| These are superficial lacerations of the intima that do not involve the media or adventitia. |
| The pathology findings consist of a cyst of gelatinous contents between the media and adventitia causing luminal compression. |
| With still greater increases in caliber, a distinct intima, media, and adventitia become recognizable. |
| The adventitia is rich in collagen bundles, and contains some cells that may be fibroblasts or macrophages. |
| The submucosa, muscularis propria and adventitia of the esophagus were normal. |
| The arteries were most susceptible, with bruising of the intima and adventitia and separation of the media from the vessel walls. |
