Lipomatous tumors are among the most common primary musculoskeletal neoplasms affecting both pediatric and adult patient populations. Patient age, tumor location, and imaging features all contribute to the differential diagnosis of musculoskeletal tumors. Tumors identified outside of common patient demographics or in unusual locations may lead to preoperative misdiagnosis. We present an uncommon adipocytic tumor occurring at an uncommon age which was proven at surgery to represent a preoperatively unexpected diagnosis. A 13 year old male presented with a fatty anterior proximal thigh mass; age and magnetic resonance findings suggested lipoblastoma. However, following complete surgical resection, histopathology confirmed hibernoma, a benign lipomatous tumor characterized by the presence of white and multivacuolated brown fat cells, the vast majority of which occur in adult patients.

Introduction: Ischial lesion is considered rare. Aim: In this study, we review the patient demographics, imaging appearances, and pathological entities which arise in the ischium with the aim of facilitating a differential diagnosis. This allows appropriate management to be instigated in a timely fashion, enabling lesion to be stratified into those that can be managed locally or referred to a specialist center. Materials and Methods: A retrospective search of our oncology and radiology database was performed to identify primary ischial lesions. Results: The search revealed 82 cases with primary involvement of ischium. The most common benign tumor was aneurysmal bone cyst in patients under 40 years and osteochondroma in patients over the age of 40 years. Metastasis was the most common malignant tumor in both cohorts (<40 years and over 40 years). Conclusion: We present the patient demographics, imaging appearances of pathological entities which arise in the ischium with the aim of facilitating a differential diagnosis.

Head and neck tumors are rare in pediatric patients but should be kept in the differential when a patient presents with a new swelling or mass. One of these tumors is a myxoma, which is an insidiously growing, benign mass originating from the mesenchyme. They most commonly arise in the myocardium but can also develop in facial structures, particularly in the maxilla and mandible. When arising in facial structures, ocular, respiratory, and digestive systems can be affected based on local invasion. Complete surgical resection is curative but can lead to significant morbidity as well. Here, we present a case of a 15-month-old toddler presenting with a paranasal mass, which was ultimately diagnosed as a maxillary myxoma. This tumor is very rare in the pediatric population, especially in the toddler age-group, reminding clinicians to broaden the differential diagnosis when a patient’s course is atypical.

Abstract Coronavirus disease-19 (COVID-19) is only one of the many possible infectious and non-infectious diseases that may occur with similar imaging features in patients undergoing [18F]-fluorodeoxyglucose (18FDG) monitoring, particularly in the most fragile oncologic patients. We briefly summarise some key radiological elements of differential diagnosis of interstitial lung diseases which, in our opinion, could be extremely useful for physicians reporting 18FDG PET/CT scans, not only during the COVID-19 pandemic, but also for their normal routine activity.

Extraosseous Ewing’S Sarcoma

AbstractExtraosseous Ewing’s sarcoma (EES), first described in 1969, is a malignant mesenchymal tumor just like its intraosseous counterpart. Although Ewing’s sarcomas are common bone tumors in young children, EESs are rarer and more commonly found in older children/adults, often carrying a poorer prognosis. We discuss the multimodality imaging features of EES and the differential diagnosis of an aggressive appearing mass in proximity to skeletal structures, with pathologic correlates. This review highlights the need to recognize the variability of radiologic findings in EES such as the presence of hemorrhage, rich vascularity, and cystic or necrotic regions and its imaging similarity to other neoplasms that are closely related pathologically.

Soft Tissue Masses

Inflammatory pseudotumours are uncommonly encountered lesions in the abdomen and pelvis that often present with variable and nonspecific imaging features. They may mimic other more common lesions, including malignancy. Within the appropriate clinical context, inflammatory pseudotumours merit consideration in the differential diagnosis of soft-tissue masses within the abdomen and pelvis. A preoperative diagnosis of inflammatory pseudotumour, established through biopsy, may help to differentiate this benign entity from malignancy. In this article, we reviewed the imaging features of inflammatory pseudotumours of the abdomen and pelvis, including liver, spleen, bowel, retroperitoneum, kidney, bladder, uterus, and adnexa.

