Lymphangioleiomyomatosis (LAM) is a diffuse proliferation of α-smooth muscle actin-positive cells associated with cystic destruction of the lung. LAM occurs almost exclusively in women, as a TSC manifestation or a sporadic disorder (TSC1/TSC2 somatic mutations). Biomarkers of whole-body tumor burden/activity and response to rapalogs or other therapies remain needed in TSC/LAM. It was reported that TSC2-deficient cells enhance phosphatidylcholine synthesis via the Kennedy pathway. 11C-Choline can reflect the metabolic process of choline in vivo by intravenous injection.
