| Description | The role of 18F-FDG PET/CT imaging in patient with malignant PEComa treated with mTOR inhibitor Lu Sun,1 Xiaorong Sun,2 Yuhui Li,3 Ligang Xing4 1School of Medicine and Life Sciences, University of Jinan-Shandong Academy of Medical Sciences, 2PET/CT Center, Department of Radiology, 3Department of Pathology, 4Department of Radiation Oncology, Shandong Cancer Hospital and Institute, Jinan, Shandong, People's Republic of China Malignant perivascular epithelioid cell tumor (malignant PEComa) is a rare disease for which the diagnostic criteria and treatment options have not been established. Since PEComa is associated with upregulation of mammalian target of rapamycin (mTOR) pathway which controls Glut-1 (glucose transporter) function, increased 18F-fluorodeoxyglucose (18F-FDG) uptake may indicate the over activation of mTOR pathway and may guide selectively inhibiting mTOR pathway treatment. We report a malignant PEComa patient who presented for 18F-FDG positron emission tomography/computed tomography (PET/CT) restaging. The tumor had shown significant avidity on PET/CT as well as an evident response to sirolimus (rapamycin, Rapamuneā¢) that supports the utility of mTOR inhibitors as an effective treatment for malignant PEComa. Therefore, 18F-FDG PET/CT is helpful in restaging and guiding treatment for malignant PEComa with mTOR inhibitors.