ObjectiveTo investigate the diagnostic performance of contrast-enhanced ultrasound (CEUS) in the differentiation of primary thyroid lymphoma (PTL) and nodular Hashimoto’s thyroiditis (NHT) in patients with background of heterogeneous diffuse Hashimoto’s thyroiditis (HT).MethodsSixty HT patients with 64 thyroid nodules (31 PTL and 33 NHT) who had undergone CEUS examination were included in this study. With histopathological results as the reference, we evaluated the imaging features of each nodule on both conventional ultrasonography (US) and CEUS. Quantitative CEUS parameters including peak intensity (PI), time to peak (TTP), and area under the time–intensity curve (AUC) were gathered in the nodule and background parenchyma. The ratio indexes of theses parameters were calculated by the ratio of the lesion and the corresponding thyroid parenchyma. Logistic regression and receiver operating characteristic (ROC) curves analyses of valuable US indicators were further preformed to evaluate the diagnostic capability of CEUS in discrimination of PTL and NHT.ResultsAmong all the observed US imaging features and CEUS parameters, 10 indicators showed significant differences between PTL and NHT (all P &lt; 0.05). All the significant indicators were ranked according to the odds ratios (ORs). Eight of them were CEUS associated including imaging features of enhancement pattern, degree, homogeneity, and quantification parameters of PI, AUC, ratios of PI, AUC, and TTP, while indicators on conventional US, including vascularity and size ranked the last two with ORs less than 3. The five single CEUS parameters showed good diagnostic performance in diagnosis of PTL with areas under ROC curves of 0.72–0.83 and accuracies of 70.3–75.0%. The combination of CEUS imaging features and the ratios of PI, AUC, and TTP demonstrated excellent diagnostic efficiency and achieved area under ROC curve of 0.92, which was significantly higher than any of the five single parameters (all P &lt; 0.05), with a sensitivity of 83.9%, specificity of 87.9%, and accuracy of 85.9%.ConclusionsCEUS is an efficient diagnostic tool in the differential diagnosis of PTL and NHT for patients with diffuse HT. Conjoint analysis of CEUS imaging features and quantification parameters could improve the diagnostic values.

ABSTRACT Giant multilocular prostatic cystadenoma (GMPC) is a rare benign pelvic mass for which complete surgical resection is an accepted treatment of choice. This report presents the first case of complete resolution of GMPC following a 3-year course of luteinising hormone-releasing hormone agonist alongside external beam radiotherapy for the concurrent treatment of unfavorable intermediate-risk prostate cancer. In addition to illustrating the imaging features of the effect of androgen deprivation therapy (ADT) and radiotherapy on GMPC regression, this case provides evidence for considering ADT as an alternative, noninvasive GMPC treatment option in patients in whom surgical treatment is either contraindicated or can be made less invasive by reducing the size of GMPC prior to its removal.

Large vallecular masses are an uncommon disease entity which includes a wide spectrum of rare pathologies. These masses may present as purely vallecular in location or appear as an extension from adjacent anatomical sites like tongue base including lingual tonsils, epiglottis, palatine tonsils, epiglottis, and the remainder of supraglottis. Literature review reveals very rare conditions presenting as vallecular mass lesions. The imaging features are generally diagnostic for characterization. However, these masses can exhibit indeterminate appearance at imaging. We present a series of five cases which includes two rare presentations: a case of low-grade cribriform adenocarcinoma of the base of tongue and a vallecular lipoma. The other three cases presented for differential diagnosis including benign vallecular cysts and two cases to show that malignant masses arising from neighboring anatomical sites such as tongue base or supraglottic larynx can exhibit significant vallecular component.
