EP17.21: A case report of sacrococcygeal teratoma with bilateral theca lutein cysts

Abstract

Sacrococcygeal teratoma (SCT) is the most common congenital germ cell tumour, with an incidence of 1 in 35,000-40,000 live births and a female predominance (3:1-4:1 ratio). Hyperreactio luteinalis (HL) is a rare entity in which there is bilateral benign functional multicystic ovarian enlargement during pregnancy which is most commonly seen in the third trimester and many times it is mistaken for ovarian malignancy and inadvertently operated upon. At a tertiary referral fetal medicine unit, Cairo University we reported a case presented at 32 weeks GA pregnant in a fetus with sacrococygeal teratoma type II according to American Academy of Pediatrics, Surgical Section (AAPSS). During the scan hyperreactio lutinalis was discovered accidentally by ultrasonography. Two days later the patient gave history of spontaneous rupture of membranes, premature labour and delivered by her physician by normal vaginal delivery. The fetus was delivered with respiratory distress, underwent NICU where the baby died 4 hours later. Three months later both ovaries resolved spontaneously and become completely normal diagnosed by ultrasonography. So we must not jump into diagnosis of ovarian malignancy in these cases.
