Neda Kalhor, Cesar A Moran
Sixteen cases of primary thymic adenocarcinoma are presented. The patients are 9 men and 7 women between the ages of 22 and 68 years (average: 45 years) who presented with non-specific symptoms including cough, chest pain, and dyspnea. Diagnostic imaging revealed the presence of an anterior mediastinal mass, which was surgically removed in all of the patients. Histologically, none of the tumors was encapsulated and showed different growth patterns including mucinous, non-mucinous, and papillary features. The majority of cases showed mixed growth pattern and the tumor was limited to the mediastinum with only a few cases extending to lymph nodes or pericardium...

Subcutaneous emphysema is a rare possible complication of dental procedures. The majority of the dental literature describes cases of localized areas of subcutaneous emphysema following various dental procedures, with a large number of these cases seen following intraoral surgical procedures. Classically, subcutaneous emphysema occurs within minutes to hours after conclusion of dental procedures and is commonly misdiagnosed as either an allergic reaction or acute post-operative swelling. This case report describes a four-year-old male who underwent dental rehabilitation for routine restorative dentistry without extractions under general anesthesia...

BACKGROUND: Heart-to-mediastinum ratios (HMRs) of 123I-metaiodobenzylguanidine (MIBG) have usually been applied to prognostic evaluations of heart failure and Lewy body disease. However, whether these ratios depend on patient age has not yet been clarified using normal databases. METHODS: We analyzed 62 patients (average age 57 ± 19 years, male 45%) derived from a normal database of the Japanese Society of Nuclear Medicine working group. The HMR was calculated from early (15 min) and delayed (3-4 h) anterior planar 123I-MIBG images...

Background: Mediastinum harbors a mixed bag of neoplastic lesions with varied therapeutic and prognostic implications. Distinguishing pulmonary squamous cell carcinoma from thymic carcinoma is a challenging task owing to rather nonspecific clinicoradiological features and a considerable overlap in histomorphological features. Thus, we evaluated the diagnostic utility of cluster of differentiation 5 (CD5) and CD117 immunohistochemical markers in distinguishing these tumors. Materials and Methods: The archives of department of histopathology were retrospectively reviewed from June 2012 to May 2016...

An aorto-cutaneous fistula is a rare complication that occurs after aortic surgery. Due to its rarity, postoperative complications are not normally highlighted in most standard teaching. We report here a case of aorto-cutaneous fistula after surgical treatment of a Stanford type A aortic dissection (AD) in a 67-year-old Chinese male. The patient presented with severe right heart dysfunction and a mass was found in the upper-middle of his chest, which started bleeding in the next years. On admission, preoperative aortic computed tomography angiography (CTA) showed a huge hematoma located in the anterior superior mediastinum and a shunt between the embedding cavity of the aortic root and right atrium...

Cervicothoracic junction can be approached anteriorly, anterolaterally, posterolaterally, and posteriorly. The anterior approaches in this region best address the ventral vertebral body disease but may cause significant morbidity. Twelve patients with their disease process located ventral to the spinal cord in the cervicothoracic junction underwent expansile manubriotomy and corpectomy. Eleven patients underwent fusion. One patient underwent an oblique corpectomy. All patients had their disease process from T1 to T3 vertebral levels...

Mediastinal lesions occur in a wide variety of clinical conditions. Metastatic granulosa cell tumour (GCT) in the mediastinum is a rare occurrence. We report a case of a woman who had a metastatic (GCT) in her mediastinum 40 years after treatment of the initial neoplasm. Surgical resection of the mediastinal mass revealed a low-grade epithelioid neoplasm with coffee bean-shaped nuclei and immunohistochemical stains that were consistent with metastatic GCT.

A 65-year-old man was diagnosed with granulomatosis with polyangiitis (GPA) at the age of 47, when cytoplasmic anti-neutrophil cytoplasmic antibody (C-ANCA) serology was positive, and he had multiple nodular shadows in both lungs. He had been treated with prednisolone, cyclophosphamide (CPA) and plasma exchange. At the age of 64, a nodular shadow was newly detected in the right lower lung field and serum tumour marker increased. Subsequent positron emission tomography/computed tomography scan demonstrated accumulations of fluorodexyglucose (FDG) in the same area, mediastinum lymph nodes, thoracic wall, right iliac bone, and right retroperitoneum...

