“…The rupture of RAML can occur at various stages of pregnancy. One study reported that the mean gestational age of patients was 27.7 wk, and the average tumor size was 10.1 cm at the time of diagnosis[ 7 ]. Pregnancy also plays a role in the growth and rupture of RAML, but the mechanism is not clear.…”

BACKGROUND Spontaneous rupture and hemorrhage of renal angiomyolipoma (RAML) is a life-threatening clinical emergency. When it occurs during pregnancy, it is compared to a “bomb explosion,” which makes the diagnosis and treatment more challenging. An ultrasound examination is a quick and safe examination with the benefit of no radiation exposure, which is always preferred for pregnant women. Currently, cases of spontaneous rupture and hemorrhage of RAML during pregnancy are rare, as is the diagnostic value and characteristics of ultrasound. The lack of understanding of the condition among ultrasound doctors makes it prone to misdiagnosis. In this study, we present the case of a pregnant woman who was preliminarily diagnosed with spontaneous rupture and hemorrhage of the left RAML using ultrasound and discuss the ultrasound characteristics. CASE SUMMARY A 38-year-old woman in her 19 th wk of pregnancy (G2P1) was referred to our clinic for a sudden, persistent pain on the left side of the waist. She had not undergone any previous related abdominal examination. Ultrasound of the urinary system revealed a giant nonhomogenous lump in the left kidney area. The diagnosis was considered spontaneous rupture and hemorrhage of the left RAML in pregnancy via ultrasound. Her left-side waist pain continued to be intense. Subsequently, she underwent computed tomography, which led to the same diagnosis. Based on many factors, the patient underwent left nephrectomy after the induction of labor. The pathological result was the rupture and hemorrhage of a vascular leiomyoma lipoma. CONCLUSION Ultrasound examination plays an important role in the diagnosis of the spontaneous rupture and hemorrhage of RAML during pregnancy.

“…In addition, the higher rate of growth during the gestational period, the higher incidence in women in menacme and the rare onset before puberty suggest that this type of tumor is hormone-dependent. 14,15,18,19 More than 25% of RAMLs have estrogen and progesterone receptors, as do lung AMLs. Therefore, the growth of this type of tumor can be stimulated during pregnancy or by the intake of oral contraceptives.…”

Angiomyolipomas (AMLs) are rare benign tumors derived from mesenchymal tissue and composed of varying degrees of adipose tissue, muscle and blood vessels. Renal AMLs (RAMLs) are the result of a sporadic event, and, in most of cases, the diagnosis is usually incidental, but hemorrhage and shock may be present. During pregnancy, the size of AMLs may increase and they may rupture, probably due to the high expression of hormone receptors, and the increase in maternal circulation and abdominal pressure. The authors present a case of a woman with ruptured RAML submitted to urgent endovascular treatment four days after giving birth by cesarean section.

“…Причины ее развития в настоящее время до конца не ясны. Есть данные о высоком содержании в опухоли рецепторов к эстрогену, прогестерону [3]. Видимо, поэтому ангиомиолипома в 2,6-10 раз чаще поражает женщин, этим же объясняются быстрый рост опухоли во время беременности и высокая вероятность ее разрыва в этот период, причем нет корреляции между размерами и вероятностью разрыва опухоли [3].…”

Полагаем, что наличием прогестероновых рецепторов в ангиомиолипоме обусловлена также невозможность использовать препараты прогестерона, которые рекомендуются для сохранения беременности и широко назначаются на различных сроках гестации, -применение этих препаратов может стать причиной роста еще не диагностированной опухоли.…”

Objective of the Paper: To present a clinical case of renal angiomyolipoma rupture during pregnancy and describe the steps in its diagnosis and a treatment approach that led to a favorable clinical outcome. Key Points: Spontaneous rupture of the kidney is a rare condition with severe complications, especially during pregnancy. One possible cause of this condition is rupture of a renal tumor (angiomyolipoma), with pregnancy being a trigger for the tumor growth of this kind of neoplasm. Because it is rare, angiomyolipoma is most often detected incidentally during an examination. It is mainly diagnosed by renal ultrasound. This paper discusses the main characteristics of angiomyolipoma, describes a clinical case of this tumor in a pregnant woman, and provides information about a promising method for preventing angiomyolipoma proposed by foreign authors. Conclusion: Assessment of the urinary tract should be done routinely during one of the prenatal ultrasound screenings, as a preventive measure against urinary tract emergencies in pregnant women. Keywords: spontaneous rupture of the kidney, renal angiomyolipoma, pregnancy.
