2024年7月31日 · Neurogenic tumors are the cause of approximately 90% of posterior mediastinal masses. They can be subdivided into three groups by their location and involvement of peripheral nerves or sympathetic chain 1-3.

Neurogenic tumors are commonly found in the posterior mediastinum, also known as paravertebral, the back of the spine. In most adults, neurogenic tumors do not cause noticeable symptoms and are usually detected on routine chest X-rays or, incidentally, on an MRI or CT scan done for other reasons.

The gold standard in the treatment of benign neurogenic tumors is surgery to achieve complete resection of the tumor. The standard posterolateral thoracotomy is the most used approach. However, in order to preserve the integrity of the respiratory muscles, to minimize postoperative pain, and depending on the location of the tumor; posterior or ...

Neurogenic tumors represent a broad ill-defined category of neoplasms that includes tumors of Schwann cell and/or neuroblastic derivation, as well as neoplasms that typically develop in the central nervous system, but rarely present in ectopic sites including the mediastinum.

2016年1月10日 · Although a large number of primary lesions may occur in the spinal cord, nerve roots, dura, and osseous spine, most lesions within the spine are metastatic tumors. 7 Such lesions occur primarily in the extradural compartment, especially in the osseous structures.

2012年11月20日 · MRI findings reflect pathologic features of mediastinal neurogenic tumors. Integrating consideration of age and clinical findings of the patient, lesion location, and imaging findings is important in the diagnosis of mediastinal neurogenic tumors.

Neurogenic tumors appear radiographically as a unilateral paravertebral mass.6,141,142 Clinical manifestations include chest pain from nerve or bone erosion, dyspnea secondary to tracheal compression, and neurologic deficits resulting from spinal cord compression by …

Neurogenic tumors are the most common dumbbell tumors. These tumors may grow within the spinal canal and neural foramen and compress the spinal cord and nerve root of origin. In addition, the tumors may expand outside the spinal canal. As the paraspinal portion of a tumor enlarges, it can adhere to and compress adjacent structures.

2022年5月25日 · Methods: A retrospective analysis of 26 patients with neurogenic turors of the sacral spine who were surgically treated from January 2001 to January 2018, including 16 males and 10 females, aged from 21 to 69 years old with an average age of (39.3±10.9) years old. The courses of diseases ranged from 3 to 56 months with an average of (17.9±10. ...

Benign neurogenic tumors are usually discovered as an incidental finding on cross-sectional imaging. A thorough history and physical examination should focus on neurologic compressive symptoms depending on the location of the tumor such as pain, paresthesia, or weakness.
