A 60-year-old woman, with history of a resected uterine benign leiomyoma, is operated for a cystic lesion in the left lung, mimicking an hydatid cyst, and confirmed histologically as Cystic Benign Metastasizing Leiomyoma.

Introduction Hydatid pulmonary embolism (HPE) is rare but remains an etiology that needs to be considered and kept in mind, especially in endemic areas, as regards nonthrombotic embolism. Methods Between 2000 and 2014, 10 patients were treated in our department for the presence of hydatid material in the pulmonary arterial circulation. Through these 10 cases, we try to assess the radioclinical characteristics and results of the surgical treatment. Results The study included six men and four women, average age 28 years. Discovery of HPE was made following the exploration of cardiorespiratory symptoms in nine cases and was incidental in a single patient. Computed tomography angiography (CTA) of the chest directly visualized the hydatid material in the pulmonary arteries in nine cases. Surgery consisted of an embolectomy under cardiopulmonary bypass in nine cases. This embolectomy was preceded by the treatment of an embolic hydatid cyst (HC) in seven cases (HCs of the right heart chambers in six cases and a liver HC ruptured in the inferior vena cava in one case), whereas for only one patient, who presented a HC pedunculated in the right ventricle and protruding into the pulmonary artery, the cure of the cardiac location was sufficient. Only one patient died on the third postoperative day. Conclusion Endoluminal hydatid involvement of pulmonary arteries is extremely rare. CTA chest has an important contribution to the positive diagnosis. Treatment is surgical when the patient's condition allows it.

Objective The main objective of this study is to evaluate the performance of the predictive model (EuroSCORE II) on a Tunisian population to validate its use in our country. Methods This is a retrospective study of data from 418 adult patients undergoing cardiac surgery with cardiopulmonary bypass between 1 January 2015 and 31 December 2016 in the department of cardiovascular and thoracic surgery of the Sahloul University Hospital of Sousse. The EuroSCORE ΙΙ is calculated using the application validated on the site http://www.euroscore.org. The performance of the score is evaluated by analyzing its discriminative power by constructing the receiver operating characteristic (ROC) curve and analyzing its calibration using the Hosmer‐Lemeshow statistics. Results The EuroSCORE II shows good discriminative power in our population with an area under the ROC curve more than 0.7 in all study groups (0.864 ± 0.032 for general cardiac surgery, 0.822 ± 0.061 for coronary surgery, 0.864 ± 0.052 for valvular surgery, and 0.900 ± 0.041 for urgent cardiac surgery). The model appears to be calibrated as well by obtaining P values above the statistical significance level of 0.05 (0.638 for general cardiac surgery, 0.543 for coronary surgery, 0.179 for valvular surgery, and 0.082 for urgent cardiac surgery). Conclusion The EuroSCORE II presents acceptable performance in our population, attested by a good discriminative power and an adequate calibration.

We report the case of a 6-year-old boy with right main bronchus avulsion after blunt chest trauma. Reimplantation of the right main bronchus at the carina was performed via a right posterolateral thoracotomy, with satisfactory long-term morphological and functional results.

Background Infective endocarditis remains a serious condition. Left ventricular pseudoaneurysm may complicate the clinical course of infective endocarditis or occur postoperatively. Case presentation We describe a case of a pseudoaneurysm of the left ventricular lateral wall which developed one month following cardiac surgery of active endocarditis affecting aortic and mitral valves. The diagnosis was established by transthoracic echocardiography and computed tomography angiography of the chest. Urgent cardiac surgery is performed with excision of the pseudoaneurysm and direct closure of the defect. The patient had a complete recovery and was discharged on the twelfth postoperative day. Conclusions Left ventricular pseudoaneurysms are rare but potentially fatal. The symptoms revealing such complications are very diverse. Surgical treatment can be offered to younger patients.
