INTRODUCTION: The Cox Maze III procedure is considered the gold standard open surgical procedure for management of atrial fibrillation. This article outlines a unique case of a para-atrial mediastinal hematoma following a bilateral thoracoscopic left atrial Maze procedure mimicking malignancy. REPORT: A 60-year-old male, with past history of melanoma, underwent bilateral thoracoscopic left atrial mini maze procedure with radiofrequency energy and exclusion of the left atrial appendage...

Cardiac tumors presenting as mediastinal masses in childhood are rare. This report describes the case of a 6-year-old girl who presented to us after a failed attempt at resection of a mass arising from the left atrial appendage. Computed tomography-guided biopsy suggested a perivascular epithelioid cell tumor (PEComa). Sirolimus was started in order to reduce the mass size. She subsequently underwent resection of the mass by midline sternotomy approach and cardiopulmonary bypass. Recovery was uneventful and the child is doing well at two-year follow-up...

Differential diagnoses of mediastinal masses are often based on the anatomic locations. Traditionally the posterior mediastinum has been home to esophageal and neurogenic cysts, but a new entity has been found to be prevalent since its initial report in 2005: the Müllerian cyst. We present a 49-year-old with history of cough who was found to have such a mass. We will discuss the surgical outcome and the details of this interesting entity. The literature pertinent to this type of cyst will be evaluated. In all cases reported, the literature demonstrates that surgical removal results in uneventful follow-up with no evidence of malignancy or cyst recurrence...

BACKGROUND: Mediastinal thymic seminomas are rare male germ cell tumors with extragonadal origin that appear predominately with a cystic appearance. CASE PRESENTATION: A 22-year-old male was referred to our department for further investigation of a mediastinal mass discovered incidentally during routine chest X-ray. The patient has denied any symptoms including dyspnea, chest pain, cough, fever, dysphagia, hemoptysis, weight loss, and weakness. His past medical history was remarkable for orchitis, for which he had undergone a bilateral testicular biopsy, without the latter however, indicating the presence of a germ cell tumor or a premalignant lesion...

BACKGROUND: Nuclear protein in testis (NUT) midline carcinoma is a rarely diagnosed and potentially under-recognized type of squamous carcinoma that is considered one of the most aggressive human solid tumors. Alpha-fetoprotein elevation has been associated with chronic liver diseases and a limited number of cancers. In particular, in presence of a mediastinal mass in a young man, alpha-fetoprotein elevation is considered nearly pathognomonic of a non-seminoma germ-cell tumor. CASE PRESENTATION: A 22-year old man without any comorbidity was diagnosed with a large mediastinal mass with skeletal and lymph node metastases...

BACKGROUND: Castleman's disease is a rare lymphoproliferative disorder of unknown etiology that most commonly presents as a mediastinal nodal mass. It is exceptionally uncommon for Castleman's disease to present in the mesentery and, only 53 cases have ever been described in the literature. Standard treatment for this lymphoproliferative disorder involving a single node is a complete "en bloc" surgical resection which has proven to be a curative approach in almost all cases without recurrence after 20 years of follow up...

We describe a case of a 41-year old male patient with no significant prior medical history who presents with symptoms of Transient Ischemic Attack and stroke. Magnetic Resonance Imaging (MRI) of the brain identified areas of ischemia in the left side, and angiography showed occlusion of the left Medial Cerebral Artery (MCA). Cardiac Transthoracic Echocardiogram (TTE) for stroke evaluation incidentally noted a mediastinal abnormality leading to cancer work-up. Computer Tomography (CT) and (18) F-fluorodeoxyglucose (FDG) PET-CT scan of the chest incidentally revealed an avid 6 cm paraesophagial/subcarinal mass...

We describe the case of a patient successfully reconstructed with laparoscopic retrosternal gastric pull-up after esophagectomy for unresectable posterior mediastinal inflammatory myofibroblastic tumor, eroding into the esophagus and compressing the airways. A partial esophagectomy with esophagostomy was performed for treatment of esophageal pleural fistula and empyema, while the airways were managed with the placement of an endobronchial stent. Gastrointestinal reconstruction was performed using a laparoscopic approach to create a retrosternal tunnel for gastric conduit pull-up and cervical anastomosis...

Azygous Vein Aneurysm (AVAs) is an uncommon cause of mediastinal mass. They are typically asymptomatic and do not commonly require treatment. They may mimic mediastinal adenopathy on chest radiographs. We present a case of AVAs found during evaluation of chest pain in a patient who was also found to have pulmonary thromboembolism. The mass was worked up with cross-sectional imaging techniques using both Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) and ultimately Positron Emission Tomography (PET)...

