Myxomas are the most common benign cardiac tumors and are located more frequently in the left atrium. In the literature there are cases describing the coexistence of thymic tumors and cardiac myxomas. In the case reported herein, during the resection of a cardiac myxoma, an enlarged thymus gland was encountered and resected. The histological exam revealed a thymic hyperplasia. The aim of this case study is to assess the need of conducting further studies in order to identify a common histological pathway between thymic lesions and cardiac myxomas...

Thymic epithelial neoplasms are malignant lesions that originate from the thymus and include thymoma, thymic carcinoma, and thymic neuroendocrine tumors. Although computed tomography (CT) is typically considered the imaging modality of choice for identifying thymic tumors, characterizing the primary neoplasm, and staging of disease, the role of magnetic resonance (MR) imaging continues to expand. MR imaging is effective in distinguishing thymic epithelial neoplasms and other malignant tumors from benign lesions in the prevascular mediastinum, can be used to characterize and stage thymic tumors in those patients with contraindications to contrast-enhanced CT, and can reveal morphologic features of thymic tumors...

Minimally invasive surgical techniques are important in surgical management of thymic pathologies. Traditional access techniques are being replaced with minimally invasive techniques using multiportal or uniportal approach. Adoption of minimally invasive techniques for thymic malignancies has been slow due to long term recurrence concerns. Recent studies show that minimally invasive video-assisted thoracoscopic surgery (VATS) or robotic approach to early stage thymic malignancies are associated with less intraoperative bleeding, lower rate of respiratory complications, shorter chest tube duration and shorter hospital stay...

OBJECTIVES: Bilateral vocal fold paralysis (VFP) is a severe complication after laryngotracheal (LT) surgery. The reduced glottic opening leads to significant respiratory distress immediately after the operation and requires the placement of a tracheostomy in most cases. Patients with a pre-existing unilateral VFP or expected recurrent nerve resection are at the highest risk for glottic failure. These patients might benefit from a pre-emptive glottic enlargement before LT surgery. METHODS: We performed a retrospective review of patients who received a pre-emptive glottis enlargement before LT surgery at the Medical University of Vienna from October 2011 to December 2016...

Radiologists in any practice setting should be prepared to use thoracic magnetic resonance (MR) imaging for noncardiac and nonangiographic applications. This begins with understanding the sequence building blocks that can be used to design effective thoracic MR imaging protocols. In most instances, the sequences used in thoracic MR imaging are adapted from protocols used elsewhere in the body. Some modifications, including the addition of electrocardiographic gating or respiratory triggering, may be necessary for certain applications...

Accurate imaging of the thymus is essential in the diagnosis and surgical treatment of both neoplastic and nonneoplastic conditions. Imaging of the thymus is a rather complex task, which affects both initial diagnosis and further surgical treatment planning. Imaging techniques include a wide armamentary of possibilities, from the most frequently used computed tomography (CT) to 18-fluorodeoxyglucose positron emission tomography- (18-FDG-PET-) CT and chemical shift magnetic resonance imaging (CS-MRI). In cases where surgical treatment is involved diagnostic imaging is of pivotal importance, not only in distinguishing benign from malignant disease but also in making a way among subtypes of thymic conditions...

Video-assisted thoracic surgery (VATS) for the management of non-thymomatous myasthenia gravis (MG) as well as the management of small thymomas and other benign thymic pathology has been gaining in acceptance and popularity as an alternative to the traditional median sternotomy approach. Although VATS thymectomy has been described in several variations, our current preference is a left sided VATS approach due to the exposure it provides in critical areas of dissection. Here we describe our technique for the left sided VATS thymectomy including patient selection, preoperative preparation, operative steps, and postoperative care...

REVIEW
M Jawad Latif, Bernard J Park
The use of robotic technology in general thoracic surgical practice continues to expand across various institutions and at this point many major common thoracic surgical procedures have been successfully performed by general thoracic surgeons using the robotic technology. These procedures include lung resections, excision of mediastinal masses, esophagectomy and reconstruction for malignant and benign esophageal pathologies. The success of robotic technology can be attributed to highly magnified 3-D visualization, dexterity afforded by 7 degrees of freedom that allow difficult dissections in narrow fields and the ease of reproducibility once the initial set up and instruments become familiar to the surgeon...

