Bronchogenic cysts are rare congenital cystic lesions. Their occurrence in the anterior mediastinum as intrathymic bronchogenic cyst is extremely uncommon. These cysts present as mediastinal masses, and are generally asymptomatic and often diagnosed incidentally. Despite being benign, their intrathymic location and variable radiological appearance can mimic more common conditions such as thymomas. Surgical resection is the treatment of choice to confirm the diagnosis. We report a case involving a partial thymectomy performed for a suspected thymoma in the anterior mediastinum, which was subsequently identified on pathological examination as a bronchogenic cyst.

Mediastinal goiters represent descent of thyroid tissue from the neck to the intra thoracic cavity most commonly in the anterior mediastinal compartment. Posterior mediastinal extension is uncommon, comprising only 10-15% of all mediastinal goiters. Thyroid masses within mediastinum may present with range of symptoms from being asymptomatic to severe compressive symptoms according to size and location.

Background: Intercostal EV-ICD leads may work better inn contact with the pericardium thereby directing pacing and defibrillation energy toward excitable myocytes. We report three-month safety and performance outcomes with a second-generation intercostal EV-ICD lead paired with standard, commercially available ICD pulse generators (PGs).

Methods: Subjects undergoing a transvenous ICD (TV-ICD) procedure received a concomitant intercostal EV-ICD lead system.

In this report, we present a case of a 32-year-old female previously diagnosed with hereditary multiple exostoses(HME) who was incidentally found to have an asymptomatic anterior mediastinal mass during a routine examination. Computed tomography imaging revealed a well-defined mass measuring approximately 2.3 cm x 4.

Lung transplantation remains the only curative option for patients with end-stage, medically refractory respiratory failure. Traditionally, the clamshell incision has been the primary surgical approach, as it provides extensive access to the mediastinum and bilateral pleural cavities. However, it is also associated with notable drawbacks, such as an increased risk of sternal nonunion and wound complications, which can impede postoperative recovery.
