This PA chest radiograph demonstrates an abnormal contour in the right hilar region, with visualization of the pulmonary vessels through the mass (the hilar overlay sign) indicating its posterior mediastinal location. On resection this was found to be a benign solitary fibrous tumor of the pleura.
Although they are often very large tumors (up to 40 cm. in diameter), over half are asymptomatic at diagnosis. [5] While some researchers have proposed that a SFT occupying at least 40% of the affected hemithorax be considered a "giant solitary fibrous tumor", [ 6 ] no such "giant" variant has yet been recognized within the most widely used ...
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Diagnosis usually by CT showing lobulated mass. Confirmation done by tissue biopsy of accompanying nodes if any, mediastinoscopy, mediastinotomy, or thoracotomy. FNA biopsy is usually not adequate. Treatment of mediastinal Hodgkin's involves chemotherapy and/or radiation. 5 year survival is now around 75%.
Lung cancer, most commonly squamous cell carcinoma, comprises 75–80% of these cases and non-Hodgkin lymphoma, most commonly diffuse large B-cell lymphoma, comprises 10–15%. Rare malignant causes include Hodgkin's lymphoma , metastatic cancers, leukemia , leiomyosarcoma of the mediastinal vessels, and plasmocytoma . [ 3 ]
A Klatskin tumor (or hilar cholangiocarcinoma) is a cholangiocarcinoma (cancer of the biliary tree) occurring at the confluence of the right and left hepatic bile ducts. The disease was named after Gerald Klatskin , who in 1965 described 15 cases and found some characteristics for this type of cholangiocarcinoma.
The ICD-10-CM and ICD-10-PCS were developed by the Centers for Medicare and Medicaid Services (CMS) and the National Center for Health Statistics (NCHS). [ 48 ] [ 49 ] There are over 70,000 ICD-10-PCS procedure codes and over 69,000 ICD-10-CM diagnosis codes, compared to about 3,800 procedure codes and roughly 14,000 diagnosis codes found in ...
Bilateral hilar lymphadenopathy is a bilateral enlargement of the lymph nodes of pulmonary hila. It is a radiographic term for the enlargement of mediastinal lymph nodes and is most commonly identified by a chest x-ray .
