Medical Image of the Week: Hydropneumothorax

Figure 1. Gastrograffin Esophagram revealing the presence of contrast in the right pleural space (arrow).

Figure 2. Chest CT revealing right hydropneumothorax containing Gastrograffin. Note the presence of Gastrograffin in the esophagus as well as pleural space (arrow).

Figure 3. Chest CT showing a communicating channel between the esophagus and right pleural space (arrow).

A 67-year-old woman who underwent a robotic laparoscopic surgical repair secondary to a large paraesophageal hernia with gastric volvulus. Post-operatively, she developed respiratory distress and a chest CT revealed a large right hydropneumothorax. A Gastrograffin esophagram was done showing Gastrograffin in the esophagus, stomach as well as in the right pleural space suggesting an esophageal-pleural fistula (Figure 1). A chest tube was placed and contrast was present revealing a esophageal-pleural fistula (Figures 2 and 3).

Esophageal perforation should be considered in all patients with unexplained chest pain. Rapid recognition and diagnosis is key as delay in treatment is associated with increased mortality and morbidity (1). Causes of esophageal perforations include upper endoscopy, Boerhaave’s syndrome, foreign body ingestion, trauma, malignancy and intra-operative injury (2). Treatment depends on the location and the extent of the perforation as surgical intervention is the gold standard.

Medical Image of the Week: Boerhaave's Syndrome During Colonoscopy

A 76-year-old woman with no significant past medical history underwent outpatient screening colonoscopy. The procedure was difficult due to a tortuous colon and only multiple diverticula were visualized. She vomited once during the procedure. In the immediate postoperative period, she complained of neck swelling. Her vital signs were stable. On examination, right sided neck and facial swelling with palpable crepitations were noticed as well as coarse breath sounds heard on auscultation of both lung fields. Immediate chest X-ray (Figure 1) was obtained which showed bilateral subcutaneous emphysema extending from the supraclavicular area and above to the neck. Subsequent thoracic CT scan showed extensive subcutaneous air within the soft tissues of the neck bilaterally, extending into the mediastinum and along the anterior chest wall (Figure 2). An esophagram (Figure 3) revealed a focus of oral contrast actively extravasating approximately at 2.5 cm above the gastro-esophageal junction consistent with a small perforation. She underwent left thoracotomy with esophageal repair. Further hospital course was uncomplicated and she was discharged to a sub-acute rehabilitation facility. 

Boerhaave's syndrome is a spontaneous perforation of the esophagus due to sudden increase in intra-esophageal pressure combined with negative intrathoracic pressure caused by straining or vomiting (1). The tear usually occurs at the left posterolateral wall of the lower third of the esophagus. Usually patients have severe retching and vomiting which is followed by excruciating retrosternal chest and upper abdominal pain after perforation. Other manifestations are odynophagia, tachypnea, dyspnea, fever, and shock. On physical examination subcutaneous emphysema (crepitation) is an important diagnostic feature. Chest radiograph usually reveals mediastinal or free peritoneal air as the initial manifestation, and hours to days later pleural effusion with or without pneumothorax, widened mediastinum, and subcutaneous emphysema are typically seen. The diagnosis of esophageal perforation can also be confirmed by water-soluble contrast esophagram using Gastrograffin, which reveals the location and extent of extravasation of contrast. Treatment depends upon the size and location of the perforation. Surgery is generally required for thoracic perforations while cervical perforations can often be managed conservatively with continuous nasogastric suction, intravenous broad-spectrum antibiotics, and parenteral nutrition.

Medical Image of the Week: Esophageal-Pleural Fistula

Figure 1. Esophagram showing fistulous tract formation from the distal esophagus just proximal to the gastroesophageal junction, with possible communication with the pleural space.

Figure 2. CT scan of the chest showed empyema with LLL pneumonia and air in the mediastinum.

Figure 3. Three- dimensional CT scan of the chest showed fistulous tract close to the gastroesophageal junction.

A 51 year old woman with rheumatoid arthritis, diabetes mellitus and gastroesophageal reflux disease had a transoral incisionless fundoplication for a hiatal hernia 6 months before admission. She presented with left lower lobe pneumonia and empyema. The esophagram showed a fistulous tract communicating with the pleural space (Figure 1). CT scan of the chest also showed air in the mediastinum (Figure 2) as well a fistulous tract in the three dimensional reconstruction (Figure 3). Esophagogastroduodenoscopy (EGD) showed an esophageal defect 5 cm above the gastroesophageal junction. An esophageal stent was placed with success.
