Multimodality Imaging of an Unusual Case of an Obstructive Intracaval Mass by an Aberrant Liver
A 40-year-old woman presented with recurrent chest pain. Past medical history was positive for schizoaffective disorder, polysubstance abuse, and gestational diabetes mellitus. The physical examination was unremarkable. Results of an ECG and a test for cardiac enzymes, including troponins, were negative.

Transesophageal echocardiography confirmed the mass and showed it to be arising from the distal IVC near the right hepatic vein entry (Figure 1B).
Magnetic resonance imaging showed …
