Inflammatory Myofibroblastic Tumour (IMT) of pancreas is a rare benign mesenchymal neoplasm with a predilection for lung and abdomino-pelvic region. Other sites of occurrence are orbit, peritoneum, mesentery, and pancreas. In children about one-third cases were seen in lung and two-thirds extrapulmonary sites.1 These tumours were previously known as inflammatory pseudotumour because on histopathological examination consists of myofibroblastic and fibroblastic proliferation with an inflammatory infiltrate.2 This tumour was first described in the lung, and very rare in pancreas.3 It is mostly seen in children and young adults with a worldwide prevalence rate of 0.04%-0.7%. 4,5
