Acute Adenoviral Gastroenteritis Complicated by Interstitial Edematous Pancreatitis in an Adult Patient: A Rare Clinical Case With a Multidisciplinary Approach

Abstract

Adenovirus F (type 40/41) is one of the most significant viral etiological agents of acute gastroenteritis in young children. This is a significant and growing cause of pediatric gastroenteritis worldwide, particularly in children under the age of five. However, in rare cases, it may also lead to clinically significant illness in adults. The clinical case we present describes the course of acute adenoviral gastroenteritis complicated with acute pancreatitis and a pronounced intoxication syndrome in a 24-year-old woman from Ukraine.

Keywords: acute intestinal infection; adenovirus f; adenovirus infection; diarrhea; gastroenteritis; pancreatitis; vomiting.

Figure 1. Ultrasound examination of the pancreas (the pancreatic head)

The pancreatic head exhibits increased echogenicity with blurred contours, indicative of tissue edema. The structure measures 36.8 mm in transverse section (blue dashed line; Dist A), suggesting volume increase due to the inflammatory process. Surrounding tissues show diffuse decreased echogenicity, typical of edema, with hypoechoic areas that may correspond to inflammatory infiltrates. No distinct signs of necrosis or pseudocysts are present.

Figure 2. Ultrasound examination of the pancreas (the body of the pancreas)

The body of the pancreas is visualized as a homogeneous structure with medium echogenicity and well-defined, smooth contours. The structure measures 25.4 mm in transverse section (blue dashed line; Dist A), which is consistent with the normal range for this anatomical region. The surrounding tissues exhibit normal echogenicity without signs of diffuse changes or focal lesions. No visible pathological inclusions, such as cystic or solid masses, are present.
