Transesophageal echocardiography is a useful modality for clearly demonstrating the multilocularity of mediastinal lymphangiomas, which may appear vague on CT scans.
May aid characterization of select mediastinal masses; leaves open prospective validation of TEE versus CT.
Lymphangioma is a rare benign lesion; when detected in adults, it is often asymptomatic and mediastinal. We present a case of posterior mediastinal lymphangioma in an adult that was detected accidentally by echocardiography. It is the first time that echocardiography of mediastinal lymphangioma is reported along with the findings in chest X-ray, computed tomography (CT) scan, and contrast-enhanced multi-slice CT. The cystic type of lymphangioma usually shows vague intensity on CT; however, its multilocularity could be clearly demonstrated by transesophageal echocardiography (TEE).
