Article Abstract
We studied 13 patients with mediastinal abscesses caused by oropharyngeal infections, who presented between April 2007 and June 2011. All patients were operated on after maxillofacial and ear, nose and throat surgeons had treated the primary source and drained all collections in the neck. Thoracic surgery was performed in the same session. Anterior mediastinal collections were drained via a small mediastinotomy. Posterior collections were approached via a thoracotomy. Chest computed tomography was essential to delineate the extent of disease. A thoracotomy approach was used in 7 patients; 2 of them required an anterior mediastinotomy on the opposite side. The others had an anterior mediastinotomy which was bilateral in 2 cases. After repeat computed tomography, 5 patients were operated on for suspected new loculations; tissue edema had caused false imaging in 3 of them. There was no mortality. Early after eradication of the source and pathways to the mediastinum, gravity drainage of mediastinal abscesses, and good antibiotic cover, with repeat computed tomography after 3 days, was an effective approach in this highly fatal disease.

Introduction: Solitary plasmacytomas are tumors characterized by a local increase of malignant plasma cells in soft tissue or bone and may occur anywhere without evidence of systemic disease. The aim was to focus on the main surgical techniques and outcomes for this rare chest wall tumor.
Methods: Patients with solitary plasmacytoma involving a rib, who were operated for diagnostic or treatment purposes between 2018 and 2023 were retrospectively reviewed.

Background: Communicating vessels among hepatic veins in patients with tumors invading/compressing hepatic veins at their caval confluence facilitate new surgical solutions. Although their recognition by intraoperative ultrasound has been described, the possibility of preoperative detection still remains uncertain. We aimed to develop a model to predict their presence before surgery.

Traumatic injury remains a leading cause of death worldwide, with traumatic bleeding being one of its most critical and fatal consequences. The use of whole-body computed tomography (WBCT) in trauma management has rapidly expanded. However, interpreting WBCT images within the limited time available before treatment is particularly challenging for acute care physicians.

Rationale: Traumatic pseudoaneurysm of the sinus of Valsalva (PSV) is a rare but life-threatening condition, often resulting from blunt chest trauma. Rapid progress and a high risk of rupture highlight the importance of prompt diagnosis and intervention. We present a case of a rare pseudoaneurysm linked to the right coronary sinus after blunt chest trauma.

Rationale: Thrombus is the most common occupying lesion in the cardiac chambers, it is often distinguished from cardiac neoplastic occupations. Among them, the most common is cardiac myxoma, whose imaging manifestations are often confused with thrombus. However, the 2 types of lesions have different therapeutic strategies and are both potentially high-risk sources of embolism, so early differentiation between intracardiac thrombus and cardiac tumor is essential.
