Mesenteric lymphadenitis depicted by indium 111-labeled white blood cell imaging.
An acutely ill child with abdominal pain and concomitant pharyngitis often presents a diagnostic challenge. This report describes how indium 111-labeled white blood cell imaging helped to clarify the confusing case of a 4-year-old boy with fever, pharyngitis, and abdominal pain. The triad of abnormal white cell localization in the nasopharynx, cervical lymph nodes, and right lower abdominal quadrant supported the diagnosis of a systemic infection rather than appendicitis, abscess, or another surgical condition. Mesenteric lymphadenitis associated with systemic infection should be included in the differential diagnosis of abdominal pain in a child with this clinical presentation.
