Focal myositis is a rare idiopathic form of inflammatory myositis involving a single muscle . The presentation is often as a soft tissue pseudotumour . Magnetic resonance imaging (MRI ) is a useful noninvasive imaging modality to demonstrate focal nature of the lesion . We describe three patients presenting as pseudotumour of the lower leg .
