Abstract:
Gallbladder perforation is one of the most serious complications of cholecystitis and is rarely seen in 2-11% of cases. Pericholecystic abscesses secondary to gallbladder perforation are rare. Rapid diagnosis is important because of high morbidity and mortalityrates. A subcapsular abscess secondary to gallbladder microperforation is presented on 18F-fluorodeoxyglucose positron emission tomography/computed tomography performed for restaging in a patient with maxillary sinus cancer.
Insights
Gallbladder perforation, a rare but serious complication of cholecystitis, can lead to abscesses. This case highlights diagnosing a subcapsular abscess using 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in a cancer patient.
Area of Science:
- Gastroenterology
- Radiology
- Oncology
Background:
- Gallbladder perforation is a severe complication of cholecystitis, occurring in 2-11% of cases.
- Pericholecystic abscesses resulting from gallbladder perforation are infrequent.
- Prompt diagnosis of gallbladder perforation is crucial due to high morbidity and mortality.
Purpose of the Study:
- To present a rare case of a subcapsular abscess secondary to gallbladder microperforation.
- To illustrate the utility of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in diagnosing such abscesses.
Main Methods:
- A patient with maxillary sinus cancer underwent FDG-PET/CT for restaging.
- The imaging incidentally revealed a subcapsular abscess.
- The findings were correlated with clinical presentation.
Main Results:
- FDG-PET/CT successfully identified a subcapsular abscess attributed to gallbladder microperforation.
- The imaging provided crucial diagnostic information in a patient undergoing cancer restaging.
Conclusions:
- Subcapsular abscesses secondary to gallbladder microperforation are rare but can be detected by FDG-PET/CT.
- FDG-PET/CT can play a role in the diagnosis of unexpected gallbladder complications, even during oncologic imaging.
