging and laboratory tests are nonspecific, and fo
r this. reason the diagnosis of inflammatory pseudotumour is rarely made pr
ior to surgery. These benign but locally aggressive masses simulate maligna
ncy in the majority of cases. Inflammatory pseudotumour should, therefore,
be considered when a mass arises in an unusual location in the paediatric a
ge group.
