A confusing lesion: pulmonary Inflammatory Myofibroblast Tumour

Inflammatory Myofibroblastic Tumours (IMT), also known as plasma cell granuloma, is a mesenchymal neoplasm that can be observed in almost every tissue. IMT is very rare with an incidence of approximately 0.04-1% of all pulmonary masses in adults. In children, it is the most common primary mass of the lung. Imaging findings of IMT are variable and nonspecific, probably due to fibrosis and cellular infiltration. They can cause difficulties in the diagnostic process due to differences in imaging characteristics.
