Complete resection of giant pericardial synovial sarcoma in a 7-year-old
boy: a case report
Abstract
Background: Synovial sarcoma is a rare soft-tissue malignant tumor most
commonly occurring in the extremities and head and neck region, and
rarely occurring in the pericardium. Case presentation: We report a
7-year-old boy was admitted to the hospital with recurrent fever and
chest pain over the past four months. A cardiac magnetic resonance
imaging (MRI) revealed a tumor beneath the heart in the pericardial, and
we surgical resection it completely. The postoperative histopathological
examination resulted in a diagnosis of monophasic spindle cell type
synovial sarcoma. After two weeks of hospitalization, the patient was
discharged. Three months after discharge, the positron emission
tomography (PET/CT) scans did not show any signs of recurrence.
Conclusion: Pericardial synovial sarcoma is a rare disease that is
detected early, and complete resection improves patient survival. We
recommend CT be performed in patients with recurrent fever and sizeable
pericardial effusion to rule out possible pericardial synovial sarcoma
considering the echocardiography limitations.
