Sclerosing hemangioma of the lung showing strong FDG avidity on PET scan: Case report and review of the current literature

Sclerosing Hemangioma is a rare lung tumor with polymorphic histologic features that usually occurs in middle aged women. Based on many immunohistochemical and ultrastructural studies, it is most probably derived from undifferentiated respiratory epithelial cells. Symptoms are usually due to enlargement of the tumor and compression of the surrounding tissues. Occurrence of multiple lesions or metastasis is extremely rare although some authors consider sclerosing hemangioma as a potentially low grade malignancy tumor. It usually presents with low to moderate uptake on FDG PET imaging. We present a case of sclerosing hemangioma with strong FDG avidity on PET scan in a 41 year old lady with history of haemoptysis. A full review of the literature on this topic was performed. (C) 2015 The Authors. Published by Elsevier Ltd.
