[Radiological detection of the Medina worm (Dracunculus medinensis)]

Atypical linear or convoluted calcification in the subcutaneous tissues of patients from tropical areas in Africa and Asia may be caused by D. medinensis. The radiological appearances and differential diagnosis are described. Dead, calcified worms may occur in the soft tissues of the thorax, abdomen, pelvis or extremities and may cause complications due to a foreign body reaction, particularly when related to major joints.
