Sacrococcygeal teratoma (SCT) is a rare germ cell neoplasm in the newborn with a higher incidence rate in female baby. SCT are diagnosed on ultrasound as exophytic masses rapidly growing in utero. Most of Sacrococcygeal teratoma are non-cancerous and increasing metabolic demands of the rapid but disproportionately growing tumor results in high risk of perinatal and obstetric complications.
At birth, SCT dystocia, intra tumoral haemorrhage or tumoral rupture are of major concern and are life threatening. Timely management becomes the key for a good perinatal outcome.
A 32-year-old, multi gravida mother visited us for regular antenatal checkups. Her routine blood investigations were normal. Anomaly scan was done at 19 weeks of gestation showed a 24 cc exophytic mass arising from the sacrum with no obvious involvement of spinal canal. No other associated malformations noted. The Tumor volume: Fetal Weight Ratio (TFR) was 0.069, which suggested a good fetal outcome.
The risks and complications of continuing pregnancy were explained to the couple & they opted to continue.
