Following pulmonary infarction, three patients developed the classical signs and symptoms of the Dressler syndrome associated with persistent left pleural effusion. Each responded dramatically to corticosteroid therapy. While the pathogenesis of this "Post-Pulmonary Infarction syndrome," like the Dressler syndrome, is unclear, the response to corticosteroid therapy is both dramatic and diagnostic and may spare the patient prolonged discomfort and unnecessary diagnostic procedures.

A 75-year-old woman was admitted to hospital with haemoptysis, fever and shortness of breath. She had undergone a right video-assisted thoracoscopic surgery upper lobectomy for an apical lung cancer 4 weeks earlier, and had been treated with antibiotics for 1 week prior to admission for a suspected postoperative lung abscess. Review of preoperative imaging found that she possessed a lobar pulmonary artery variant, with postoperative imaging confirming that the right lower lobe segmental pulmonary artery had been divided alongside the upper lobe vessels. The diagnosis of a lung abscess was thus revised to a cavitating pulmonary infarct. There are numerous variations of the pulmonary vasculature, all of which have the potential to cause a range of serious vascular complications if not appreciated preoperatively. Measures to mitigate the risk of complications resulting from vascular anomalies should be considered by both radiologists and surgeons, with effective lines of communication essential to safe working.

Since the presence of "bubbly consolidation" (central lucencies) on a multi-slice computed tomography pulmonary angiography (MCTPA) is one of the highly specific imaging appearances of infarct secondary to pulmonary embolism, we investigated the ultrasound characteristics of these infarctions. In this study, 118 patients with MCTPA diagnosis of acute pulmonary embolism were enrolled. Pulmonary infarctions were detected in 21 patients (17.7%), of which 10 (47.6%) showed the typical appearance of bubbly consolidation on MCTPA. Lung ultrasound (LUS) was performed to evaluate the characteristics of the infarcts highlighted by MCTPA. The bubbly consolidations showed a very peculiar echographic aspect represented by a triangular hypoechoic consolidation with sharp margins, the absence of air bronchograms and a mostly central roundish hyperechoic area. Air lucencies within a pulmonary infarct is hypothesized to represent the coexistence of aerated non-infarcted lung with the infarcted lung in the same lobule. The ultrasound appearance confirms this hypothesis, so we named the roundish hyperechoic area the "survived lung." This picture was found in all patients with a diagnosis of bubbly consolidation on MCTPA (100%). Χ between MCTPA and LUS regarding the bubbly consolidation diagnosis is 17.18 (df = 1; p value = 0.00003). Bubbly consolidations show a very typical appearance on LUS. Their detection suggests further investigations (MCTPA or point-of-care multi-organ ultrasonography).

The purpose of this case presentation is to discuss right upper quadrant pain as an atypical presenting symptom in pulmonary infarction and review the typical computed tomography (CT) imaging features of pulmonary infarction to improve diagnostic accuracy. Pulmonary infarction results from occlusion of distal arterial vasculature within the lung parenchyma leading to ischemia, hemorrhage, and ultimately necrosis. Patients with lung infarction typically present with pleuritic chest pain and may have associated signs or symptoms of pulmonary thromboembolism or deep vein thrombosis. In this case study, a 34-yr-old female devoid of any symptoms indicative of either pulmonary embolism or deep vein thrombosis presented with right upper quadrant pain 1 mo status post open reduction internal fixation for a left ankle fracture. Multiple clinic visits spanning approximately 7 d were significant for a right lower lobe opacity seen on CT of the abdomen which was presumed to represent community acquired pneumonia as a source for the patient's RUQ pain. The patient presented to the emergency department 1 wk later (6 wk following her initial surgery) complaining of left lower extremity swelling and was subsequently diagnosed with a left lower extremity DVT via ultrasound. CT of the pulmonary arteries was negative for PE but identified a right lower lobe opacity which in retrospect was consistent with pulmonary infarction.

OBJECTIVES
The aim was to investigate (1) whether collateral bronchopulmonary circulation developing due to chronic pulmonary embolism could prevent the evolution of pulmonary infarction after induction of pulmonary venous outflow impairment; and (2) how collateral bronchopulmonary circulation developed after acute embolisation of the lung with impaired pulmonary venous outflow.
METHODS
Fifty two mongrel dogs were studied. Thirty six dogs were experimental animals and 16 were in a control group. Unilateral impairment of pulmonary venous outflow was induced by constriction of the left pulmonary veins in two groups of experimental dogs: (1) three months after and (2) one hour before bilateral embolisation of the pulmonary artery. All animals were killed 12 days after constriction. The size of the bronchial arteries was evaluated from angiograms. The diameter and the wall thickness of the arteries were measured during histology.
RESULTS
In all experimental dogs, haemorrhagic infarctions developed distally to emboli in the left lung regardless of whether the bronchial arteries were dilated before induction of pulmonary venous constriction or whether collateral circulation started to develop after pulmonary venous constriction. Constriction of the pulmonary veins was an essential factor for pulmonary infarction to develop as no infarction developed in the embolised regions of the right lungs with intact pulmonary venous outflow. Pulmonary venous constriction alone did not cause dilatation or hypertrophy of the bronchial arteries. After pulmonary artery embolisation, the same enlargement and hypertrophy of the bronchial arteries occurred both in the left lung with previously impaired venous outflow and in the right lung with intact pulmonary veins.
CONCLUSIONS
Expanded bronchopulmonary circulation did not prevent the development of infarction in the embolised region of the lung with impaired pulmonary venous outflow. Development of collateral bronchopulmonary circulation was not influenced by previously impaired pulmonary venous outflow.
