Hiperreacción luteínica durante el tercer trimestre del embarazo. Reporte de caso / Hyperreactio luteinalis during the third trimester of pregnancy. A case report

RESUMEN La hiperreacción luteínica es una entidad poco frecuente del embarazo, que se caracteriza por aumento bilateral y funcional de los ovarios con presencia de quistes de paredes finas. Varias hipótesis sugieren que es causada por el aumento de las concentraciones o la sensibilidad ovárica a la gonadotropina coriónica. La mayoría no presenta síntomas o complicaciones del embarazo, y el diagnóstico se realiza en forma accidental por ecografía de rutina. Es una condición benigna rara, suele autolimitarse y se resuelve espontáneamente después del parto. Sin embargo, a veces no pueden ser diferenciados de los tumores malignos de ovario sin un examen histológico. La cirugía está indicada cuando existen complicaciones como torsión ovárica o peritonitis por hemorragia o rotura. Se presenta un caso de hiperreacción luteínica durante el tercer trimestre del embarazo.

ABSTRACT Hyperreactio luteinalis is a rare entity of pregnancy characterized by bilateral and functional enlargement of the ovaries that present thin-walled cysts. Several hypotheses suggest it is caused by increased concentrations or ovarian sensitivity to chorionic gonadotropin. Many cases do not present symptoms or complications during pregnancy, and diagnosis is done accidentally by routine ultrasound. This rare benign condition is usually self-limited and resolves spontaneously following delivery. However, some have to be differentiated from malignant ovarian tumors by histological examination. Surgery is indicated when there are complications such as ovarian torsion or peritonitis due to hemorrhage or rupture. We present a case of hyperreactio luteinalis during the third trimester of pregnancy.

A Case of Spontaneously Regressed Hyperreactio Luteinalis Occurred in Normal Pregnancy / 대한산부인과학회잡지

Hyperreactio luteinalis rarely occurs in normal single pregnancy. About 50 such cases have been published. It is usually occurs in trophoblastic disease. This case is a huge hyperreactio luteinalis that detected in gestational age 16 weeks. The patient delivered a normal female infant at 41th week of gestation without any mass related problems. The hyperreactio luteinalis was a benign condition in itself with normal spontaneous remission in two months after delivery. Also the level of elevated human chorionic gonadotropin became normal. The conservative management was appropriated. This case is noteworthy because it resulted in spontaneous regression without surgical intervention and conserved ovarian tissue.

Hyperreactio luteinalis associated with a normal singleton pregnancy / 대한산부인과학회잡지

Hyperreactio luteinalis is a rare disease characterized by marked cystic enlargement of the ovary due to multiple benign theca lutein cyst. The cause of this disease is not well known but is believed to be induced by high serum levels of human chorionic gonadotropins (hCG). It occurs usually in gestational trophoblastic disease, multiple pregnancies, and rarely in normal pregnancy. In nature, hyperreactio luteinalis is a benign condition. Therefore, the appropriate management is conservative, but surgical intervention is definitely indicated to remove infarcted tissue, control hemorrhage, or decrease androgen production in virilized patients. Here we report a case of hyperreactio luteinalis which was diagnosed at 11 weeks gestation. Lower abdominal pain was developed and progressed. Emergent right wedge oophorectomy and left salpingoophorectomy was performed due to probable torsion of left ovarian cyst and the pregnancy maintained. Theca lutein cysts were confirmed on pathologic examination.

A Case of Hyperreactio Luteinalis / 대한주산의학회잡지

Hyperreactio luteinalis(HL)referes to moderate to marked cystic bilateral enlargement of ovaries due to benign theca lutein cysts, usually related to hydatidiform mole or choriocarcinoma. After its first description by Berger in 1938, almost 53 cases of HL unassociated with trophoblastic disease have been reported in the literature. We encountered one such case in a 34 years old female which was incidentally diagnosed during cesarean section at term.

A Case of Hyperreactio Luteinalis in Normal Pregnancy / 대한산부인과학회잡지

We report a case of hyperreactio luteinalis in a patient with normal singleton pregna-ncy. In the 10th week of gestation, the patient developed lower abdominal pain accompanied by abdominal distension. Ultrasonography revealed bilateral ovarian cysts. Right salpingo-oophorectomy was performed due to torsion of right ovarian cyst. The pathologic diagnosis was corpus luteal cyst. Any signs of maternal virilization were not seen. The patient deliv-ered a normal male infant at 39th week of gestation. As hyperreactio luteinalis is a benign condition in itself with normal spontaneous remission after delivery, the conservative man-agement may be appropriate.
