Why the study?
Mediastinal epithelioid hemangioendothelioma is very exceptional with no standardized treatment, and only few reports utilizing FDG PET/CT are available.
Does FDG PET/CT improve staging compared to CT in a patient with mediastinal epithelioid hemangioendothelioma?
Does FDG PET/CT improve staging compared to CT in a patient with mediastinal epithelioid hemangioendothelioma?
FDG PET/CT demonstrated higher sensitivity than CT for staging a rare case of mediastinal epithelioid hemangioendothelioma.
FDG-avid mediastinal EHE may remain untreated and stable; leaves open whether PET/CT findings should guide therapy in this rare tumor.
Epithelioid hemangioendothelioma is a rare low- to intermediate-grade malignant vascular neoplasm with a variable clinical course and currently no standardized treatment. We present a case of a 65-year-old woman diagnosed as having mediastinal epithelioid hemangioendothelioma, a location which is very exceptional. FDG PET/CT was more sensitive than CT for staging, revealing intense FDG uptake in the primary tumor and in the metastatic disease. Despite high FDG uptake, the disease was stable with no further specific treatment. Only few reports utilizing FDG PET/CT are available; review of the literature on this subject is included.
