Abstract
Chronic inflammatory lesions (CIL) in the body are rare and inflammatory pseudotumor (IPT) is a subtype of CIL. Spine is an uncommon location of CIL, with most cases reported in the thoracic spine. Our objective was to review the current literature on IPT. To the best of our knowledge only about 13 cases are reported till date. A retrospective review of 13 existing cases was done. The etiopathogenesis of CIL is uncertain and total surgical excision remains the mainstay. It's a diagnosis of exclusion after ruling out commonly found lesions, both clinically and radiologically. Only histopathology can confirm the diagnosis. Total surgical resection remains the mainstay of treatment with adjuvant treatment only if there is a residue or a recurrence. CILs are rare lesions in the body with IPT being the commonest. Surgical excision remains the mainstay of treatment and a long-term follow up is warranted.

Abstract
Pancreatic tumors in children are infrequently encountered in clinical practice. Their non-specific clinical presentation and overlapping imaging characteristics often make an accurate preoperative diagnosis difficult. Tumors are categorized as epithelial or non-epithelial, with epithelial tumors further classified as tumors of the exocrine or endocrine pancreas. Although both are tumors of the exocrine pancreas, solid pseudopapillary neoplasm is the most prevalent solid pancreatic tumor in children, while pancreatoblastoma is the most common malignant tumor. Insulinoma is the most common pediatric pancreatic tumor of the endocrine pancreas. Malignant tumors require a complete, often radical, surgical resection. However, pancreatic parenchyma-sparing surgical procedures are utilized for benign tumors and low-grade malignancy to preserve gland function. This review will discuss the epidemiology, pathophysiology, clinical and diagnostic characteristics, and management options associated with both common and rare solid pancreatic masses in children. We will also discuss current challenges encountered in their evaluation and treatment.

Abstract
BACKGROUND Pancreatic inflammatory myofibroblastic tumor (IMT) is a relatively rare disease that is often confused with pancreatic cancer or pancreatic neuroendocrine tumors. The histological features of IMTs show that tissue from this type of tumor contains an intermingling of fibroblast and myofibroblast proliferation, accompanied by a varying degree of inflammatory cell infiltration.
CASE SUMMARY The management of an IMT occurring at the neck of the pancreas is presented in this paper. A 66-year-old female patient was diagnosed with a pancreatic neck mass after a series of tests. The patient underwent enucleation of the pancreatic neck tumor after a pathological diagnosis of IMT. Previous research on the clinical features, pathological diagnosis and treatment of pancreatic IMTs was reviewed. Compared with previous reports, this is a unique case of enucleation of a pancreatic IMT.
CONCLUSION The enucleation of pancreatic IMTs may be a safe and efficient surgical method for managing such tumors with a better prognosis. Further cases are required to explore surgical measures for pancreatic IMTs.

Abstract
The inflammatory myofibroblastic tumor (IMT) is a rare stromal tumor with diverse imaging findings. The present study describes a case of contrast-enhanced CT and F-FDG PET/CT manifestations of an IMT with diffuse omental and mesenteric thickening and swelling in the entire abdominal cavity. It is extremely rare to observe such imaging features in the extrapulmonary IMT. Furthermore, this case emphasizes that F-FDG PET/CT holds the potential for demonstrating IMT lesion extent and correctly identifying appropriate sites for biopsy.

Abstract
CONTEXT Inflammatory myofibroblastic tumors are a rare type of soft-tissue tumor. Inflammatory myofibroblastic tumors are characterized by rearrangements involving the anaplastic lymphoma kinase gene locus on 2p23. CASE REPORT We report the case of a 67-year-old Chinese male who presented with dysuria and fever. Magnetic resonance imaging showed an irregular prostatic mass with an isointense signal and obscure boundary. Histopathological evaluation showed that the mass consisted mainly of spindle-shaped cells. Immunohistochemical evaluation showed that the tumor cells were negative for anaplastic lymphoma kinase. CONCLUSIONS Inflammatory myofibroblastic prostate tumors are rare lesions with unclear etiology. The pathological diagnosis is very important.

Abstract
RATIONALE Inflammatory myofibroblastic tumor (IMT) is a rare type of mesenchymal tumor. IMT can arise in multiple anatomic locations. IMT of the lumbar spinal canal is exceptionally rare. PATIENT CONCERNS Here, we report the case of a 56-year-old male patient with an IMT who was in good health until 1 year prior to admission, when he began experiencing pain in both lower extremities and the lower back. INTERVENTIONS A space-occupying lesion in the lumbar canal was identified by magnetic resonance imaging and then surgically resected. DIAGNOSES Histopathological analysis of the lesion revealed a composition of mucous edema, inflammatory cells, collagenous fibers, and spindle cells that were diffuse and positive for smooth muscle actin and CD68; focal positive for vimentin and desmin; and negative for CD34 (marker of vascular endothelial cells), CD21, CD23, CD35, S-100, Epstein-Barr virus infection, Ki-67, and anaplastic lymphoma kinase. Thus, the diagnosis was an IMT of the lumbar canal. OUTCOMES In the spinal canal, IMT should be considered in the evaluation of tumors although it is a very rare diagnosis. It is a benign lesion, but it has potential for invasion and recurrence. LESSONS There are no characteristic imaging features of these tumors, but they can be addressed by complete surgical excision. Patients with these lesions should undergo frequent long-term follow-up to detect and address recurrence.

