“…peripheral, punctate or fine) are seen in 15% of IMTs. However, calcification is very rare in adult IMTs [ 12 ]. We observed three different manifestations of IMT, namely cavitation in case 1, densely calcified perihilar mass in case 2, and consolidative mass lesion in case 3.…”

SummaryBackgroundInflammatory myofibroblastic tumor (IMT), also known as inflammatory pseudotumor, is a benign disorder composed of fibrous tissues, myofibroblasts and inflammatory cell proliferation with obscure etiology. Although it is the most common lung tumor in children, it is seen rarely in adults constituting less than 1% of adult lung tumors.Case ReportsIn this report, we present different and rare CT manifestations of three adult patients with lung IMT.ConclusionsIn conclusion, IMT is a rare lung tumor in adults and may simulate malignancy. It should be considered in the differential diagnosis when a large mass with lobulated contour or harboring coarse calcification is observed.

“…A study based on next-generation sequencing (NGS) assays reported that two of nine ALKnegative patients harbored PDGFRβ kinase fusions, and four of them harbored ROS1 kinase fusions, suggesting that IMT is likely a kinase fusion-driven tumor (24). Clinically, it is very difficult to distinguish pulmonary IMT from lung cancer (25). The clinical manifestations of IMT are not specific.…”

Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor. Although IMT generally exhibits benign biological behavior, some IMT patients may develop local recurrence or even distant metastasis. Surgery is the most common therapeutic approach. However, additional treatment options are necessary for those who are unable to undergo surgical treatments. Microwave ablation (MWA) is a developing treatment option for unresectable lung cancer. Compared with radiofrequency ablation (RFA), MWA possesses many advantages including larger ablation zones, shorter heating times, and less susceptibility to heat sink. Herein, we reported the case of an 80-year-old male patient who presented with a mass in the right lower pulmonary lobe and right pleural effusion. The maximum diameter of the mass was 53.76 mm, and the patient's main complaint was fatigue for 2 months. Blood test showed severe anemia (hemoglobin: 79 g/L) and hypoproteinemia (albumin: 27.7 g/L). After undergoing blood transfusion, supplementation of albumin, thoracical puncturing and piping, the patient's nutritional condition was improved (hemoglobin, 95 g/L; serum albumin, 29.9 g/L). The pathological diagnosis was pulmonary IMT by percutaneous lung biopsy. The patient was successfully treated with three rounds of percutaneous MWA and has no evidence of recurrence nearly 3 years later. This case has expanded the therapeutic options for elderly patients with pulmonary IMT. Percutaneous MWA monotherapy might serve as an emerging treatment strategy for medically inoperable patients.

“…IMTs have been observed predominantly in young patients and have been encountered virtually in any anatomical location such as the lungs [2], mesentery [4], omentum [3], retroperitoneum [5], extremities [6], head [7], liver [10], spleen [11], thyroid [12], and urinary bladder [13]. Notably, reported cases on IMTs/IPTs of the breast are very scarce [1, 9, 14–34].…”

“…Inflammatory myofibroblastic tumors have largely been considered as a subgroup of inflammatory pseudotumors [1] and have been encountered in various anatomical locations [2–7]. Interestingly, mammary IMTs have scarcely been reported.…”
