Key result
Intraoperative TEE enables safe, complete excision of invasive pheochromocytoma without tumor embolization.
Why the study?
Extension of pheochromocytomas into the vena cava and right atrium is rare, and guidance for surgical excision is not well established.
Case Report (n=1)
Transesophageal echocardiography can be a valuable tool to guide the safe surgical excision of rare intracardiac extensions of pheochromocytomas.

TEE may aid safe excision in rare invasive pheochromocytomas; leaves open need for prospective validation.
Pheochromocytomas are rare neuroendocrine tumors, with published incidence of 2 to 8 cases per million patients per year. The extension of these tumors into the vena cava and right atrium is rarely seen. Transesophageal echocardiography may be invaluable to delineate tumor extent and characteristics, which in turn may provide a useful tool to guide intraoperative surgical approach to these uncommon masses. In the case presented in this article, we describe the role of transesophageal echocardiography in guiding a safe and complete, excision of an invasive pheochromocytoma without embolization of tumor components.

Kurian et al. (2017) conducted a case report in Pheochromocytoma (n=1). Transesophageal echocardiography was evaluated on Safe and complete excision without embolization of tumor components. Transesophageal echocardiography successfully guided the safe and complete surgical excision of an invasive pheochromocytoma without embolization of tumor components.
