RESUMEN
RATIONALE: Anti-glomerular basement membrane (anti-GBM) disease during gestation is sparse and even rarer when combined with bilateral large corpus luteum cysts. In this case, we report a case of anti-GBM disease in the early stage of pregnancy with ruptured newly formed bilateral large corpus luteum cysts. PATIENT CONCERNS: A 24-year-old female was initially diagnosed with anti-GBM disease. During treatment, abdominal distention and vaginal bleeding successively staged. The results of the first gynecological ultrasound and abdominal CT were negative. DIAGNOSIS: Based on the dynamic imaging change of the ovaries, the elevated human chorionic gonadotropin (hCG) and sex hormones, and the pathological findings, a diagnosis of anti-GBM disease with rupture of the newly formed bilateral corpus luteum cysts during early pregnancy was considered. INTERVENTIONS: The patient was treated with corticosteroids, plasma-exchange along with intensive hemodialysis. Then, to confirm the diagnosis, laparoscopic debulking of bilateral ovarian cysts and curettage were performed. OUTCOMES: After treatment, the anti-GBM antibody titer declined and the condition of the patient was still stable 2 months following discharge. LESSONS: As clinicians, we should be aware that even if the first imaging tests are negative, the relevant indicators should be reviewed dynamically based on the condition of the patients. Additionally, this case raised the question of whether anti-GBM disease was associated with pregnancy and giant corpus luteum cysts, which needs further investigations.
