What are the imaging characteristics of Ewing sarcoma family of tumours in adults on MRI and CT?
In adults with Ewing sarcoma family of tumours, extraskeletal involvement occurs in 18% of cases, and MRI is superior to CT for delineating bone marrow and soft tissue involvement.
Answers are grounded in this paper and cite their sources.
MRI may aid staging in adult Ewing sarcoma; leaves open prospective validation before changing practice.
This review describes the imaging characteristics of Ewing sarcoma family of tumours (ESFT) exclusively in an adult population.The magnetic resonance imaging (MRI) and computed tomography (CT) appearances in 50 adult patients with ESFT is described.The imaging characteristics in this largest case series of adult ESFT reported so far, were similar to those reported in the paediatric ESFT.Our incidence of extra skeletal ESFT of 18% is the highest reported so far in the adult population and is higher than the reported incidence of (8%) in the paediatric and adolescent population.MRI was found to be superior to CT scan in identifying tumour involvement of the bone marrow and in delineating the soft tissue involvement due to its multi-planar imaging capability.

Chatterjee et al. (2017) conducted an observational in Ewing sarcoma family of tumours (ESFT) (n=50). CT and MRI imaging was evaluated on Incidence of extraskeletal tumors and imaging characteristics. In 50 adult patients with Ewing sarcoma family of tumors, the incidence of extraskeletal tumors was 18%, and MRI was superior to CT for identifying bone marrow and soft tissue involvement.
