Intracardiac leiomyomatosis: iliac vein to right-ventricular outflow tract

Clinical features and prognostic factors analysis of intravenous leiomyomatosis

Background

The treatment and prognostic factors of intravenous leiomyomatosis (IVL) remain lacking systematic evidence.

Methods

A retrospective study was conducted on IVL patients from the Qilu Hospital of Shandong University, and IVL cases were published in PubMed, MEDLINE, Embase and Cochrane Library databases. Descriptive statistics were used for the basic characteristics of patients. The Cox proportional hazards regression analysis was used to assess the high-risk factors related to the progression-free survival (PFS). The comparison of survival curves was performed by Kaplan-Meier analysis.

Results

A total of 361 IVL patients were included in this study, 38 patients from Qilu Hospital of Shandong University, and 323 patients from the published literature. Age ≤45 years was observed in 173 (47.9%) patients. According to the clinical staging criteria, stage I/II was observed in 125 (34.6%) patients, and stage III/IV was observed in 221 (61.2%) patients. Dyspnea, orthopnea, and cough were observed in 108 (29.9%) patients. Completed tumor resection was observed in 216 (59.8%) patients, and uncompleted tumor resection was observed in 58 (16.1%) patients. Median follow-up period was 12 months (range 0-194 months), and 68 (18.8%) recurrences or deaths were identified. The adjusted multivariable Cox proportional hazard analysis showed age ≤45 years (vs. >45) (hazard ratio [HR] = 2.09, 95% confidence interval [CI] 1.15-3.80, p = 0.016), and uncompleted tumor resection (vs. completed tumor resection) (HR = 22.03, 95% CI 8.31-58.36, p < 0.001) were high-risk factors related to the PFS.

Conclusion

Patients with IVL have a high probability of recurrence after surgery and a poor prognosis. Patients younger than 45 years and with uncompleted tumor resection are at higher risk of postoperative recurrence or death.

Intravenous leiomyomatosis with intracardiac extension: an unusual presentation of uterine leiomyoma and evaluation with 256-slice dual-source multidetector CT and cardiac MRI

We report a case of a 40-year-old woman who presented with breathlessness, palpitations and vague pelvic pain for 6 months. The dyspnoea was non-exertional and episodic. She was a non-diabetic, non-hypertensive and had no history of prior surgeries. ECG and chest radiograph were normal. Cardiac MRI and 256-slice dual-source multidetector CT evaluation revealed the presence of a uterine and left adnexal mass with intravenous extension into the inferior vena cava via the gonadal veins, and further cephalad extension into the right atrium and ventricle. The patient was referred to the cardiothoracic surgery department and underwent two-stage surgical procedures. The first stage consisted of thoracotomy and tumour removal from the right atrium and inferior vena cava. In the second stage, hysterectomy and bilateral salpingo-oophorectomy was performed. The histological analysis of the excised specimen was consistent with an intravascular leiomyoma.

Intravenous leiomyomatosis with intracardiac extension - a review of diagnosis and management with an illustrative case

Intravenous leiomyomatosis with intracardiac extension is an uncommon pathologic progression of uterine leiomyomata. It is a histologically benign condition, however due to interfence with right sided cardiac function patients may present with marked cardiovascular compromise and present a diagnostic dilemma to clinicians who are unfamiliar with this condition. Given the rarity of this condition, experience in individual institutions is usually limited to a few cases. We present an illustrative case and provide a review of the clinical presentation, preoperative assessment, operative approach, pathology and postoperative issues. The importance of a multidisciplinary approach to diagnosis and management is highlighted. Operative management aims to completely resect all tumour in the safest manner for the patient, most commonly via single or two stage operation. Where complete resection is achieved, recurrence appears to be a rare event.

Multinodular leiomyoma of the esophagus with internodular hydropic degeneration and bulbous serosal protrusions similar to cotyledonoid uterine leiomyoma

Leiomyoma is the most common benign tumor of the esophagus, and usually occurs as a solitary mass. We report a case of esophageal leiomyoma which shows multinodular growth pattern with bulbous serosal protrusions. The patient was a 26-year-old woman who had an esophageal ulcerated mass near the gastroesophageal junction. Clinical findings were consistent with carcinoma of the gastric cardia. Based on the clinical diagnosis, total gastrectomy with distal esophagectomy was performed. Histologic appearance of the resected specimen was consistent with leiomyoma which had a multinodular growth pattern.
