ABSTRACT
Magnetic resonance is a noninvasive, nonionizing modality used in the detection and evaluation of marrow lesions, as well as surgical planning and treatment follow-up. Since the distribution of red and yellow marrow occurs in a predictable sequence according to age, understanding this sequence is essential in establishing an accurate and timely diagnosis. This article provides an overview of the normal appearance of bone marrow in healthy children as well as focal and diffuse marrow abnormalities. Imaging pitfalls unique to children and solutions to use in difficult cases will be described.

A 73-year-old man presented with a red papule on the posterior aspect of his neck (Figure 1). The growth had first been noted approximately 1 month before his visit. The patient complained of irritation from his collar but had no other symptoms. He had hypertension controlled by medication and denied recent weight loss, malaise, or swollen glands. Examination of the lesion revealed a firm, bright red papule 4 mm in diameter on a slightly indurated flesh-color base. (SKINmed. 2019;17:65-66).