A previously healthy 21-year old man presented to the emergency department with sudden onset central chest pain exacerbated by breathing. A plain chest X-ray showed air within the mediastinum and pericardium confirmed by a CT scan with contrast. The patient history did not raise suspicion of any concomitant disease and the diagnosis of spontaneous pneumomediastinum with pneumopericardium was made. The patient recovered completely over the next few days with bed rest and analgesics. Spontaneous pneumomediastinum is an uncommon disease caused by rupture of perivascular alveoli causing air leakage to the mediastinum...

BACKGROUND: Contrast esophagography often is performed to screen for anastomotic leakage (AL) after esophagectomy. However, its sensitivity remains low. Adverse events also have been reported. This report describes a new screening method to detect AL on computed tomography (CT) after esophagectomy. METHODS: From January 2012 to December 2015, 185 patients with esophageal cancer underwent surgical resection at the authors' institution. The study comparatively reviewed patient characteristics, surgical outcomes, and findings from postoperative CT images and contrast esophagrams of 142 patients who underwent esophagectomy followed by primary gastric conduit reconstruction through a posterior mediastinum route...

We herein report a case of one-stage laparoscopic surgery for extralobar pulmonary sequestration (EPS) and hiatal hernia. Our patient was a 2-year-old girl who was diagnosed as a mediastinal mass lesion. Postnatal computed tomography revealed that the mediastinal mass was an EPS. Two weeks after birth, the patient developed gastroesophageal reflux (GER), and esophagography showed a hiatal hernia. At 2 years of age, she underwent one-stage laparoscopic Nissen's fundoplication for GER with resection of the EPS in the posterior mediastinum...

Primary extraskeletal osteosarcoma (ESOS) presenting in thoracic locations is very rare and associated with a poor prognosis. The current study presents a case involving a large anterior mediastinal mass, which was histologically confirmed as a primary osteosarcoma. The literature concerning primary thoracic ESOS is reviewed. A total of 60 cases were identified. The median age was 60 years (range, 14-93 years) and males were more prevalent among the reported cases (65%). Survival analysis revealed that the overall 5-year survival was only 22...

NUT (nuclear protein in testis) midline carcinoma is a rare malignant tumor arising in midline structures, such as head, neck and mediastinum. In the 2015 WHO classification of lung tumours, it was categorized in "Epithelial tumors". However, because of limited clinical data, its biological features have not been fully recognized. We report a case of NUT midline carcinoma presented as a primary lung tumor. Pneumonectomy was performed without any neoadjuvant therapy and it turned out to be a gross total resection...

Background: The posterior mediastinum is the preferred location for reconstruction following esophagectomy. Occasionally alternative routes are required. We examined patient outcomes of esophageal reconstruction in order to determine whether substernal reconstruction (SR) is an equivalent alternative to orthotopic placement. Methods: Following IRB approval, we performed a retrospective review of all patients who underwent an esophagectomy from 1988-2014. Only patients reconstructed with a gastric conduit and cervical anastomosis by either substernal or posterior mediastinal (PM) routes were included in the study...

Streptococcus intermedius is a Gram-positive commensal of the oral cavity with tendency to cause brain and liver abscesses. Mediastinal involvement from S. intermedius is very rare. We present a case of 22-year-old male with newly detected mediastinal conglomerate nodal mass. On his way for bronchoscopy, he developed seizures and was found to have three brain lesions. The aspirate from brain biopsy grew S. intermedius whereas the aspirate from mediastinum showed only acute inflammation. Follow up imaging after antibiotic treatment showed interval resolution of brain abscesses and the mediastinal mass...

Kikuchi-Fujimoto disease (KFD) is a histiocytic necrotising lymphadenitis characterised by painful cervical lymphadenopathy, fever, malaise and weight loss. Infections, auto-immune pathogenesis and a genetic association have been implicated. A 12-year-old boy presented with a 1-month history of fever, abdominal pain, constipation and weight loss, and a painful lymph node was detected in the right axilla. Chest CT demonstrated multiple lymph nodes, especially in the left mediastinum. Salmonella enteritidis group D was detected in a blood culture and he was treated with ceftriaxone, followed by meropenem...

OBJECTIVES: The seminal phase II trial for pulmonary stereotactic body radiation therapy (SBRT) suggested that SBRT to central lesions resulted in unacceptable toxicity. Alternative dose-fractionation schemes have been proposed which may improve safety without compromise of efficacy. We report our institutional outcomes of SBRT for hilar/mediastinal non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: A retrospective review was conducted of patients with NSCLC in a hilar or mediastinal nodal station which was treated with SBRT...
