Ewing's Sarcoma Omental Odyssey: Unraveling Rare Metastasis and Unforeseen Treatment Outcome on FDG PET/CT: Case Report with Review of Literature
Funding None.
Abstract
Ewing's sarcoma is an uncommon and highly metastatic form of sarcoma affecting children and young adults, occurring in approximately 1 in 1.5 million individuals, with a predominance in males. We present an exceptionally unique case highlighting Ewing's sarcoma metastasis to the peritoneum and omentum, identified through an 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan and its unforeseen treatment response. In contrast to previously published literature concerning primary peritoneal primitive neuroectodermal tumors, this exceedingly notable instance illuminates the occurrence of metastatic Ewing's sarcoma within the peritoneum, as opposed to originating as a primary tumor within the peritoneum, revealing diagnostic intricacies. This case accentuates several pivotal learning points that enhance our understanding of Ewing's sarcoma. Also, the noteworthy high sensitivity and specificity of 18F-FDG PET/CT allow for early detection of recurrence and treatment response, substantially improving prognosis in Ewing's sarcoma patients, aiding in timely therapeutic interventions and optimizing patient outcomes.
