PET-CT case of the month (04/09): Adenocarcinoma of Unknown Origin
A 71 yrs old male was admitted with increasing shortness of breath and was
found to have a large left side pleural effusion. Thoracentesis revealed an
exudate with many RBCs and the cytology was negative. CT scan showed a
large left pleural effusion, circumferential pleural thickening, and a posterior
mediastinal mass. EUS guided FNA of the mediastinal mass revealed
adenocarcinoma.

Whole body PET-CT showed: FDG avid left lung pleural thickening,
hypermetabolic right paratracheal lymphadenopathy (SUV 5.1), and focal
hypermetabolism in the thickened lower esophagus (SUV 15.7). EGD revealed
esophageal adenocarcinoma. Incidentally seen on PET-CT is an intensely FDG
avid (SUV 36.7) fluid density mass in the left scrotum, from inguinal herniation of
the urinary bladder.
