Case presentations We report two cases of subpleural lipomas and describe their imaging characteristics on chest radiographs and computed tomography. We describe the cases of two Caucasian men aged 77 and 62 years old. Conclusions For non-invasive diagnostic investigation computed tomography enables the identification and quantification of these tumors due to their characteristic fat attenuation. Introduction Lipomas in general are encapsulated homogeneous mesenchymal slow growing tumors that arise in adipose tissue. Although they account for the most common benign soft tissue tumors in humans intra-thoracic lipomas are considered rare. Subpleural lipomas are parenchymal fat-containing lesions of the chest where they arise from the submesothelial layers of the pleura parie-talis and may extend into the subpleural pleural or extrapleural space 1 . Most patients remain asymptomatic and the lipoma is found incidentally on a chest radiograph or a computed tomography CT examination. Since only a few cases have been published in the recent literature we wanted to report two cases of sub-pleural lipomas with imaging findings from chest radiographs and CT examinations. Case presentations Case 1 A 77-year-old Caucasian man was referred to our hospital with a three-month history of recurring chest pain increasing in intensity over the last few days. He was a smoker and suffered from high blood pressure however he has refused antihypertensive medication since diagnosis. In 2006 he underwent
