Abstract
Langerhans cell histiocytosis (LCH) is a haematological disorder, affecting single or multiple organs, characterized by abnormal proliferation of Langerhans cells in children. Accurate tumour delineation (number of lesions, organs involved) is crucial for staging/re-staging, and follow-up (response to therapy). Conventional imaging techniques (computed tomography (CT), magnetic resonance imaging (MRI)) have been employed for initial diagnosis, staging and assessment of response to therapy focusing on the healing effect therapeutic protocols have on the disease. In this case report, whole-body positron emission tomography/computed tomography (PET/CT) was shown either to provide information on the metabolic activity of histiocytes, or identify lesions otherwise asymptomatic. It is clear that PET/CT, combining anatomic and metabolic information, provides data for accurate staging, therapeutic protocol selection and assessment of response to therapy.
期刊介绍：
The Hellenic Journal of Nuclear Medicine published by the Hellenic Society of
Nuclear Medicine in Thessaloniki, aims to contribute to research, to education and
cover the scientific and professional interests of physicians, in the field of nuclear
medicine and in medicine in general. The journal may publish papers of nuclear
medicine and also papers that refer to related subjects as dosimetry, computer science,
targeting of gene expression, radioimmunoassay, radiation protection, biology, cell
trafficking, related historical brief reviews and other related subjects. Original papers
are preferred. The journal may after special agreement publish supplements covering
important subjects, dully reviewed and subscripted separately.
