Summary

This summary is machine-generated.

Hyperreactio luteinalis (HL) is a rare pregnancy complication causing enlarged ovaries due to elevated beta-human chorionic gonadotropin (B-hCG). Conservative management is key, as HL typically resolves postpartum, preventing unnecessary surgeries.

Reproductive Endocrinology
Maternal-Fetal Medicine
Gynecologic Pathology

Background:

Hyperreactio luteinalis (HL) is a rare, benign ovarian hyperstimulation condition during pregnancy.
It is characterized by bilateral ovarian enlargement due to multiple theca lutein cysts.
Elevated levels of beta-human chorionic gonadotropin (B-hCG) are the primary cause.

Observation:

A case of a 32-year-old woman presenting with incidentally discovered, progressively enlarging multicystic ovaries during the third trimester of pregnancy.
The patient exhibited signs of hyperandrogenism and abdominal pain.
Ultrasound revealed bilateral ovarian enlargement with a characteristic "spoke wheel" appearance.

Findings:

The ovarian enlargement was attributed to Hyperreactio luteinalis, confirmed by elevated B-hCG levels.
Despite significant ovarian size, the condition was managed conservatively.
The patient experienced spontaneous resolution postpartum.

Implications:

Familiarity with HL's natural history is crucial for obstetricians to avoid iatrogenic harm from unnecessary surgical interventions.
Conservative management is recommended for HL, emphasizing expectant observation.
Increased use of prenatal ultrasound necessitates awareness of HL to prevent misdiagnosis and overtreatment.
