Jafari Reza

Purpose: Langerhans cell histiocytosis (LCH) is a rare disorder that affects the pediatric population. However, LCH presentation as a bony lytic and cystic lesion with fluid-fluid levels (FFLs) is unusual. Observation: We describe imaging and pathologic section features of A 13-year-old boy who presented with several weeks history of a right eyebrow mass with persistent lid swelling and blepharoptosis caused by orbital LCH of the frontal bone with bony lytic lesion and multiple fluidfluid levels. Conclusion and importance: despite some cases of calvarial or orbital LCH previously reported and even a few cases of LCH had fluid-fluid levels, however, our case is first reported orbital LCH with multiple fluid-fluid levels. Keywords: Orbital, Langerhans Cell Histiocytosis (LCH), Fluid-fluid levels.
