1/10. Thymic cyst: is a correct preoperative diagnosis possible? Report of a case and review of the literature.A case of a giant cervico-mediastinal cyst of thymic origin in an 8-year-old child is presented. The cyst was asymptomatic except for deformity due to its size. In spite of several diagnostic approaches like ultrasonography, computed tomography, cyst puncture with biochemical analysis of cyst content and direct contrast injection and radiography after emptying of the cyst, the ultimate diagnosis as to the origin of the cyst was not disclosed until after operation and histopathological examination of the operative specimen. On a more general basis the diagnostic possibilities and pitfalls are discussed. Conclusion: a correct preoperative diagnosis of a thymus cyst is difficult and in many instances impossible even when all diagnostic measures at hand are utilized, including radiographic methods, computed tomography, magnetic resonance imaging, ultrasonography and biochemical examination of cyst aspirate and estimation of tumour markers in cyst fluid and serum.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/10. Giant dumbbell-shaped gastroenteric cyst presenting with total situs inversus.We present a case of an 8-month-old boy with total situs inversus, who had a giant dumbbell-shaped gastroenteric cyst. The concurrence of these entities has never been reported previously. The cyst occupied a large space in the mediastinum and involved both hemithoraces.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
3/10. Displacement of the heart by a giant mediastinal cyst.A giant mediastinal cyst caused marked cardiac displacement, factitious cardiomegaly and clinical and hemodynamic findings suggestive of constrictive pericarditis. The correct diagnosis was established with echocardiography and confirmed with angiography and surgery.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
4/10. Giant transdiaphragmatic duodenal duplication with an intraspinal neurenteric cyst as part of the split notochord syndrome: report of a case.We report the case of a 6-month-old girl with a giant transdiaphragmatic duodenal duplication connecting to a cervical intraspinal cyst, which compressed the heart and lung, causing severe respiratory distress. We removed the intraspinal neurenteric cyst through a posterior cervical incision at the C6 and C7 level, and the duodenal duplication cyst in the mediastinum was removed through a right thoracotomy. Her respiratory symptoms were completely resolved by these operations.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
5/10. Videoscopic resection of a giant symptomatic pericardial cyst: case report.A 47-year-old woman presented with shortness of breath, chest discomfort, and hoarseness. She was found to have an enlarged cardiac silhouette on plain chest radiography. Computed tomographic scan and magnetic resonance imaging were diagnostic of a giant pericardial cyst. The patient underwent successful videoscopic removal of the cyst with complete resolution of her symptoms.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |

7/10. Respiratory complications in cervical thymic cysts.Thymic cysts are considered uncommon lesions in the differential diagnosis of pediatric neck masses. They have been described as asymptomatic and of little clinical consequence. Recent reports have stressed the possibility of respiratory compromise associated with these lesions. We reviewed our experience with cervical thymic cysts with emphasis on respiratory problems. Ten pediatric patients underwent surgery and were found to have cervical thymic cysts. Ages ranged from newborn to 14 years. There were four boys and six girls. Two were found to have the thymic cysts at time of neck exploration for Grave's disease and hyperparathyroidism. Of the remaining eight patients, all had mobile cystic masses, located anterior to but extending beneath the lower third of the sternocleidomastoid muscle. The size of the mass ranged from 3.0 to 8.5 cm. Preoperative diagnosis included cystic hygroma/branchial cleft cyst (five), lymphoma (one), teratoma (one), and thymic cyst (one). All had a history of rapidly developing neck mass. Seven of the eight gave a history of upper respiratory tract infection (URI) prior to the development of the mass. Five had imaging studies that showed tracheal compression. Three of these required airway management in the early postoperative period. All were excised through a neck incision, with two requiring sternal extension. histology showed cholesterol crystals, Hassall's corpuscles, and giant cell reaction diagnosis of thymic cysts. There has been no recurrence and no permanent respiratory sequela in the ten patients. Cervical thymic cysts are benign lesions that may be more common than literature suggests.(ABSTRACT TRUNCATED AT 250 WORDS)- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
8/10. Thoracoscopic drainage and resection of giant mediastinal cyst.Video thoracoscopy is being used with increasing frequency by thoracic surgeons. Although initially used primarily for simple diagnostic purposes, improved instrumentation and evolving expertise have allowed for the performance of increasingly complex therapeutic procedures. We present a case of a giant subcarinal bronchogenic cyst in an elderly man with multiple medical problems. The cyst nearly occluded the bronchus intermedius and resulted in recurrent respiratory tract infections. Using video thoracoscopy, the cyst was drained and the wall of the cyst was resected successfully with minimal concomitant morbidity.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
9/10. Giant mediastinal parathyroid cyst: an unusual cause of hypercalcemic crisis--case report and review of the literature.BACKGROUND: cysts of the parathyroid gland located in the mediastinum are rare but well-defined clinical and pathologic entities. Since the first case report in 1925 a total of 28 mediastinal parathyroid cysts have been reported. methods AND RESULTS: An 83-year-old woman with acute hypercalcemic crisis is reported. The patient had a giant mediastinal parathyroid cyst. Her symptoms resolved completely after the cystic tumor was resected. The case is discussed, and the world literature is reviewed. CONCLUSIONS: Hypercalcemic crisis is a rare but potentially fatal complication of hyperparathyroidism. Resection of the parathyroid tumor results in prompt recovery. A thorough bilateral neck exploration should be performed after the patient's condition is stabilized. Mediastinal exploration is indicated at the initial operation, if a parathyroid tumor is not present in the neck or is not accessible through a cervical incision. Localization studies can be done before the operation in patients with hyperparathyroid crisis, but the results of localization studies should not preclude a thorough surgical exploration.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
10/10. ethanol sclerosis: one of the best treatments for thymic cyst in very elderly patients?An 83-year-old female patient with a giant thymic cyst that was successfully treated by percutaneous aspiration and ethanol injection. The patient had complained of coughing and chest discomfort for several years. A chest x-ray film revealed the shadow of a large abnormal mass in the anterior mediastinum. We diagnosed it as a thymic cyst. The patient refused surgery because of her age. We chose a less invasive therapy, namely, ethanol sclerosis of the cyst. The cyst was successfully treated without any complications, and no recurrence was found at the one-year follow-up. This therapy may be one of the best treatments for thymic cysts, especially in very elderly patients.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
