Hot Quadrate Sign Under Focus of F18-FDG PET-CT: An Incidental Finding.
"Hot quadrate lobe sign" refers to visualization of caudate lobe of liver due to excess accumulation of radiotracer secondary to superior vena cava obstruction. Collateral channels are formed between thoracic and mediastinal vessels; internal mammary through the paraumbilical vessels which drain blood to the left portal vein and into the caudate lobe of liver. It was first described on Tc99-m sulfur colloid scan. We present a case with superior vena cava obstruction presenting as hot quadrate lobe sign on F18-FDG PET-CT.
期刊介绍:
Primarily being a medical journal, JPMA publishes scholarly research focusing on the various fields in the areas of health and medical education. It publishes original research describing recent advances in health particularly clinical studies, clinical trials, assessments of pathogens of diagnostic importance, medical genetics and epidemiological studies. Review articles highlighting importance of various issues in the domain of public health, drug research and medical education are also accepted. As a leading journal of South Asia, JPMA remains cognizant of the recent advances in the rapidly growing fields of biomedical sciences, it invites and encourages scholars to write short reviews and invited editorials on the emerging issues. We particularly aim to promote health standards of developing countries by encouraging manuscript submissions on issues affecting the public health and health delivery services.
