Ultrasound Presentation of a Disseminated Fetal and Neonatal Rhabdoid Tumor

الملخص EN

This is a case report of a disseminated fetal rhabdoid tumor discovered at 32 weeks of gestation in a 29-year-old woman on immunosuppressive therapy.

The mother consulted for a decrease in fetal movement.

Fetal ultrasound showed signs of a disseminated tumor affecting the left armpit, liver, spleen, and limbs.

A caesarian section was performed because of signs of fetal distress.

Immunohistochemical analysis of a fetal biopsy showed deletion of the SMARCB1 gene.

Pathological analysis of the placenta showed a rhabdoid tumor invading both fetal and maternal compartments.

The mother underwent a whole-body MRI, and no metastasis was found.

To the best of our knowledge, this is the first report of a disseminated rhabdoid tumor invading both fetal and maternal compartments.
