18F-FDG PET/CT of Hepatosplenic Actinomycosis After Laparoscopic Cystojejunostomy for Pancreatic Pseudocyst

Clin Nucl Med. 2021 Apr 1;46(4):e224-e225. doi: 10.1097/RLU.0000000000003260.

Abstract

We report the 18F-FDG PET/CT appearance of abdominal actinomycosis in a 48-year-old immunocompetent woman with a history of laparoscopic cystojejunostomy for pancreatic pseudocyst previously. 18F-FDG PET/CT demonstrated multiple hypermetabolism in the liver, spleen, cystojejunostomy anastomosis, greater omentum, and umbilical region. Actinomycosis was verified by biopsy. Hepatosplenic actinomycosis secondary to cystojejunostomy is extremely rare and easily to be misdiagnosed. PET/CT is helpful for auxiliary diagnosis, guiding biopsy, and exploring the extent of the disease.
