Imaging features of thyroid tnvolvement by langerhans cell histiocytosis

Abstract

A 2-year-old male presented with fever, rash, right upper quadrant pain, and hyperbilirubinemia and was diagnosed with Langerhans cell histiocytosis (LCH). Periportal, hepatic, pulmonary, thymic, and thyroid involvement was noted on initial imaging. Thyroid gland involvement by LCH is rare. This case illustrates computed tomography, ultrasonography, and magnetic resonance imaging features of LCH of the thyroid.
