Abnormal FDG Uptake in the Pericardial Adipose Tissue Mimicking Malignancy
نویسندگان
چکیده
Focal mediastinal F-18 FDG uptake may be from potential adenopathy requiring biopsy confirmation or benign active brown adipose tissue to be left untouched. Knowledge of this potential pitfall and precise localization with fusion PET/CT are important in preventing misinterpretation as malignancy. Our case report is important in the aspect that CT was not able to confirm the uptake as benign finding, which led to invasive biopsy and biopsy confirmed it to be a benign brown adipose tissue.

Nuclear Medicine: Asymmetric 18F-FDG Uptake in the Infradiaphragmatic Brown Adipose Tissue (BAT) Mimicking Adrenal Metastasis: A Relatively Rare Site of Brown Fat and a Potential Source for False Positive FDG-PET Study
FDG uptake in the metabolically active brown adipose tissue (BAT) is a source of significant concern while interpreting FDG-PET studies. It is also of great interest due to its potential implications for obesity research. In this communication, we describe hitherto unreported asymmetric BAT uptake in the abdomen, persisting after diazepam intervention in the repeat PET study on a separate day. ...

A 24-year-old woman with paroxysmal episodes of hypertension and palpitation was found to have paraganglioma located at the left renal hilum (6.3 cm in size) as detected by MRI scan, where radioactivity was exclusively accumulated by I-MIBG scintigraphy. She had markedly increased plasma and urinary noradrenaline levels. F-FDG-PET scan demonstrated an increased uptake not only in the tumor (Pic...

Pyrexia of unknown origin (PUO) is a common problem in day-to-day practice. FDG PET CT is an established investigation that aids in identifying the cause of PUO. Due to its high sensitivity PET detects an occult hypermetabolic focus in the body where CT helps in anatomical localization, vascularity, enhancement characteristics of the lesion detected on PET. It helps to differentiate benign vers...
متن کاملPrimary Benign Intraosseous Meningioma on 18F-FDG PET/CT Mimicking Malignancy
We present a case of primary benign intraosseous meningioma in the sphenoid bone mimicking malignancy. A 44-year-old female patient who had a protruding right eye and headache came to our hospital. MRI showed a large, destructive, heterogeneously well-enhancing soft tissue mass in the right sphenoid bone suggesting malignancy. (18)F-FDG PET/CT showed a hypermetabolic mass in the same site with ...

OBJECTIVE To measure FDG uptake in visceral (VAT) and subcutaneous (SAT) adipose tissue of metabolically healthy obese (MHO) and metabolically abnormal obese (MAO) compared to metabolically healthy lean (MHL) subjects. Given that MHO has increased metabolic risk, it was hypothesized that MHO and MAO display similar VAT FDG uptake. METHODS The 18F-FDG-PET/CT studies of 141 adults (n = 60 MHL, ...
