1/52. Mediastinal bronchogenic cyst manifesting as a catastrophic myocardial infarction.Congenital bronchogenic cysts of the lung and mediastinum develop from the ventral foregut during embryogenesis. These cysts are often incidental radiologic findings in adults, but patients can be seen with symptoms of chest pain, cough, dyspnea, or any combination of these. Acute presentations are unusual and have rarely been reported. We present the unique case of a 36-year-old man seen with an acute coronary syndrome and sudden hemodynamic collapse. The patient sustained a massive and ultimately fatal myocardial infarction, compression of the left main coronary artery by a bronchogenic cyst was demonstrated at postmortem examination. If detected, bronchogenic cysts should be surgically excised to limit associated morbidity and mortality.- - - - - - - - - - ranking = 1keywords = bronchogenic cyst, bronchogenic, cyst (Clic here for more details about this article) |
2/52. Mediastinal parathyroid cyst: treatment with thoracoscopic surgery--a case report.Parathyroid cysts are rarely located in the mediastinum. This report describes a 45-year-old man with a mediastinal parathyroid cyst. Video-assisted thoracic surgery was successfully performed to remove the cyst.- - - - - - - - - - ranking = 0.0051192255364372keywords = cyst (Clic here for more details about this article) |
3/52. Primary mediastinal hydatid cyst.An unusual case of primary mediastinal echinococcosis in a young female presented with non-specific symptoms. On examination, she had signs of Horner's syndrome and mild superior vena cava compression. She was operated successfully. The final diagnosis could only be made on the operating table and confirmed by histopathology. Hydatid cyst in mediastinum is uncommon but because of surrounding vital structures and potential of its complete cure should be explored without delay.- - - - - - - - - - ranking = 0.0036565896688837keywords = cyst (Clic here for more details about this article) |
4/52. Bedside endosonography and endosonography-guided fine-needle aspiration in critically ill patients: a way out of the deadlock?endosonography and endosonography-guided fine-needle aspiration (EUS-FNA) are now established diagnostic techniques, which are performed electively in endoscopy suites. We report here the bedside use of EUS-FNA in three critically ill patients in an intensive-care unit, with a significant impact on the outcome. A mediastinal abscess after percutaneous dilational tracheotomy was aspirated in one patient, leading to appropriate antibiotic therapy and complete recovery. A paratracheal hematoma compressing the right main bronchus was aspirated in a patient with polytrauma, relieving the pressure effects. The third patient, who had end-stage dilated cardiomyopathy and was being evaluated for cardiac transplantation, was found to have an apical lung lesion suspicious for bronchogenic carcinoma. EUS was performed to exclude mediastinal metastasis and allow simultaneous resection at the time of transplantation. Although a metastasis was excluded by EUS-FNA, the patient died while awaiting surgery. We conclude that bedside EUS-FNA is a feasible procedure, and in experienced hands it can offer an alternative in life-threatening situations.- - - - - - - - - - ranking = 0.020593873663945keywords = bronchogenic (Clic here for more details about this article) |
5/52. A viable residual spinal hydatid cyst cured with albendazole. Case report.Spinal hydatid disease is a rare entity that frequently yields to severe, acute-onset neurological deficits. Although the gold standard treatment is total surgical removal of the cysts without inducing any spillage, it may not be possible to perform this in patients with multiple and fragile cysts. In such cases, the neural structures should be adequately decompressed and albendazole should be administered promptly. The authors describe the case of a 13-year-old girl who was admitted with a history of back pain and acute-onset lower-extremity weakness. magnetic resonance imaging scans demonstrated severe spinal cord compression caused by multiple cysts involving T-4 and the mediastinum. The patient underwent surgery, and the cysts were removed, except for one cyst that was hardly exposed. Following histopathological confirmation of spinal hydatid disease, she was treated with albendazole for 1 year. One year postoperatively, the residual cyst had gradually shrunk and had almost disappeared. Although a single case is not sufficiently promising, we believe that administration of albendazole is efficient to prevent recurrences in cases in which it is not possible to obtain total removal of the cysts without inducing spillage.- - - - - - - - - - ranking = 0.0080444972715442keywords = cyst (Clic here for more details about this article) |
6/52. Ectopic mediastinal pancreas.Ectopic localisation of the pancreas is not an uncommon entity, but it is mostly seen in the gastrointestinal tract. Herein we report a 45-year-old woman with a cyst containing pancreatic tissue in the mediastinum. The English literature reveals only three previous cases of this extremely rare localisation of the pancreas.- - - - - - - - - - ranking = 0.00073131793377675keywords = cyst (Clic here for more details about this article) |
7/52. Repeated unintentional transthoracic needle aspiration of a pulmonary hydatid cyst.Transthoracic needle aspiration is not a recommended diagnostic modality in hydatid disease. Percutaneous aspiration of a suspected hydatid cyst is believed to be associated with the risk of allergic reactions which can result in systemic anaphylaxis and possible spreading of the cyst contents. We present herein a illustrative case of pulmonary hydatid cyst and multiple mediastinal lymphadenopathies which was diagnosed after repeated transthoracic fine needle aspirations.- - - - - - - - - - ranking = 0.0051192255364372keywords = cyst (Clic here for more details about this article) |
8/52. Functional mediastinal parathyroid cyst: report of a case.We report herein a rare case of a functional mediastinal parathyroid cyst. A mediastinal tumor was detected by a chest x-ray film and subsequent computed tomography (CT) scan in a 68-year-old woman who was asymptomatic. Biochemical examination revealed that her serum calcium and intact-parathyroid hormone (i-PTH) levels were above the normal range. The findings of chest CT and magnetic resonance imaging suggested a cystic mass. The mass, which adhered tightly to its surrounding structures, was resected through a median sternotomy. The patient had an uneventful postoperative course, and her serum calcium and i-PTH levels rapidly returned to within the normal range.- - - - - - - - - - ranking = 0.0043879076026605keywords = cyst (Clic here for more details about this article) |
9/52. Ectopic cervical thymus: an uncommon diagnosis in the evaluation of pediatric neck masses.Ectopic cervical thymic tissue is an uncommon cause of neck masses in children, with fewer than 100 cases reported in children who presented with primary neck masses. To illustrate the unique characteristics of these tumors, we report the case of a 13-month-old boy with ectopic thymic tissue presenting with asymptomatic, bilateral, and solid cervical masses. This case report highlights several unique findings: (1) the rare nature of solid thymic tumors compared with cystic lesions, (2) the utility of magnetic resonance imaging scanning with and without fat suppression for diagnosis, and (3) the risks of surgical removal of thymic tissue in children. Despite its infrequent occurrence and often asymptomatic presentation, ectopic cervical thymus masses should be included as a rare cause of cervical masses in the pediatric population. awareness of this diagnosis will allow for appropriate preoperative diagnostic studies, which may preclude the need for biopsy.- - - - - - - - - - ranking = 0.00073131793377675keywords = cyst (Clic here for more details about this article) |
10/52. Thoracoscopic treatment of a pericardial diverticulum.A 35-year-old female patient presented with a history of recurrent chest pain. On chest x-ray, a regularly shaped lesion at the right cardiophrenic angle was observed. The lesion appeared smaller on a subsequent x-ray. magnetic resonance imaging showed a cystic lesion that could be differentiated from the pericardium only in its lower part. thoracoscopy revealed a pericardial diverticulum. Resection of the lesion was performed thoracoscopically, with complete remission of the symptoms.- - - - - - - - - - ranking = 0.00073131793377675keywords = cyst (Clic here for more details about this article) |
