Although there are several reports of intracranial hemorrhage associated with vitamin K deficient bleeding, there are few reported cases of extracranial manifestations, specifically involving the thymus. Here, we discuss the unique case of a 4-week-old infant presenting with scrotal discoloration, respiratory distress, and widened mediastinum, found to have thymic hemorrhage related to confirmed coagulopathy secondary to late-onset vitamin K deficiency bleeding of the newborn.

We present the case of a severe familial primary hyperparathyroidism related to a germline deletion in the HRPT2 (CDC73) gene. Morphological explorations revealed 2 potential hyperfunctioning parathyroid glands: a left cervical lesion on the neck ultrasound, and an ectopic mediastinal lesion on the parathyroid scintigraphy using Tc-methoxyisobutylisonitrile and on F-fluorocholine PET/CT. Surgery removal and histopathological examination determined that the mediastinal mass corresponded to a thymoma and the cervical lesion to a parathyroid adenoma...

A 10-year-old female Australian Cattle Dog was referred for investigation of a mediastinal mass. During clinical examination, a mandarin- sized mass was detected ventrally of the trachea. According to computed tomographic (CT) findings and cytology of a fine-needle aspirate, thyroid neoplasia was suspected. The assumed tumour affected the left thyroid gland and was staged as stadium II because of enlargement of the ipsilateral cervical and retropharyngeal lymph nodes. The left thyroid, including the parathyroid gland, was removed surgically with a guarded prognosis...

Neurogenic tumours of the mediastinum in adults occur most often at the posterior mediastinum, majority of which are benign of nerve sheath in origin. A 72-year-old woman, known asthmatic, presented with chronic symptoms of hoarseness, dysphagia, chest heaviness, easy fatigability, cough, epigastric pain, feeling of abdominal fullness and choking with food intake and at a supine position. Treated for other disorders, routine chest X-ray incidentally found a homogenous convex radiodensity at the right paratracheal area; mass which was also observed with CT and 18F-fludeoxyglucose-positron emission tomography/CT scan studies...

BACKGROUND: Surgical resection is the main treatment for patients with non-small-cell lung cancer (NSCLC), but patients' long-term outcome is still challenging. The purpose of this study was to identify predictors of long-term survival in patients after lung cancer surgery. METHODS: Patients who underwent surgery for NSCLC from January 1, 2006, to December 31, 2009, were enrolled into this retrospective cohort study. The primary outcome was the survival length after surgery...

BACKGROUND: Germ cell tumors (GCTs) in children are rare neoplasms with diverse pathological findings according to the site and age of presentation. The most common symptoms in children with mediastinal GCTs, which are nonspecific, are dyspnea, chest pain, cough, hemoptysis, vena cava occlusion syndrome, and fatigue/weakness. Because of these nonspecific symptoms, it is difficult to suspect a mediastinal mass. A posterior mediastinal tumor causing spinal cord compression is an important example of an oncologic emergency arising from a neurogenic tumor...

Background: Solitary fibrous tumor of the pleura (SFTP) arising from the mediastinal pleura may be confused with primary mediastinal tumors. We studied the computerized tomographic (CT) findings of patients with SFTP that could suggest a diagnosis of SFTP. Materials and Methods: At our hospital from January 1995 to June 2012, 39 patients with histologically confirmed SFTP were surgically treated; seven of them abutting the mediastinal pleura. The study group included seven patients aged between 53 and 81 years...

PURPOSE: To perform a systematic review of the effect of blood glucose levels on 2-Deoxy-2-[18F]fluoro-D-glucose (18F-FDG) uptake in normal organs. METHODS: We searched the MEDLINE, EMBASE and Cochrane databases through 22 April 2017 to identify all relevant studies using the keywords "PET/CT" (positron emission tomography/computed tomography), "standardized uptake value" (SUV), "glycemia," and "normal." Analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations...

