Abstract
Erdheim-Chester Disease (ECD) is a rare systemic histiocytic disorder characterized by symmetrical skeletal involvement and variable visceral manifestations. Tc-99m MDP bone scintigraphy, CT, MRI, and FDG PET-CT are essential for diagnosis and disease mapping. ECD's course depends on extraosseous involvement, with potential complications including heart and renal failure. We present the case of ECD with bilateral leg pain and orbital involvement. Imaging revealed mixed sclerotic and lytic skeletal lesions, cerebellar lesions, intraorbital soft tissue masses, mediastinal and retroperitoneal infiltration.
期刊介绍:
Primarily being a medical journal, JPMA publishes scholarly research focusing on the various fields in the areas of health and medical education. It publishes original research describing recent advances in health particularly clinical studies, clinical trials, assessments of pathogens of diagnostic importance, medical genetics and epidemiological studies. Review articles highlighting importance of various issues in the domain of public health, drug research and medical education are also accepted. As a leading journal of South Asia, JPMA remains cognizant of the recent advances in the rapidly growing fields of biomedical sciences, it invites and encourages scholars to write short reviews and invited editorials on the emerging issues. We particularly aim to promote health standards of developing countries by encouraging manuscript submissions on issues affecting the public health and health delivery services.
