Intrathoracic Accessory Lobe of Liver Masquerading as a Paraesophageal Mass.
Heterotopic liver tissue is a relatively rare finding, which has historically been discovered incidentally during surgery or at autopsy. However, we present a 28-year-old woman who presented to the emergency department with shortness of breath and stabbing chest pain. An emergent CT angiogram of the chest was performed, which incidentally revealed a mediastinal paraesophageal mass. Subsequent endoscopic ultrasound showed a hypoechoic area that appeared to connect to the liver. A liver/spleen scan with SPECT/CT with Tc sulfur colloid demonstrated that the mass was paraesophageal heterotopic liver tissue with a connection to the orthotropic liver by a small stalk.
