Key result
Intraoperative TEE guides resection of a rare endometrial stromal sarcoma presenting as a right atrial cyst.
Why the study?
Low-grade endometrial stromal sarcoma presenting as a right atrial cyst has not been previously described by transesophageal echocardiography.
Case Report (n=1)
Intraoperative TEE is valuable for identifying and guiding the surgical resection of rare intracardiac masses, such as an endometrial stromal sarcoma presenting as a right atrial cyst, without the need for cardiopulmonary bypass.
TEE may enable intact resection of rare right atrial masses; single case leaves open broader adoption.
A 71-year-old woman presented with a right adnexal solid mass invading the right gonadal vein and inferior vena cava up to the hepatic veins revealed by CT and confirmed by MRI. A thin-walled cyst and a solid mass were unexpectedly found in the right atrium by transesophageal echocardiography (TEE) in the operating room. Using color Doppler and air bubbles as contrast material a circumscribed cyst was confirmed and localized close to the IVC. The cyst was connected to the mass in the inferior vena cava. The tumor, including the cyst, was removed without using cardiopulmonary bypass and described as a low-grade endometrial stromal sarcoma, a rare slowly growing tumor. This is the first TEE description of endometrial stromal sarcoma manifesting as a right atrial cyst.

Wood et al. (2011) conducted a case report in Low-grade endometrial stromal sarcoma invading the right atrium (n=1). Surgical resection using intraoperative transesophageal echocardiography (TEE) guidance was evaluated on Successful removal of the tumor and cyst. Intraoperative transesophageal echocardiography successfully identified and guided the intact resection of a rare low-grade endometrial stromal sarcoma presenting as a right atrial cyst.