Abstract
PURPOSE The aim of the study was to describe the clinical, radiographic, and pathologic features of inflammatory myofibroblastic tumor (IMT) to enhance the recognition of this rare disease. MATERIALS AND METHODS The clinical, imaging, and pathologic findings were retrospectively reviewed in 54 patients with IMT lesions, which were conformed by biopsy or surgical pathology. Of 54 patients, 51 had preoperative computed tomography (CT) examination and 13 had preoperative magnetic resonance imaging records. RESULTS The clinical appearances of these 54 patients had some relationship with the locations of lesions. Of 54 IMT patients, 87.0% cases (47/54) had solitary lesion. The mean long diameter of the lesions located at the sites of chest, abdomen, and pelvic regions was bigger than that of other locations (F = 3.025, P = 0.038). On plain CT images, soft tissue mass was found in all IMT lesions, except for 3 lesions that arose in the intestine tract, appearing as focal or diffuse thickening in the bowel wall. After contrast administration, all lesions were persistently enhanced; 72.7% cases (24/33) demonstrated heterogeneous enhancement with various cystic regions. Comparing the CT features with different anatomic lesions, ill-defined margin on the plain CT images and calcification were seen more frequently in the lesions of the head and neck (P = 0.010 and 0.035); however, the other radiological findings had no significant differences (all P > 0.05). Twelve of 51 IMT patients showed invasion into adjacent structures. On magnetic resonance imaging, 92.3% lesions (12/13) showed soft tissue masses demonstrating isointense to hypointense contrast compared with skeletal muscle on T1-weighted images and heterogeneously high signals on T2-weighted images; 85.7%(6/7) of lesions were heterogeneously enhanced with cystic changes. Immunohistochemistry showed that the percentage of positive staining for SMA, vimentin, anaplastic lymphoma kinase, CD68, CD34, CD99, B-cell lymphoma/leukemia-2, cytokeratin, Desmin, and S-100 protein were 88.9%, 87.0%, 44.4%, 59.3%, 53.7%, 29.6%, 42.6%, 28.5%, 13.0%, and 24.1%, respectively. CONCLUSIONS Inflammatory myofibroblastic tumor can involve any part of the body, and the clinical and radiological appearances are various owing to different anatomic sites. An ill-defined soft tissue mass heterogeneous enhancement with or without invasion into adjacent structures on computed tomographic or magnetic resonance images and positive staining for SMA and vimentin on immunohistochemical examination could suggest the diagnosis.

Abstract
BACKGROUND Inflammatory 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 REPORTS In this report, we present different and rare CT manifestations of three adult patients with lung IMT. CONCLUSIONS In 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.

Abstract
Inflammatory myofibroblastic tumors (IMTs) of the inguinal region are exceptionally rare. The current study reported the case of a 49 year-old male patient with IMT, who presented with a fever, night sweats, anorexia, loss of weight and frequent urination. Computed tomography (CT) revealed a lesion occupying the soft tissue of the right inguinal region and surgery was performed to resect the lesion. Histopathological analysis of the lesion revealed a composition of spindle and inflammatory cells, including plasma cells and lymphocytes. In addition, immunohistochemical analysis demonstrated that the tumor cells were positive for CD34, vimentin, actin, Ki-67, B cell lymphoma-2, CD99, epithelial membrane antigen and CD38; however, tumor cells were negative for CD117, desmin, anaplastic lymphoma kinase and creatine kinase. Thus, the patient was diagnosed with IMT and was advised to return for regular follow-up appointments. Subsequently, the patient developed a local recurrence 12 months following the initial surgery. Of note, the histopathological characteristics of the recurrent lesions were consistent with those of the initial specimen. Thus, a second surgery was performed, followed by fractionated radiotherapy (FRT). At 3 and 6 months following the FRT, magnetic resonance imaging scans did not indicate tumor recurrence or metastasis. In conclusion, surgical excision is the current recommended treatment for IMT; however, for cases similar to that of the current study, which are not successfully controlled by surgical excision, radiotherapy should be considered and long-term follow-up is essential.

Abstract
BACKGROUND Inflammatory myoblastic tumors (IMTs) are rare, mesenchymal neoplasms most commonly located in areas of previous inflammation. In the temporal bone, these tumors typically present as solitary, space-occupying lesions that clinically resemble chronic otitis media. METHODS We present a case of bilateral IMTs with facial nerve involvement, sigmoid sinus thrombosis, leptomeningeal enhancement, and seizures. RESULTS/CONCLUSION This case demonstrates the need for a high index of suspicion of IMT when imaging reveals bilateral mastoid opacification. These tumors are more aggressive than their orbital counterparts and require multimodality therapy to prevent recurrence and alleviate severe neurotologic symptoms.
