1. Abstract
1.1. Background
Leiomyosarcoma of the inferior vena cava (IVC) is a rare malignant tumor. Surgical resection is currently the only potential curative treatment. According to the treated experience of one patient in our hospital, we present our opinions as below.
1.2. Methods and Results
We present a case of 61-year-old woman with leiomyosarcomas in the IVC. The tumor appearance on pre-operative imaging simulated a hepatic tumor with IVC tumor thrombus. In operation, the tumor was found from IVC. The patient was underwent successful surgical treatment for a leiomyosarcoma. Pathological examination confirmed that it was a primary leiomyosarcoma of the IVC. The patient had a normal live for two years and without recurrence.
1.3. Conclusion
We encountered a rare case of a leiomyosarcoma of IVC mimicking hepatic tumor with IVC tumor thrombus and misdiagnosis. Radical surgical resection is the primay treatment for IVC leiomyosarcomas. Surgical resection followed by radiotherapy can enhance long-term survival.
