1/15. Excision of cervical cystic lymphangioma using injection of hydrocolloid dental impression material. A technical case report.A lymphangioma, arising in an adult patient, was completely removed after injection of hydrocolloid dental impression material. The postoperative course was uneventful, with no sign of foreign-body reaction. The agar impression material, which had excellent tractability during operation, may be used as a filling material, as long as preoperative examinations show that the tumor does not involve major vessels or nerves.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/15. Echo-enhancing sonography of a large-vessel hemangioma of the neck.Because of the slow flow in the venous spaces of large-vessel hemangiomas, demonstration of color flow signals with conventional color Doppler or power Doppler sonography may be difficult. We report the case of a 22-year-old female patient with a soft tissue tumor containing multiple fluid-filled spaces in the right supraclavicular region. Gray-scale, color, and power Doppler sonography could not differentiate between cystic lymphangioma and large-vessel hemangioma. The intravenous echo-enhancing contrast agent Levovist was administered, and a significant echo-enhancing effect on color and power Doppler imaging was demonstrated in the fluid-filled spaces and lasted for about 3 minutes. Histopathologic study of the excised tumor confirmed the sonographic diagnosis of hemangioma. Levovist appears useful in depicting slow flow in a large-vessel hemangioma.- - - - - - - - - - ranking = 7keywords = vessel (Clic here for more details about this article) |
3/15. Cystic hygroma of the skull base.Cystic hygroma is a benign developmental tumor formed by lymph vessels that occurs in 1 of 12000 individuals and presents most frequently in the head and neck. It is often difficult to manage because the tumor frequently envelopes nearby vital structures. Lesions that extend significantly above the hyoid are especially difficult to excise because of the complexity of achieving a complete excision. This article describes a series of 3 cases of cystic hygroma that presented in the head and neck and, on further investigation, were found to also involve the skull base. This anatomic location is exceedingly rare, and these 3 cases represent new and difficult challenges not previously discussed in the literature, to our knowledge.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/15. lymphangioma of the lesser omentum associated with abdominal esophageal carcinoma: report of a case.A case of lymphangioma of the lesser omentum associated with abdominal esophageal carcinoma is described herein. The patient was a 54-year-old man who initially presented with dysphagia. Gastrointestinal fiberscopy (GIF) revealed an esophageal carcinoma and abdominal computed tomography (CT) detected a 3-cm, low-density lesion on the median aspect of the fornix, which was diagnosed as a metastatic lymph node. A radical operation was performed to resect the esophageal carcinoma, and a cystic lesion the size of a hen's egg was found in the lesser omentum of the stomach. The cystic lesion, which contained serous fluid, was unilocular and attached to the serosa of the stomach. The histological diagnosis was omental lymphangioma. Our review of the Japanese literature revealed 29 cases of lesser omental lymphangioma, but only two of these were associated with an advanced malignant tumor. Although the etiology of omental lymphangioma is unclear, the findings in our case suggested that obstruction of the lymphatic vessels invaded by the esophageal carcinoma may be one of the causes of this disease.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/15. Thoracic cystic lymphangioma (cystic hygroma): a chest pain syndrome--a case report.vascular malformations of the mediastinum including mediastinal lymphangioma are exceedingly rare in adults. A resected case of mediastinal cystic lymphangioma (cystic hygroma) that presented with acute onset of retrosternal chest pain is reported in a 45-year-old man. Cystic hygromas are benign cysts frequently discovered incidentally on chest radiograph. Although computed tomography scan provides helpful information about the size, density, and site of the cysts, it cannot establish a precise diagnosis concerning its nature. Complete removal of the cyst is the treatment of choice and allows precise diagnosis on histologic examination. However, surgical excision is sometimes difficult, owing to the size and extension of the cysts, infiltrating mediastinal planes, enveloping great vessels, and displacing mediastinal organs without invasion. The difficulty of completely eradicating certain cysts explains cases of insidious progression with compressive recurrence. The subject is succinctly