Which description best defines a phlegmon in pancreatitis?

• A. Abscess
• B. Phlegmon
• C. Pseudocyst
• D. Hematoma

Answer: (B)

In pancreatitis, a phlegmon is an ill-defined inflammatory mass formed by edema and inflammatory cell infiltration spreading into the pancreas and surrounding peripancreatic tissues. It is not a fluid collection, so it lacks a true cavity or capsule. This distinguishes it from an abscess, which is a localized collection of pus and often has a fluid component and potential gas pockets. It also differs from a pseudocyst, which is a fluid-filled collection with a fibrous wall that develops weeks after the initial inflammation. A hematoma, on the other hand, is a blood collection from vessel rupture and can appear as a defined blood-filled area rather than an inflammatory, non-fluid mass.
