Computed tomography (CT) scans utilize X-ray technology and computer processing to create detailed cross-sectional images of the body. This imaging technique can help assess the severity of acute cholecystitis, detect complications such as gallbladder perforation, and evaluate surrounding structures.
MRI
Magnetic resonance imaging (MRI) uses a powerful magnetic field and radio waves to produce detailed images of the body’s organs and tissues. MRI is particularly useful in cases where ultrasound findings are inconclusive or additional information is needed. It can provide a more comprehensive assessment of the inflamed gallbladder, identify associated complications, and evaluate adjacent organs.
Nuclear Medicine Scans
Nuclear medicine scans involve the injection of a small amount of radioactive material into the body. These scans assess the function and structure of organs, allowing for the evaluation of gallbladder inflammation. Two common nuclear medicine scans used in the evaluation of acute cholecystitis are hepatobiliary iminodiacetic acid (HIDA) scans and technetium-99m (Tc-99m) disofenin hepatobiliary scintigraphy. These scans provide insights into gallbladder function, bile flow, and potential anatomical abnormalities.
While these alternative imaging modalities can provide valuable information, ultrasound remains the primary imaging modality for diagnosing acute cholecystitis due to its accessibility, cost-effectiveness, and ability to visualize real-time images. The use of alternative imaging techniques is determined on a case-by-case basis, taking into account the patient’s specific condition and the clinician’s assessment.

Ignoring symptoms or delaying medical intervention can result in severe consequences, including:
- Gallbladder Rupture: If acute cholecystitis is left untreated, the inflamed gallbladder can eventually rupture, leading to a life-threatening condition. A ruptured gallbladder can cause infection in the abdominal cavity, known as peritonitis, requiring immediate surgical intervention.
- Infection: The inflammation in the gallbladder can facilitate the growth of bacteria, leading to the development of an infection. Furthermore, if the gallbladder ruptures, the infection can spread throughout the abdominal cavity, causing widespread infection and sepsis.
- Biliary Obstruction: Acute cholecystitis can cause the gallbladder to become enlarged and filled with inflammatory fluid, leading to biliary obstruction. This obstruction can affect the normal flow of bile, causing pain, jaundice, and a potential backup of bile in the liver.
Gallbladder Rupture
Gallbladder rupture is one of the most severe complications associated with untreated acute cholecystitis. It results from the continuous inflammation and pressure build-up in the gallbladder. As the gallbladder wall weakens, it may eventually burst, releasing bile and inflammatory fluid into the abdominal cavity. This can lead to a dangerous condition known as peritonitis, characterized by severe abdominal pain, fever, nausea, and a potential risk of sepsis.
Infection
The presence of inflammation in the gallbladder can create an ideal environment for bacterial growth. If the infection is not treated promptly, it can rapidly spread, leading to systemic infection and sepsis. This life-threatening condition requires immediate medical attention and often necessitates surgical intervention to remove the infected gallbladder and address any complications that may have arisen.
Biliary Obstruction
During acute cholecystitis, the gallbladder can become enlarged and filled with inflammatory fluid. This can exert pressure on the bile ducts, leading to biliary obstruction. The obstruction hampers the flow of bile, causing pain, jaundice, and potential complications in the liver. It is crucial to address the underlying cause of the inflammation to prevent further damage to the gallbladder and biliary system.
| Complications of Untreated Acute Cholecystitis | Description |
|---|---|
| Gallbladder Rupture | A life-threatening condition that occurs when the inflamed gallbladder bursts, releasing bile and inflammatory fluid into the abdominal cavity. |
| Infection | The inflammation in the gallbladder can create an environment for bacterial growth, leading to the development of an infection that can become systemic and cause sepsis. |
| Biliary Obstruction | Enlargement of the gallbladder and inflammation can exert pressure on the bile ducts, leading to obstruction and hindering the flow of bile. |
