EXTRAPULMONARY INFLAMMATORY PSEUDOTUMOR IN CHILDREN

Inflammatory pseudotumor (IPT), an unusual etiology of an intraabdomin al mass, is typically heralded by fever, anemia, thrombocytosis, and s ystemic symptoms that bear a resemblance to an inflammatory diathesis. Two cases of IPT seen within a 1-year period are presented: an adrena l IPT simulating a neuroblastoma was seen in an 8-year-old girl, and I PT in the jejunal mesentery mimicked a sarcoma in a 9-year-old boy. Al though IPTs are histologically benign, they can be locally aggressive and often mimic a malignancy both radiographically and grossly, This d iagnosis is rarely considered in the differential diagnosis of an abdo minal mass.