A 43-year-old woman presented with an FDG-avid mediastinal Ewing sarcoma invading and nearly occluding the superior vena cava. Geographic increased FDG uptake in hepatic segment IVA was the only other site of nonphysiologic FDG activity. This focal activity was without an underlying mass, had atypical morphology for a hepatic metastasis, and correlated well with prior CT findings of abnormal segment IVA enhancement resulting from the recruitment of portocaval collaterals. In the correct setting, the F-FDG hepatic hot spot should be considered in the differential of a focal FDG-avid hepatic lesion in segment IVA...

Diagnosing endobronchial tuberculosis (EBTB) can be difficult due to the lack of specific signs and symptoms that differentiate it from other respiratory diseases, such as lung tumors. We hereby report a case of a very rare presentation of tuberculosis (TB) in a patient who presented with a dry cough and significant weight loss for 3 months. Chest X-ray and CT scan of the chest showed partial atelectasis and a segmental collapse of the right upper lobe and tumor-like arising from its bronchus along with a large right para-tracheal mediastinal lymphadenopathy, mimicking a metastatic (N2) disease...

OBJECTIVE: Preoperative chest radiograph screening is widely used before cardiac surgery. The objective of this study was to investigate the frequency of abnormal findings on a routine chest radiograph before cardiac surgery. METHODS: In this retrospective cohort study, 1136 patients were included. Patients were scheduled for cardiac surgery and underwent a preoperative chest radiograph. The primary outcome was the frequency of abnormalities on the chest radiograph...

Intrathoracic kidney is a partial or complete displacement of the kidney above the hemidiaphragm into the mediastinal compartment of the thorax. It is usually seen as an incidental finding discovered on chest radiograph or abdominal ultrasound. However computed tomography consents the correct detection of intrathoracic masses and defines their shape, size, and extent. We here report a case of ectopic thoracic kidney in a 22-year-old man who had a long history of scrotal discomfort associated with right varicocele...

We report a case of acute pancreatitis secondary to pancreatic neuroendocrine tumor. A 46-year old man presented with upper abdominal pain. The serum amylase and lipase were elevated. Abdominal computed tomography (CT) and magnetic resonance cholangiopancreatography revealed a 1.7 cm sized mass at the pancreas body with a dilatation of the upstream pancreatic duct and mild infiltrations of peripancreatic fat. An endoscopic ultrasound-guided fine needle biopsy was performed for the pancreatic mass, but only necrotic tissue was observed on the pathologic examination...

Background: Postoperative bleeding is a common problem in cardiac surgery. We tried to evaluate the effect of topical tranexamic acid (TA) on reducing postoperative bleeding of patients undergoing on-pump coronary artery bypass graft (CABG) surgery. Materials and Methods: One hundred and twenty-six isolated primary CABG patients were included in this clinical trial. They were divided blindly into two groups; Group 1, patients receiving 1 g TA diluted in 100 ml normal saline poured into mediastinal cavity before closing the chest and Group 2, patients receiving 100 ml normal saline at the end of operation...

Extramedullary hematopoiesis (EMH) is a rare disorder, defined as the appearance of hematopoietic elements outside the bone marrow or peripheral blood. The most common sites of EMH are liver and spleen, but it has been documented in other organs such as the mediastinum, lymph nodes, breast, and central nervous system. EMH occurs as a compensatory mechanism for bone marrow dysfunction in severe thalassemia. We report a case of EMH presenting as a posterior mediastinal mass in a 34-year-old woman with thalassemia intermedia with chronic cough and shortness of breath on exertion...

Mediastinal tumors are heterogeneous and the diagnosis depends on their location in the mediastinum. The most frequent tumors are germinal tumor, lymphoma and thymoma. The clinical and radiological aspects are often not sufficient to orient the diagnosis and biopsy is necessary to confirmed it. Here, we present a rare case of an anterior mediastinal mass incidentally detected in a 63 years old man during assessment for asthma. The lesion was presumptively diagnosed as a thymic epithelial tumor based on location and radiological characteristics...