A 4-year-old girl who had been treated for asthma since the age of 2 years had a severe coughing fit and died suddenly. The patient had a history of occasional severe coughing fits, and these fits had been worsening in severity during the week before her death. Prior to death, she was taken to a clinician, and thymic hypertrophy was suspected based on chest X-ray findings. The clinician recommended that she visit a general hospital at a later date; however, she died that night. Postmortem radiology and autopsy revealed a large mass in the anterior mediastinum compressing the heart and airway, and no other findings attributable to sudden death were observed...

Ectopic hamartomatous thymoma (EHT) is a rare benign neoplasm of the lower neck suggesting branchial origin. Despite use of the term thymoma in the nomenclature, there is no evidence of thymic origin or differentiation. It affects middle-aged adults with a remarkable male predominance. To date less than 80 cases have been reported in the English literature. We present here two additional cases of EHT. The first is a benign case in a 31-year-old man, showing typical histological features. The second is a malignant case in a 70-year-old woman, showing intraductal carcinoma arising in intimate association with an EHT...

INTRODUCTION: The incidental early-stage thymic mass presents a diagnostic challenge. Video-assisted thoracoscopic (VAT) thymectomy is an attractive but potentially morbid solution. The aim was to show it can be safely applied as a first-line modality in those with undiagnosed thymic enlargement with acceptable long-term results. METHODS: A total of 45 patients were identified (24 male, median age 52 interquartile range [IQR]: 41-66 years) in a 14-year experience who had CT evidence of an enlarged, possibly malignant thymic mass, but no tissue diagnosis before undertaking VAT thymectomy...

OBJECTIVES: This study aimed to evaluate the role of pretreatment SUVmax and volumetric FDG positron emission tomography (PET) parameters in the differentiation between benign and malignant mediastinal tumors. In addition, we investigated whether pretreatment SUVmax and volumetric FDG-PET parameters could distinguish thymomas from thymic carcinomas, and low-risk from high-risk thymomas. METHODS: This study was conducted on 52 patients with mediastinal tumors undergoing FDG-PET/CT...

Dystrophic calcifications of the aortic valve may cause symptomatic aortic stenosis and account for a significant portion of patients who undergo elective valve replacement. Calcifications appearing grossly as a cloudy fluid surrounding the aortic valve leaflets are an uncommon finding. Normally, calcified aortic valves are characterised by large, nodular masses within the aortic cusps. We report a case of dystrophic calcifications on a stenotic aortic valve encountered intraoperatively, which was suggestive of infective endocarditis and abscess formation...

INTRODUCTION: Ectopic cervical thymus (ECT) is a rare embryological abnormality in children. It can be revealed by a compressive neck mass mistaken for a malignant tumor. Through a new case of ECT, we review the embryopathogenesis, diagnostic difficulties and therapeutic features. CLINICAL OBSERVATION: A 19-month-old girl presented a right cervical mass that quickly increased in size, causing intermittent dyspnea. The physical examination objectified a 6-cm, soft and compressible, painless right cervical tumefaction, extending from the mastoid area to the ipsilateral supraclavicular fossa...

During embryogenesis, the thymus and inferior parathyroid glands develop from the third pharyngeal pouch and migrate to their definite position. During this process, several anatomic variations may arise, with the thyroid being one of the most common sites of ectopic implantation for both organs. Here, we report the case of a young female patient, who underwent total thyroidectomy for papillary carcinoma of the thyroid. The patient's history was remarkable for disorders of the genitourinary system. Histologic examination revealed the presence of well-differentiated intrathyroidal thymic tissue, containing an inferior parathyroid gland...

BACKGROUND: The association between Graves' disease (GD) and thymic hyperplasia (TH) was first described in 1912 and has been reported numerous times thereafter. TH associated with GD presents as an incidental mediastinal mass on chest X-ray or computed tomography (CT). The pathogenesis of TH in the setting of GD is unclear but seems to involve a complex interplay of hormonal and immunological mechanisms. SUMMARY: Here, the effect that thyroid hormones and autoimmunity have on thymic growth and size is reviewed...
