“…However, 18 F-FDG PET/CT can show a hypermetabolic mediastinal mass-like lesion in other malignancies such as thymic carcinoma, lymphoma, and some benign lesions such as sarcoidosis; thus, it may be challenging to discriminate MFH from other mediastinal neoplasms by the pattern of 18 F-FDG uptake [12][13][14]. According to several reports of MFH developing in the kidney, maxillary sinus, brain and the lung, all MFHs showed high 18 F-FDG uptake with a central metabolic defect, which was similar with the present case [6][7][8][9]. 18 F-FDG-avid lesions in the renal and pulmonary MFH were detected on PET/CT, and their SUVs max were 6.8 and 12.1, respectively [6,7].…”

“…18 F-FDG-avid lesions in the renal and pulmonary MFH were detected on PET/CT, and their SUVs max were 6.8 and 12.1, respectively [6,7]. In other cases with MFH in the maxillary sinus and the brain, high 18 F-FDG uptake was demonstrated (SUV max 016.9 and 4.0, respectively) [8,9]. MFH generally manifests as a bulky, multilobular mass with progressive enlargement over several months.…”

“…However, many other sites, such as the thorax (thymus, mediastinum, chest wall, lung, diaphragm, heart and great vessel), maxillary sinus, bladder, kidney, ovary, anal canal, and the brain, were reported [5][6][7][8][9]. MFH originating in the mediastinum has rarely been reported.…”

Malignant fibrous histiocytoma (MFH) is the most common soft tissue tumor which often occurs in the extremities and the retroperitoneum. Primary mediastinal MFH is rare; thus, findings on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) of mediastinal MFH have not been reported yet. We report herein the case of a 64-year-old man who was presented with a superior mediastinal mass. The mass showed intense 18 F-FDG uptake with central metabolic defect on PET/CT. The maximum standardized uptake value was 17.4. After tumor removal via median sternotomy, an MFH of the storiform-pleomorphic type was diagnosed on histopathologic examination. We present the first report of 18 F-FDG PET/CT imaging of MFH in the superior mediastinum.

“…18 F-FDG PET/CT has proven to be useful in the staging of MFH and identification of metastatic disease in unusual locations 12 – 14 and the use of 18 F-FDG PET/CT for staging of aggressive sarcomas including MFH is recommended in the joint RCR and RCP evidence-based guidelines for the use of PET/CT in the United Kingdom (2016); 15 however, to our knowledge, the use of 18 F-FDG PET/CT in the staging of splenic PSCS has not been previously described. Owing to the highly aggressive nature of this splenic malignancy, including two recent reports of spontaneous tumour rupture 6 , 10 timely imaging with PET/CT is crucial for implementation of treatment.…”

Pleomorphic spindle cell sarcoma (PSCS) (formerly known as malignant fibrous histiocytoma, MFH) of the spleen, mimics an atypical haemangioma on^99mTc-RBC, CT and Ultrasound: staging with¹⁸F-FDG PET/CT

A 63-year-old male was found to have a 7.5-cm splenic mass that had imaging appearances of an atypical haemangioma on CT, ultrasound and a 99mTc-RBC scan, and he was followed conservatively with serial ultrasounds. Sixteen months later, however, the splenic lesion grew and he developed numerous new liver masses which were biopsy confirmed to be a pleomorphic spindle cell sarcoma (PSCS), formerly known as malignant fibrous histiocytoma (MFH). A staging 18F-FDG PET/CT was performed and showed innumerable, mostly necrotic hepatic and splenic masses. The patient passed away a few days after the PET/CT, before a treatment program could be implemented. The use of 18F-FDG PET/CT in the staging of splenic PSCS has not been previously described. We present the 99mTc-RBC and 18F-FDG PET/CT image characteristics of a patient with splenic PSCS.

This article briefly reviews malignant bone tumors, diffuse marrow infiltrating diseases, and other benign bone diseases with fluorodeoxyglucose (FDG) uptake on positron emission tomography/computed tomography (PET/CT) that should be differentiated from malignant tumors. Clinical use of FDG PET/CT in (1) primary malignant bone tumors including osteosarcoma, malignant fibrous histiocytoma, and primary bone lymphoma, (2) hematopoietic tumors with bone marrow involvement, such as plasmacytoma, multiple myeloma, lymphoma and leukemia, and (3) benign tumors and tumor-like lesions including hemangioma, neurogenic tumor, fibrous dysplasia, and nodular fasciitis are presented, with an emphasis on various imaging findings on FDG PET/CT. Benign tumors and tumor-like conditions are often incidentally detected on FDG PET/CT in serial follow-up studies of cancer patients and should be differentiated from metastasis.
