title: Findings of magnetic resonance and colour-flow Doppler imaging of orbital embryonal rhabdomyosarcoma.
abstract: The authors describe a case of embryonal rhabdomyosarcoma of the orbit evaluated with magnetic resonance imaging (MRI) and colour-flow Doppler imaging. MRI demonstrated a markedly enhancing tumour with no discrete vessels. Colour-flow Doppler ultrasonography showed evidence of perfusion; however, discrete vascular channels were difficult to visualize, and no evidence of large vessels within the tumour was found at surgery. The differential diagnosis of this condition is discussed, as well as the potential role of colour-flow Doppler imaging in the assessment of orbital tumours, a role in which this method has not yet been widely applied.
