Three-dimensional computed tomography-guided excision of an intrathoracic giant thymoma with elongated thymic vessels

We report the case of an intrathoracic giant thymoma with elongated thymic vessels, which was successfully resected under three-dimensional computed tomography guidance. A large, left-sided intrathoracic mass was incidentally found in a 41-year-old woman during a routine work-up for uterine cancer. Six vessels were noted arising from the tumor, five of which were connected to the anterosuperior mediastinum. The vasculature suggested that the tumor originated from the thymus and grew into the left pleural cavity, which pulled and elongated the associated vessels. Preoperative computed tomography imaging demonstrated that these vessels were located behind the tumor, which increased the risk for catastrophic intraoperative bleeding. We created a detailed surgical plan using our preoperative computed tomography data and successfully excised the tumor using intraoperative three-dimensional computed tomography guidance. Histopathological examination revealed a type AB thymoma without capsular invasion. This case highlighted the role of preoperative planning and intraoperative imaging in resecting an intrathoracic giant thymoma safely. In the video, we demonstrate how we performed the procedure under three-dimensional navigation.

3D Printed Template CT-Guided 125I Seed Implantation In The Treatment Of A Patient With Giant Type A Thymoma: A Case Report

Background: Thymoma, as a malignant tumor with low incidence, is still recommended to be treated with surgery. For middle and advanced patients who can not be treated with surgery, it is recommended to use preoperative radiochemotherapy or chemotherapy. After the tumor regressed, the feasibility of surgical resection will be evaluated. As a new technique developed in recent years, 3D template CT-guided 125I seed implantation has achieved effective results in the treatment of a variety of solid tumors. Case presentation: We report a case of locally advanced giant thymoma (more than 10 cm) who received 3D template CT-guided 125I seed implantation and achieved clinical complete remission. Conclusions: It suggested that radioactive particle implantation may be a new and effective method for the nonoperative treatments of thymoma.

Giant Thymoma with Benign Central Cystic Lesions in a 1-Year-Old Pug

ABSTRACT A 14 mo old pug was referred because of a large space occupying mass within the thoracic cavity. The patient was worked up with thoracic radiographs, cytology, and computed tomography. The most likely differential diagnosis was thymoma; therefore, a median sternotomy was performed, and the mass was bluntly dissected from the adjacent tissues. The patient recovered uneventfully from surgery and was discharged the next day. Histopathology diagnosed a thymoma with central cystic lesions. Thymomas usually occur in elderly patients and these patients are usually presented because of paraneoplastic signs. The age and signs at presentation, as well as the histopathologic appearance of the presented patient is quite atypical. According to telephone follow-ups, the patient was doing well 9 mo postoperatively.

Thymoma Presenting as a Giant Intrathoracic Mass

Thymoma is an epithelial neoplasm of the thymus, which commonly lies in the anterior mediastinum. Thymomas comprise about 1% of all mediastinal tumours. The current treatment of invasive thymoma is often multidisciplinary. This report presents a case of giant thymoma arising in the anterior mediastinum. Surgical resection was scheduled based on the radiological and fine needle aspiration cytology findings. The tumor was completely resected. The weight of the tumor was 2000g. The tumor was histologically diagnosed to type B1 thymoma. Patient was discharged from hospital with advice to attend the oncology department for next treatmentJ Bangladesh Coll Phys Surg 2016; 34(1): 37-41
