Combined prenatal ultrasound and magnetic resonance imaging in an extensive congenital fibrosarcoma: a case report and review of the literature.

OBJECTIVE

Tumors of congenital origin differ in their symptoms and signs, predominant location and prognosis from those occurred later in childhood. To determine whether the prognosis of congenital (infantile) fibrosarcoma in the retroperitoneum, an extremely rare form of soft tissue malignant tumor, can be assessed prenatally.

METHODS

We describe a case of this condition diagnosed in utero, including the assessment of the tumor behavior by ultrasound and magnetic resonance imaging. We also review the English language literature in Medline over the past 10 years and describe the management options available in such cases.

RESULTS

Our case had precise prenatal findings revealed unfavorable conditions such as bulky tumor mass, spinal metastasis and pulmonary hypoplasia.

CONCLUSION

Fetal imaging studies could accurately identify the invasion of tumor. The outcome is usually poor, especially for those fetuses affected by an axial location of the tumor.
