Radiological examination in a young adult revealed the presence of an opacity facing the second left arch of the heart shadow. This finding associated with data from computed tomography suggested a diagnosis of a thymic tumor. Surgical exploration demonstrated a defect in the left pericardium through which there was a rhythmic protrusion of the auricle and fatty tissue. Aplasia of the pericardium is rarely observed, and usually involves its left side. It results from premature atrophy of the left Cuvier's canal, and is associated with cardiac or pulmonary anomalies in half of the cases. Diagnosis should be suggested by the abnormal appearance of the second left arch, very often clinically asymptomatic, and is confirmed when the creation of a pneumothorax produces a simultaneous pneumopericardium. A thoracic scan can visualize the left auricular hernia beyond the mediastinal limits. However, pericardial aplasia must remain a differential diagnosis of pathological opacities in the middle mediastinum.

We treated two cases of pericardial rupture from blunt chest trauma. Case 1: A 55-year-old male was injured in an automobile accident. He recovered from the left hemothorax by tube drainage. One year and two months after the trauma, a left pericardial rupture was found during an operation for a left diaphragmatic hernia. As the epicardium adhered firmly to the pericardium, the ruptured pericardium was not sutured. Case 2: A 46-year-old man fell from a tree five meters in height. Chest radiography showed multiple right rib fractures, a pelvic fracture, pneumopericardium, and right hemopneumothorax. After four days, we performed a thoracoscopic examination under local anesthesia. The thoracoscopy revealed a rupture as large as an egg in the right pericardium anterior to the phrenic nerve. Judging from the size of the rupture, cardiac luxation was suspected not to have occurred. So the defect was not repaired. These two patients were discharged uneventfully without cardiac luxation. In the future, the accumulation of thoracoscopic findings may provide adequate information for judging the indication of operative repair in pericardial ruptures.

A massive incarcerated hiatal hernia is a frequent finding in elderly people. The aim of this report has been to review from 1987 to 1992 the clinical aspects, therapeutic options and results of surgical treatment in a series of twenty-eight patients (23 females and 5 males) with a large incarcerated hiatal hernia. Age averaged 66 +/- 10 years; thirteen patients (46.5%) had a sliding type of hernia, 8 (28.5%) a mixed one, and 7 (25%) a paraesophageal hernia. In 9 patients (32%) there was a chronic volvulus of the incarcerated stomach. Twenty-seven patients underwent elective repair; one patient developed a perforated gastric ulcer into the pericardial sac with pneumopericardium and died before surgery. The surgical technique included reduction of the hernia, closure of the hiatus and an antireflux procedure (Nissen 25, Toupet 1 and Dor 1). There was no mortality and the morbidity (18%) was not directly related to the surgical procedure. In our series there were no cases of acute volvulus requiring emergency surgery. Our results suggest that surgical correction of massively incarcerated hiatal hernias is well tolerated in the elderly, it relieves symptoms, and avoids potential serious complications.

A 29-year-old man presented to the accident and emergency department complaining of a sudden onset of chest and upper abdominal pain. He had a past history of intravenous drug abuse and a previous stab wound to the left hypochondrium that had required laparotomy. On arrival he was distressed with grunting respiration. Initial chest X-ray showed a pneumopericardium. Despite titrated doses of opiate analgesia he became increasingly distressed, agitated and dyspnoeic. Repeat chest X-ray demonstrated an increase in the volume of air present within the pericardial sac. His clinical condition improved rapidly after needle pericardiocentesis decompression. A water-soluble contrast swallow revealed a diaphragmatic hernia with a filling defect in the greater curve of the stomach and contrast medium entering the pericardial sac. A thoraco-abdominal laparotomy confirmed a pre-existing diaphragmatic defect from the previous stab wound, with surrounding adhesions. A small portion of the stomach had herniated through this defect with a perforated gastric ulcer communicating directly into the pericardial sac.
