Prenatal detection of an extra-adrenal neuroblastoma with hepatic metastases

Imaging of solid congenital abdominal masses: a review of the literature and practical approach to image interpretation

Fetal abdominal tumors are rare, usually benign, and cause a great deal of anxiety for expectant parents and the physicians counseling them. In this paper the author reviews the most common fetal abdominal tumors in the liver (hemangioma, mesenchymal hamartoma, hepatoblastoma, metastases) and the kidney (congenital mesoblastic nephroma, Wilms tumor, malignant rhabdoid tumor, and clear cell sarcoma), and suprarenal mass lesions (adrenal neuroblastoma, adrenal hemorrhage, and subdiaphragmatic extralobar pulmonary sequestration). The author describes the imaging approach, imaging appearance and differentiating features of tumors, and differences between fetal and childhood appearances of tumors.

Metastatic neuroblastoma diagnosed on prenatal sonographic examination performed for decreased fetal movement

We report a case of fetal neuroblastoma presenting with massive liver metastasis diagnosed during the biophysical profile sonographic examination performed for decreased fetal movement. The patient presented at 37 weeks' gestation with limited fetal movement over 24 hours. Biophysical profile showed marked polyhydramnios and an enlarged abdomen filled with a homogeneous mass lesion suspicious for liver metastasis. Primary urgent cesarean section was performed revealing a cachectic neonate with a rigid and grossly distended abdomen. Neonatal evaluation confirmed the etiology of the abdominal mass to be liver metastasis from neuroblastoma. The child died on the 46th day. © 2017 Wiley Periodicals, Inc.

Fatal Congenital Retroperitoneal Neuroblastoma Diagnosed by Fetal Magnetic Resonance Imaging

Congenital extra-adrenal neuroblastoma is a rare condition, which typically has a favorable prognosis. We present a unique case of extra-adrenal retroperitoneal neuroblastoma diagnosed by fetal magnetic resonance imaging, which ultimately leads to fetal hydrops and neonatal death.