Pulmonary Sclerosing Pneumocytoma (PSP) is a rare tumour of the lung and is always benign. Diagnosis is made incidentally following chest X-ray or chest CT scan performed for other clinical conditions. We report a case of PSP in a seven-year-old girl who got admitted for evaluation of an anterior mediastinal mass. Clinically, thought of teratoma or other germ cell tumour the mass was excised and sent for histopathological examination. Grossly, we received a pneumonectomy specimen measuring 13x11x8 cm with a nodular firm grey white lesion in the medial aspect of lower and middle lobe measuring 7...

Harlequin syndrome is a rare disorder of the sympathetic nervous system characterized by unilateral facial flushing and sweating. Although its etiology is unknown, this syndrome appears to be a dysfunction of the autonomic nervous system. To the best of our knowledge, thus far, very few reports on perioperative Harlequin syndrome after thoracic surgery have been published in the thoracic surgical literature. Here, we present the case of a 6-year-old patient who developed this unusual syndrome following the resection of a posterior mediastinal mass...

Background Posterior mediastinal lesions are classified as solid lesions and cysts. The treatment for both types is surgery. We evaluated the surgical outcomes and recurrence rates after video-assisted thoracic surgery and thoracotomy for posterior mediastinal lesions. Methods Data of 66 resections for posterior mediastinal masses between 2000 and 2014 were reviewed retrospectively. Twenty-two patients were treated by video-assisted thoracic surgery (group V) and 44 underwent thoracotomy (group T); 29 (43.9%) were female and 37 (56...

A 35-mo-old spayed female mixed-breed cat with continuous vomiting, emaciation, and abdominal distention for 2 wk was presented to a private veterinary clinic for evaluation. At 71 d after the initial visit, the cat died with anemia, jaundice, and hypoalbuminemia, and was subjected to autopsy. Grossly, numerous firm masses, 0.5-2.5 cm diameter, were randomly located in the left lobe of the pancreas. Histologic examination revealed that the pancreatic mass consisted of 2 tumor cell types: mostly small round cells with a minority of epithelial cells...

Chest wall resection and reconstruction for neoplastic diseases has unique oncologic, structural, and functional challenges. In a young and fit patient with a mediastinal mass and extensive anterior chest wall invasion, purely structural solutions were deemed insufficient. We hereby present a novel three-dimensionally printed patient-specific titanium implant of sternum and ribs. This osteointegrable implant was designed with biomechanical capabilities using a unique "Greek wave" folding pattern. Postoperative dynamic computed tomography showed that the implant allowed for controlled flexing during the respiratory cycle...

BACKGROUND: Atypical carcinoid arising from the mediastinal tissue is a rare neuroendocrine tumor and an association with parathyroid adenoma is very unusual. We report an unusual case of atypical carcinoid of mediastinum with metastasis in a patient presenting with parathyroid adenoma, which is the first case to be reported from Pakistan. CASE PRESENTATION: A 51-year-old Pakistani man was seen in postoperative intensive care after right parathyroidectomy and mediastinal mass resection for the management of postoperative hypocalcaemia...

The aim of this study is to evaluate the feasibility of percutaneous needle biopsy of mediastinal masses under conebeam computed tomography (CBCT) and "XperGuide" navigation guidance. From September 2013 to April 2016, 40 patients (25 men and 15 women; mean age 52.5 years; range 18.7-86.4 years) with 40 mediastinal masses underwent CBCT-/"XperGuide"-guided percutaneous needle biopsies. Technical success, sensibility, specificity, positive predictive value (ppv), negative predictive value (npv) and complications rate were evaluated...

Supot Puanglumyai, Suree Lekawanvijit
It is well-known that cardiovascular disease is the most common cause of sudden unexpected death, especially in the young. However complete postmortem investigation performed by qualified forensic pathologists is crucial in establishing the exact cause and manner of death. Sudden death caused by a cardiac tamponade occurring secondarily to a primary mediastinal tumor is extremely unusual. An autopsy on a 25-year-old man who died unexpectedly discovered a massive hemopericardium in association with an anterosuperior mediastinal mass...

In spite of difficult anatomic access for tumors of mediastinum, surgical resection remains the best diagnostic and therapeutic approach. Widespread acceptance of video-assisted thoracoscopy (VATS) is restricted by the limiting nature of instruments and suboptimal visualization. Robotic assisted minimally invasive surgery seems to hold most promise in remote, narrow anatomical regions. After obtaining approval from Institutional Review Board (IRB), a retrospective review of prospectively collected database on patients that underwent Robotic VATS between 2009 and 2013 was conducted...

Combination of sedatives such as fentanyl and midazolam during bronchoscopy is recommended by American College of Chest Physician due to its favourable drug profile. It improves patient comfort and tolerance, and is commonly given unless contraindicated. We describe a rare case of fentanyl-induced chest wall rigidity syndrome during a routine bronchoscopy with endobronchial ultrasound guided-transbronchial needle aspiration (EBUS-TBNA) in a 55 year old male presenting with a lung mass and mediastinal lymphadenopathy...
