Metastastic Gastric Adenocarcinoma: Diagnosis through Pericardioscopy

It is estimated that the pericardium is affected by 10 to 21% of patients with neoplasms. Malignant pericardial effusion is a complication that may be related to neoplastic disease in which, if not diagnosed and conducted rapidly, it may be life threatening requiring diagnosis.
