The Modified Balthazar Score is a widely used clinical tool designed to assess the severity of acute pancreatitis based on computed tomography (CT) imaging. It assigns points to specific findings on the CT scan that reflect the degree of inflammation, fluid accumulation, and pancreatic tissue damage. This scoring system helps predict the risk of complications, such as infection, necrosis, or organ failure, and provides guidance for treatment and monitoring strategies.
The score is calculated by evaluating two main components: the extent of visible changes in the pancreas and surrounding tissues on a contrast-enhanced CT scan, and the presence and degree of pancreatic necrosis (evaluated on non-contrast CT). The total score ranges from 0 to 10, with higher scores indicating more severe disease and a greater risk of mortality.
Acute pancreatitis is a sudden inflammation of the pancreas, a gland located behind the stomach that plays an essential role in digestion and blood sugar regulation. When the pancreas becomes inflamed, it can release digestive enzymes prematurely, causing damage to its own tissue and triggering a range of symptoms, from mild discomfort to life-threatening complications.
Symptoms of acute pancreatitis commonly include severe upper abdominal pain that may radiate to the back, nausea, vomiting, fever, and a rapid pulse. In mild cases, the condition resolves with supportive care, such as hydration and pain management. However, in more severe cases, inflammation can spread beyond the pancreas, causing fluid buildup, infection, and systemic complications that may require intensive medical intervention.
The causes of acute pancreatitis vary and can include gallstones (which block the pancreatic duct), excessive alcohol consumption, high triglyceride levels, certain medications, and abdominal trauma. Diagnosing and monitoring the severity of the condition early is critical to prevent complications and improve outcomes.
CT scans are one of the most valuable imaging tools in the evaluation of acute pancreatitis. A contrast-enhanced CT scan provides detailed cross-sectional images of the pancreas and surrounding tissues, allowing doctors to assess the extent of inflammation, identify fluid collections, detect necrosis (areas where pancreatic tissue has died), and rule out other abdominal conditions that may present similarly.
In the early stages of acute pancreatitis, CT imaging can help confirm the diagnosis and identify any complications that may require immediate intervention. Over the course of the illness, repeated CT scans may be used to monitor disease progression or improvement.
The Modified Balthazar Score is based on findings from these CT scans and is divided into two parts:
By combining these two scores, physicians can obtain a total severity score that correlates with the likelihood of complications and mortality. This information is crucial in determining the level of care a patient needs, whether it be hospital admission, intensive care, or surgical intervention.
The Modified Balthazar Score works by evaluating two key features observed in CT scans of patients with acute pancreatitis: visible pancreatic changes and the extent of tissue necrosis. Each of these components is scored individually and then combined to produce a total score ranging from 0 to 10. The higher the score, the more severe the pancreatitis and the greater the risk of complications or death.
This scoring system allows clinicians to objectively assess the severity of the disease and make informed decisions about patient management, including hospitalization, monitoring, and potential need for intensive care.
The Modified Balthazar Score is made up of two main parts:
Each component contributes a number of points to the overall score, and the combined result helps estimate mortality risk and clinical severity.
This component evaluates how the pancreas and surrounding tissues appear on a contrast-enhanced CT scan. It reflects the presence and extent of inflammation, as well as the presence of fluid collections or gas. The options are scored from 0 to 4 points:
This component measures the extent of pancreatic tissue death (necrosis) seen on a non-contrast CT scan. The more tissue that is affected, the higher the score. This part is scored from 0 to 6 points:
The total score is the sum of the scan score and the necrosis score. Once calculated, the score can be interpreted to estimate the severity and expected mortality:

Once you’ve used the Modified Balthazar Score Calculator, you’ll receive two important pieces of information: your total score and the estimated mortality risk. Understanding what these results mean can help guide discussions with your healthcare provider and give insight into the severity of acute pancreatitis.
Your final score will be a number between 0 and 10, based on the combined points from the pancreatic condition and necrosis level selected. This score reflects the overall severity of the pancreatitis observed on CT scans.
In addition to the score, the calculator provides an estimated percentage for mortality risk. This number offers a general idea of how serious the condition may be, based on clinical data. Here’s how the mortality risk is estimated:
The Modified Balthazar Score offers valuable insight into the severity of acute pancreatitis by translating CT scan findings into a clear numerical scale. Each score range corresponds to a different clinical outlook, helping guide decisions on patient care, monitoring, and treatment intensity.
A score between 0 and 3 is considered low and typically indicates a mild case of acute pancreatitis. This means the pancreas shows little to no inflammation, no significant fluid collections, and no signs of tissue necrosis. These patients usually recover with supportive care such as fluids, pain management, and rest.
In most cases, patients with a low score have:
However, even with a low score, clinical symptoms and other lab findings should always be considered by a healthcare provider.
A score between 4 and 6 suggests moderate pancreatitis. This range may indicate increased pancreatic inflammation, early fluid collection, and partial necrosis of the pancreatic tissue. These cases require closer observation, as the risk of complications is higher than in mild cases.
Patients with intermediate scores may experience:
Careful medical management is important to prevent deterioration into a more severe state.
A score between 7 and 10 is classified as severe pancreatitis. This score typically reflects the presence of multiple peripancreatic fluid collections, gas (suggesting infection), and significant or extensive pancreatic necrosis.
Patients in this category are at a high risk for:
These patients usually require urgent, intensive medical care and may need drainage procedures, antibiotics, or other invasive treatments.
While the Modified Balthazar Score is a helpful tool in evaluating the severity of acute pancreatitis, it is not a standalone diagnostic method. It should be used as part of a broader clinical assessment that includes physical examination, medical history, blood tests, and other imaging results. There are several important limitations and considerations to keep in mind when interpreting the score.
In short, the Modified Balthazar Score is just one piece of the puzzle. It is useful, but should never be used in isolation to make treatment decisions.
If you or someone you know is experiencing symptoms such as severe abdominal pain, vomiting, fever, or signs of dehydration, it’s important to seek medical attention immediately. Acute pancreatitis can progress quickly, and early diagnosis is essential for preventing complications.
Always consult a healthcare professional if:
Only a qualified medical provider can determine the appropriate level of care, which may include hospitalization, medications, or further imaging and testing.
The Modified Balthazar Score should always be interpreted in the context of the full clinical picture. A patient’s symptoms, physical exam, lab results (such as elevated lipase or amylase levels), and response to treatment are all essential factors in diagnosing and managing acute pancreatitis.
For example, a patient with a moderate score but stable vital signs and improving symptoms may not require aggressive treatment, while another patient with a low score but signs of systemic inflammation may need close monitoring.
