Incidental Detection of a Giant Fecaloma on 18F-FDG PET/CT

We describe herein the incidental detection of a giant hypometabolic fecaloma on PET/CT with 18F-FDG during the initial staging of a patient with osteosarcoma using opioids for pain management.

Conclusions: The proposed nomogram is a reliable and robust tool for accurate prognostic prediction in patients with extremity soft tissue LMS. Introduction Soft tissue leiomyosarcoma (LMS) is an aggressive sarcoma, which originates from smooth muscle cells (1). Soft tissue LMS accounts for about 5–10% of all soft tissue sarcomas (2). It occurs in different sites, including the retroperitoneum, intraabdominal sites, and extremities (3). Extremity LMS comprised about 10–15% of extremity sarcomas, with a preference for the lower limb (4–6). Extremity LMS tends to have a better prognosis than uterine...

ConclusionGiant cell rich osteosarcoma is difficult to diagnose because its histology and radiologic feature mimic a benign giant cell tumor.

CONCLUSION: Surgical treatment of primary malignant tumors of the proximal fibula is problematic. In appropriate indications, Malawer type 1 resection should be the treatment of choice due to lower local recurrence rates and higher MSTS scores. PMID: 30885105 [PubMed - in process]

AbstractPaget ’s disease of bone (PDB) is a chronic and focal bone disorder, characterized by increased osteoclast-mediated bone resorption and a subsequent compensatory increase in bone formation, resulting in a disorganized mosaic of woven and lamellar bone at one or more affected skeletal sites. As a result, bone pain, noticeable deformities, arthritis at adjacent joints, and fractures can occur. In a small proportion of cases neoplastic degeneration in osteosarcoma, or, less frequently, giant cell tumor has been also described at PDB sites. While recent epidemiological evidences clearly indicate a dec rease in th...

Authors: Colangeli S, Parchi P, Andreani L, Beltrami G, Scoccianti G, Sacchetti F, Ceccoli M, Totti F, Campanacci DA, Capanna R Abstract Cryotherapy, also called Cryoablation (CA), is a technique that provides a local treatment to various pathological conditions. In Musculoskeletal tumours management, Cryoablation is well accepted and validated as a treatment in palliative cures for metastatic patients. Recently, CA has been proposed also as an alternative to radiofrequency ablation in osteoid osteoma and other benign tumour treatment with promising results. Cryotherapy with argon ice-balls as local adjuvant in ope...

Authors: Hardes J, Gosheger G, Budny T Abstract Bone sarcomas are extremely rare representing approximately 0.2% among all cancer types. Due to the rarity of these tumors both the patients and the physicians can overlook or misinterpret the first often unspecific symptoms of these tumors (pain, limping and swelling). Therefore, radiographic examination (X-ray and/or MRI) of the involved region in case of inexplicable symptoms is strongly recommended. The most common primary malignant bone tumor entity is osteosarcoma, followed by chondrosarcoma and Ewing sarcoma. Osteosarcomas and Ewing sarcomas occur predominantly...

Authors: Biazzo A, De Paolis M Abstract Osteosarcoma is a malignant bone tumor composed of mesenchymal cells producing osteoid and immature bone. Osteosarcoma is the most frequent primary malignant bone tumor, if we excluded myeloma, a haematologic disease. The incidence of osteosarcoma is 2-3/million/year, but is higher in adolescence, in which the annual incidence peaks at 8-11/million/year at 15-19 years of age. Local pain, followed by localized swelling and limitation of joint movement, are the typical signs and symptoms. Correct diagnosis can be achieved through a correct approach to the disease and the combin...

Conclusion Proximal femoral osteosarcoma is uncommon and rarely produces the typical clinical and imaging study findings. The atypical presentation often results in diagnostic errors and inappropriate treatments. Ill-defined osteolysis on standard radiographsshould prompt computed tomography or magnetic resonance imaging of the proximal femur. Treatment in a specialised centre is imperative. Level of evidence IV, retrospective study.
