Abstract

This case report discusses a 2-year-old child presenting with pericardial inflammatory myofibroblastic tumor (IMT) involving the inferior vena cava (IVC) causing hepatomegaly, which manifested as incidental upper abdominal distension without accompanying abdominal pain, nausea, or vomiting. Preoperative imaging revealed a soft tissue mass within the pericardium and pericardial effusion, causing deformation of the left atrium, and involving the IVC causing hepatomegaly. Subsequently, she underwent a mediastinal mass excisional biopsy by thoracotomy, which uncovered a smooth, resilient mass in the pericardium closely associated with the diaphragm. The tumor exhibited a fish-flesh appearance upon sectioning, with moderate pale red bloody fluid within the pericardium. The final pathology revealed an IMT. This case recapitulates the pathological classification, imaging findings, and differential diagnosis of the rare pericardial IMT
