“…evaluated 6 patients of Askin tumor with 18 F-FDG PET and observed that the lesion SUV max varied from 4.0 to 18.6. [ 8 ] However, Kara Gedik et al . reported a SUV max of 4.3 in their case report of 73-year-old male with Askin tumor.…”

“…Elevated catecholamine levels seen in neuroblastoma differentiate it from Askin tumor [6] . In addition, neuroblastomas are known to have early enhancement, invade surrounding vasculature, and in contradistinction to the typical Askin tumors, may show coarse calcifications [7] .…”

“…Vascular enhancement after intravenous gadolinium may occur and indicates neoplastic hypervascularity [1] . Fluorodeoxyglucose-positron emission tomography/CT may also help provide clarification, as Askin tumors have presented as fluorodeoxyglucose-avid masses [7] . Nevertheless, no set of imaging characteristics are pathognomonic for Askin tumors.…”

A 53-year-old male with no significant past medical history presented with an acute traumatic fracture of his thumb. Preoperative chest radiograph before K-wire fixation demonstrated an incidental 9 cm opacity of the left lung. Chest computed tomography revealed a 6.3 cm aggressive appearing pleural-based mass with erosion and destruction of the underlying rib. The patient underwent percutaneous biopsy with interventional radiology, and pathology revealed a small round blue cell tumor with positive CD99 staining and a FUS-ERG chromosomal translocation. The patient was diagnosed with Askin tumor, a peripheral primitive neuroectodermal tumor of the thoracopulmonary region belonging to the Ewing sarcoma tumor family. Computed tomography and magnetic resonance imaging of Askin tumors may show features such as a heterogeneous soft tissue mass, pleural effusion, rib destruction, hemorrhage, necrosis, and cystic degeneration. Askin tumors typically exhibit the EWS-FLI1 fusion mutation, although FUS-ERG chromosomal translocation has been described. Both rarity and variability of Askin tumors present a diagnostic challenge for clinicians. Collaborative effort amongst radiologists and pathologists is essential for diagnosis.

“…According to statistics, about 3/4 of cancer patients die of bone metastasis [2]. If the location and symptoms of the tumor are not obvious to the patient, metastatic bone tumors are easily misdiagnosed and even diagnosed and treated as primary bone tumors [3]. MAG-NETIC resonance whole-body diffusion imaging (MR whole-body diffusion imaging) makes use of the characteristic of limited movement of water molecules in tumor tissue cells so that bone metastases show high signal on DWI and are diagnosed [4].…”

Objective. To see if 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) imaging paired with MR diffusion imaging can help doctors diagnose bone metastases. Methods. From September 2020 to December 2021, a total of 30 individuals with probable bone metastases were recruited for the trial. With an average interval of four days, MAGNETIC resonance whole-body diffusion imaging (MR whole-body diffusion imaging) was performed on each of the 30 patients who had 18F-FDG PET/CT. The SUVmax values of the group with bone metastases were compared to those of the group without bone metastases. In this study, 18F-FDG PET/CT imaging, MR whole-body diffusion imaging, and their combination were examined. The researchers compared the results when 18F-FDG PET/CT imaging, whole-body MRI diffusion scans, and their combination indicated abnormal bone lesions. By comparing the diagnostic efficacy of 18F-FDG PET/CT imaging, MR whole-body diffusion imaging, and their combination, as well as accuracy, sensitivity, and specificity, the three techniques for diagnosing bone metastases will be evaluated for diagnostic usefulness. Results: the SUV max values of patients with bone metastases were significantly different from those of patients without bone metastases, as determined by 18F-FDG PET/CT imaging ( P < 0.05). Using 18F-FDG PET/CT imaging, MR whole-body diffusion imaging, and their combined detection of aberrant bone lesions in various areas, we found statistically significant differences. Conclusion. The use of 18F-FDG PET/CT imaging in conjunction with MR whole-body diffusion imaging in the diagnosis of bone metastases can be very helpful.
