Peritoneopericardial diaphragmatic hernia

In this defect there is a persistent communication between the pericardial and peritoneal cavities, which permits abdominal organs to enter the pericardial sac (Reed, 1987). The extent of herniation is variable, and clinical signs may occur within weeks of birth or after several years. Often the hernia is asymptomatic (Evans & Biery, 1980).

Pericardial cysts

These are usually found at the apex of the parietal pericardium, usually lying within the pericardial space. The clinical signs may be similar to pericardial effusion and treatment is by surgical excision which carries a good prognosis (Reed, 1987).
