An 8-year-old girl with haemolysis, fever and a mass underneath the scapula. a Coronal STIR image shows a lesion with mixed signal intensity (open arrow) and multiple enlarged lymph nodes in the neck (solid arrow). b Axial T2-W image shows multiple cystic lesions with fluid-fluid levels (open arrow). Histopathology: stage IV embryonal RMS

Fig7: An 8-year-old girl with haemolysis, fever and a mass underneath the scapula. a Coronal STIR image shows a lesion with mixed signal intensity (open arrow) and multiple enlarged lymph nodes in the neck (solid arrow). b Axial T2-W image shows multiple cystic lesions with fluid-fluid levels (open arrow). Histopathology: stage IV embryonal RMS

Mentions: The imaging characteristics of RMS are relatively nonspecific. Like most soft-tissue tumours they have intermediate signal intensity on T1-W images (Fig. 6). On T2-W images they tend to be of intermediate-to-high signal intensity. If the tumour contains a high number of septa it may have a lobular shape. RMS in general show strong enhancement on postcontrast imaging (Fig. 6). In very rare instances the tumour may show a predominantly cystic appearance (Fig. 7). Dynamic series are useful in order to assess tumour vascularity, and to differentiate between postchemotherapy/surgery residual disease and fibrosis.Fig. 6
