Malignant rhabdoid tumor of the heart in an infant
Insights
This case report details the first infant diagnosed with a malignant rhabdoid tumor of the heart, a rare primary cardiac malignancy. Despite chemotherapy, the infant succumbed to the aggressive tumor.
Area of Science:
- Pediatric Oncology
- Cardiovascular Pathology
- Medical Imaging
Background:
- Pericardial effusion in infants can indicate serious underlying conditions.
- Primary cardiac malignancies are exceedingly rare in pediatric populations.
- Malignant rhabdoid tumors are aggressive neoplasms with a propensity for early metastasis.
Abstract:
A 6-month-old infant presenting with pericardial effusion was found to have a malignant rhabdoid tumor of the heart. As visualized by two-dimensional echocardiography and subsequently by contrast-enhanced computerized axial tomographic scanning, the tumor arose from the left ventricular free wall and grew into the pericardial space. Despite two courses of single-agent chemotherapy with doxorubicin, the child died 3 months later. This is the first reported case of malignant rhabdoid tumor of the heart, and the fifth case of a primary cardiac malignancy in an infant.
