| Abstract|| |
Spontaneous intraleiomyoma hemorrhage, perforation, and hemoperitoneum are very rare complications of uterine leiomyoma. We report a case of postmenopausal woman who presented with acute abdomen found to have intraleiomyoma hemorrhage, perforation, and hemoperitoneum. Our case also illustrates the computed tomography findings of such complications of uterine leiomyoma.

| Introduction|| |
Uterine leiomyomas (fibroids) are the most common pelvic tumors affecting females in the fertile age group.  These benign tumors are hormone-dependent, responding to both estrogen and progesterone; they often increase in size during pregnancy and usually decrease in size after menopause.  Acute complications of fibroids are rarely seen but may be serious.  Spontaneous hemoperitoneum due to fibroid rupture is a rare entity with less than 100 cases reported in the literature. , Intratumor massive bleeding leading to hypovolemia is extremely rare. Only two cases were reported by Koide et al., and Manopunya et al., just after delivery. In this case report, we report the case of spontaneous uterine intraleiomyoma hemorrhage, perforation, and hemoperitoneum in postmenopausal woman diagnosed by computed tomography (CT) and confirmed by laparotomy and pathological diagnosis.
| Case Report|| |
A 55-year-old multiparous postmenopausal woman presented to our emergency department with acute sudden lower abdominal pain for 2 h associated with dizziness. She denied trauma or vaginal bleeding and has no other associated symptoms. Her last menstrual period was 1 year back. Her medical history is significant for uterine fibroids only. On general examination, she had mild pallor. Her vital signs were stable. Abdominal examination revealed distension of lower abdomen with diffuse tenderness and guarding. A firm tender mass was felt arising from the pelvis. Her lab results were within normal limits except hemoglobin level was 10.4 g/dL. CT scan of abdomen and pelvis with intravenous contrast was performed which revealed a large uterine mass arising from the fundus with heterogeneous appearance and active contrast extravasation inside it [Figure 1] and [Figure 2]. It also showed an evidence of perforation at the fundus and high density moderate-free fluid (hemoperitoneum) [Figure 3] and [Figure 4]. A repeated hemoglobin level after 2 h was 8.5 g/dL. Therefore, two packed red blood cells were given and the patient was taken emergently to operating room. Laparotomy was done and revealed enlarged uterus with fundal perforation and clot and tissue coming out from the perforation site as well as about 1 L of hemoperitoneum. A total hysterectomy with bilateral salpingo-oophorectomy was performed. The patient recovered after surgery with uneventful postoperative course and discharged home.

Gross pathological examination revealed enlarged uterus measured 15 × 14 × 9 cm. Bisected uterus showed solid mass measured 15 × 12 × 7 cm arising from the fundus with evidence of perforation. On microscopic examination, a cellular leiomyoma with evidence of hemorrhagic infarction is found. No malignant cells were identified. The uterine cervix, Fallopian tube More Detailss, and ovaries were normal.
| Discussion|| |
The common causes of acute abdomen in cases of fibroid uterus include torsion of subserous fibroid, red degeneration, torsion of uterus along with the fibroid, and sarcomatous degeneration.  Large fibroids often degenerate as they outgrow their blood supply. The various types of degeneration include hyaline, myxoid, cystic, and red degeneration.  Red or carneous degeneration is occasionally seen in a fibroid, which develops most frequently during pregnancy.  Sudden intraperitoneal hemorrhage in a case of fibroid uterus can also present as acute abdomen.  The bleeding is likely to occur from torn enlarged veins coursing over the surface of subserous leiomyomas, resulting in hemoperitoneum and hypovolemic shock. 
Ultrasound is often the initial diagnostic imaging modality for suspected complications of fibroids. A simple fibroid is usually seen as a hypoechoic lesion that may be well-defined and arising within the surrounding myometrium. Fibroids can also demonstrate posterior acoustic enhancement or attenuation without any calcification. Degeneration of fibroids gives a more complex ultrasound appearance with areas of cystic change and Doppler can show circumferential vascularity. Fibroids that are torsed or are necrotic will show absence of flow on Doppler ultrasound.  CT is not the primary modality for diagnosing or evaluating fibroids; however, fibroids are often found incidentally at CT. Therefore, familiarity with their various CT appearances is important.  The typical finding is a bulky, irregular uterus, or a mass in continuity with the uterus. Degenerate fibroids may appear complex and contain areas of fluid attenuation.  Magnetic resonance imaging is highly accurate in evaluating leiomyoma size, number, location, and presence or extent of degeneration, but it requires a stable patient and may be difficult to perform in a timely fashion in the emergency department. 
Management is both surgical and supportive. Intravenous fluids and blood should be infused for significant blood loss and gynecology should be consulted immediately. The definitive treatment is surgical, requiring vessel repair and/or myomectomy. 
Alternative to surgery, percutaneous emboilzation of uterine artery has become established treatment for nonacute uterine hemorrhage. It is minimally invasive and also maintained patient's fertility. In addition, percutaneous emboilzation of internal iliac arteries branches has proven effectiveness in the emergency treatment of pelvic hemorrhage, resulting from trauma and other causes. It is also an effective treatment to control intractable uterine hemorrhage secondary to uterine fibroids. 
Our patient underwent total hysterectomy with bilateral salpingo-oophorectomy because of the increased risk of sarcomatous degeneration of the uterine fibroids at her age.
| Conclusion|| |
Our case report illustrates the importance of CT in emergency setting to correctly diagnose uterine intraleiomyoma hemorrhage, perforation, and hemoperitoneum, which optimized the surgical approach and management.
