We present a right ACC that was found on a routine health checkup and was confirmed by simultaneous measurements of late-afternoon serum cortisol and ACTH levels in a 65-year-old woman. Preoperative F-18 FDG PET/CT revealed intense F-18 FDG uptake in the right adrenal region with tumor invasion in the IVC. This PET result was also confirmed by subsequent abdominal MRI. The patient then had a right adrenalectomy with IVC thrombectomy. Pathologic analysis of the right adrenal tumor and the thrombus from the IVC was consistent with ACC. ? 2007 Lippincott Williams & Wilkins, Inc.[SDGs]SDG3corticotropin; fluorodeoxyglucose f 18; hydrocortisone; adrenal cortex; adrenal cortex carcinoma; adrenalectomy; adult; article; cancer invasion; case report; computer assisted emission tomography; corticotropin blood level; drug uptake; female; human; hydrocortisone blood level; inferior cava vein; measurement; nuclear magnetic resonance imaging; pathology; thrombectomy; tumor thrombus; Adrenal Cortex Neoplasms; Adrenocortical Carcinoma; Female; Fluorodeoxyglucose F18; Humans; Middle Aged; Neoplasm Invasiveness; Positron-Emission Tomography; Tomography, X-Ray Computed; Vena Cava, InferiorF-18 FDG PET/CT illustrating tumor invasion in the IVC from adrenocortical carcinomajournal article10.1097/RLU.0b013e318156bf64180754332-s2.0-37349072815
