ABSTRACT
Magnetic resonance imaging (MRI) has proven its relevance in the imaging of adult ungual diseases but remains limited in children.1 Imaging is rarely performed and consists mainly of conventional radiographs and occasionally, ultrasonography. In our institution, we conducted MRI for 50 children, with ages ranging from 6 to 15 years, from 1996 to 2015. Examination consisted of 25 ngers among 9 thumbs and 25 toes; 18 were great toes. Two etiologies dominated the indications: traumatic lesions and exostosis. The remaining indications consisted of tumor, infectious, and congenital abnormalities. We will rst discuss the specic technical aspect of MRI in children, the normal nail apparatus anatomy, and our two primary indications. The other indications will be briey reviewed at the end of this chapter.
