Puncion intraútero guiada por ecografía de un teratoma sacrococcígeo predominantemente quístico asociado a compresión de la vía urinaria

Sacrococcygeal teratoma (SCT) is the most common tumor in the neonatal period. Approximately 15% of these tumors are predominantly cystic. Although the prognosis of cystic SCT is more favorable than that of solid SCT, cystic forms are also associated with higher perinatal morbidity and mortality due to their potential large size, which can increase the risk of prematurity and compression of pelvic structures. When a cystic SCT compresses the urinary tract, percutaneous ultrasound-guided needle drainage appears to be a safe procedure that allows resolution of the obstruction and minimizes the risk of prematurity and soft tissue dystocia.
