1. Pulsating, encapsulated hematoma in communication with the lumen of a ruptured vessel.
2. Ventricular pseudoaneurysm, a cardiac rupture contained and loculated by pericardium, which forms its external wall.

pseudoaneurysm

The preferred term for a false aneurysm in which the saccular dilation (“aneurysm”) does not involve all of the vessel wall layers.

Pseudoaneurysm should not be confused with phantom aneurysm (also known as aortismus abdominalis), a near-extinct term for the clinical misinterpretation of the (normal) aortic pulse as a sign of an abdominal aortic aneurysm, an error usually borne of inexperience.