reviewed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/15. Prenatal dna diagnosis of noonan syndrome in a fetus with massive hygroma colli, pleural effusion and ascites.Prenatal molecular genetic diagnosis for noonan syndrome I is reported. noonan syndrome was suspected because of large cystic hygroma colli, massive pleural effusion and ascites at 23 weeks of gestation and normal karyotype (46,XX). dna was prepared from amnion cells and screened for mutations in the PTPN11 gene. In exon 8, a missense mutation (S285F) was found. Delivery was induced at 33 weeks of gestation because of silent cardiotocography (CTG).Despite immediate drainage of the hydrothorax, mechanical ventilation was insufficient and the child died 9 h after birth due to severe pulmonary hypoplasia. Pleural punctate was enriched for small lymphocytes and thus was characterized as chylus.Prenatal ultrasound findings in noonan syndrome usually are unspecific and rarely lead to a diagnosis. However, with the combination of cystic hygroma, pleural effusion, ascites and normal karyotype noonan syndrome should be considered and dna testing for PTPN11 mutations may be appropriate. Malformations of lymphatic vessels and/or chylothorax in noonan syndrome seem to be more frequent than usually anticipated.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/15. Mediastinal cystic lymphangioma: is resection always necessary?Mediastinal cystic lymphangiomas are rare tumours. Usually asymptomatic, they can be complicated by a chylopericardium or/and chylothorax. We report a case of a left lesion infiltrating through the supra-aortic vessels complicated with a iatrogenic left chylothorax managed by bilateral video-assisted thoracoscopy at the same time. First, on the right, the chylous inflow was stopped by suturing the thoracic duct; then, on the left, a fenestration was done to confirm the diagnosis and treat the lesion while preserving the adjacent structures.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/15. OK432 (picibanil) efficacy in an adult with cystic cervical lymphangioma. A case report.Cervical cystic lymphangioma (CCL) is a rare and benign tumour involving congenital and cystic abnormalities derived from lymphatic vessels. The most accepted treatment continues to be surgical excision. However, when this infiltrates vital neurovascular neck structures, complete excision is difficult and if only partial, the recurrence rate is very high. The most frequently used alternative treatment is to inject sclerosants into the lesion. The use of these techniques has reported good results in children; however, there are few references thereof with regard to adults. We are reporting on a cervical cystic lymphangioma in a male aged 22, treated with an intra-lesion injection of 20 cc with 0.01 mg/cc dilution of OK-432 (picibanil) in physiological serum. Sole complications were fever and local reaction where the solution was injected. One month after treatment the lymphangioma had totally remitted and sixteen months later continues in remittance.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/15. Cystic lymphangioma of the right adrenal gland.Lymphangiomas are benign malformations of the vessels. They are commonly located in the neck, axillary region and mediastinum. lymphangioma of the adrenal gland is very rare. These lesions were first discovered as incidental autopsy findings. As the imaging techniques have improved, they now appear as incidental findings at abdominal ultrasonography and computed tomography scan examinations. They are usually asymptomatic. We present a 26-year-old woman admitted to the hospital, complaining of weakness, putting on weight, and lumbago. Her laboratory findings were within normal limits. Radiological examination revealed a 7 cm cystic lesion located in the right adrenal gland. Right adrenalectomy was performed. Histopathological examination and immunohistochemical analysis of the cystic lesion was consistent with a lymphangioma.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/15. Cystic hygroma of the breast: a rare lesion.Lymphangiomas are congenital malformations of lymphatic vessels. More than 50% of these lesions are present at birth; 90% are diagnosed by the age of 2. These lesions do not expand very rapidly but they tend to infiltrate surrounding tissues; their degeneration into malignant tumors is an extremely rare occurrence. They are mostly located in the neck region and the axilla; breast lymphangioma is very rare. Surgery is usually performed for aesthetic reasons and in order to make a differential diagnosis with other, more common lesions. The surgical procedure involves the excision of the mass; other methods, such as radiotherapy and sclerotherapy, have proved to be completely ineffective.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
