The natural history of asymptomatic retroperitoneal schwannomas is poorly understood. This study aimed at investigating the natural history of incidental retroperitoneal schwannomas. The medical charts and imaging studies of 22 asymptomatic patients under observation for at least 12 months for retroperitoneal schwannomas were reviewed. The duration of follow-up ranged between 13 and 176 months (mean 48 months). In the 22 patients managed by the "wait and see" approach, the average tumor size at initial presentation was 51 mm, which increased to 57 mm at final follow-up. During the final follow-up, 2 patients required surgical treatment for tumor enlargement, while the remaining patients remained asymptomatic without surgery. The average growth rate of the tumors was 1.9 mm/year (range: -1.9 to 8.7 mm/year). The majority of asymptomatic retroperitoneal schwannomas demonstrate minimal growth and may be suitable for management with the "wait and see" approach.

Retroperitoneal sarcoma (RPS) is a rare disease, and until recently, its natural history and outcome were poorly understood. Recently, collaborations between individual centers have led to an unpreced...
Schwannomas of the hypoglossal nerve are rare and account for a very small percentage of non-vestibular schwannomas.
The current study investigated the role of radiotherapy (RT) in patients with primary nonmetastatic retroperitoneal liposarcomas.
The differential diagnosis and therapy of retroperitoneal masses suspicious for soft tissue tumors remains difficult and needs individual decisions as to the best management of patients. We report an ...
Anterior retroperitoneal spinal exposures are widely used today for spinal surgeries. Incisional hernias are a documented complication of anterior spine exposures; however, there are no documented cas...
Schwannomas are benign tumors that can reach giant sizes. The diagnosis and treatment of these cases differ from those of small schwannomas. The aim of this study was to review the diagnos...
To elucidate whether peritoneal closure and retroperitoneal drainage can benefit clinical outcome of early gynecologic cancer patients who underwent retroperitoneal lymph node dissection.
Prospective feasibility study of perioperative nutrition in patients affected by primary retroperitoneal sarcoma
Idiopathic retroperitoneal fibrosis (IRF) is a rare disease characterised by the presence of a retroperitoneal periaortic fibro-inflammatory tissue which may entrap the ureters and cause r...
The goal of this study is to evaluate radiation treatment intended to increase the chance of curing your sarcoma and decrease the side effects of proton therapy. This study will also look...
A former branch of knowledge embracing the study, description, and classification of natural objects (as animals, plants, and minerals) and thus including the modern sciences of zoology, botany, and mineralogy insofar as they existed at that time. In the 17th, 18th, and 19th centuries it was much used for the generalized pursuit of certain areas of science. (Webster, 3d ed; from Dr. James H. Cassedy, NLM History of Medicine Division)
New abnormal growth of tissue in the RETROPERITONEAL SPACE.
A slowly progressive condition of unknown etiology, characterized by deposition of fibrous tissue in the retroperitoneal space compressing the ureters, great vessels, bile duct, and other structures. When associated with abdominal aortic aneurysm, it may be called chronic periaortitis or inflammatory perianeurysmal fibrosis.
The study of literature in its widest sense, including grammar, etymology, criticism, literary history, language history, linguistic history, systems of writing, and anything else that is relevant to literature or language viewed as literature. Philology as a discipline has both philosophical and scientific overtones.

Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
