Occult cholecystitis presenting as PUO demonstrated on Gallium

摘要

Gallium-67 scintigraphy is commonly performed to investigate Pyrexia of Unknown Origin (PUO) due to its affinity for infection or inflammation. The dissemination of hybrid SPECT CT imaging allows improved identification and localisation of causes of PUO. A 74 year old male was referred for investigation of pyrexia of unknown origin. Gallium SPECT CT was performed and demonstrated increased Gallium uptake in the gallbladder wall with features of cholelithiasis and collection on the corresponding CT images. At operation the gallbladder revealed areas of chronic cholecystitis and xanthogranulomatous inflammation.
