Neurilemmoma (NL), also termed schwannoma, presents as a well-circumscribed and encapsulated mass in the human body and is almost always solitary. CT scan of a patient with NL shows a round, ovoid, or lobulated well-demarcated solid mass of soft tissue density. Primary intrathoracic neurogenic tumors location varies. However, the development of such tumors is by far more common in the costovert...

Malignant peripheral nerve sheath tumor (MPNST) is a rare nerve sheath tumor derived from Schwann cells or pleuripotent cells of neural crest. Neurogenic tumors make about 10-20% of all mediastinal tumors. Incidence of MPNST is 0.001% in general population and 0.16% in patients with neurofibromatosis I (NF I). We report a case of 60 year female presenting with progressive cough and breathlessne...

and destruction of bone, usually the adjacent vertebrae and ribs posteriorly. There is a striking absence of intrathoracic metastasis, as shown by roentgenologic studies. No post-mortem studies were made in his series of seven cases. In two cases biopsy specimens showed carcinoma. One is recorded as carcinoma spinocellulare and in the other the type is not given. Pancoast calls these cancers “s...

Extensive intrathoracic tumors are rarely diagnosed radiologically without pre-existing symptoms. If located in the posterior mediastinum, it is most probably a neurogenic tumor. Schwannoma is the most frequent neurogenic neoplasia in this location, and most schwannomas are benign. To specify the diagnosis, a thoracic computed tomography must be done; if the growth is close to the medullary can...

Lung carcinoid tumors account for approximately 2% of lung cancers, with 10% of the tumors represented by the atypical type. While atypical carcinoids are metastatic to intrathoracic lymph nodes in approximately half of the cases on the initial presentation, distant metastases are seen in only 20% of the patients and are found most frequently in bones, liver, adrenal glands, and brain. We prese...

Dumbbell-shaped spinal extradural cavernous hemangioma is rare. The differential diagnosis of dumbbell-shaped spinal tumors based on magnetic resonance imaging includes schwannoma and lymphoma. Here, we report a dumbbell-shaped spinal extradural cavernous hemangioma with intrathoracic growth on T2-3 in a 64-year-old man complaining of right side infrascapular area back pain with no neurologic d...

An intrathoracic stomach is the end stage of a hiatal hernial diaphragm and has a very low incidence. Frequently the diagnosis is made incidentally by endoscopic or radiographic investigations. There could be no clinical symptoms, however an intrathoracic stomach could be life treating. In this case we report a 61-year-old woman with an atypical presentation of an intrathoracic stomach. The pat...

A total of 16 of 86 patients (19%) with non-Hodgkin's lymphoma were found to have intrathoracic disease in this retrospective study. Paratracheal, mediastinal, and hilar lymphadenopathy was the commonest manifestation followed by pulmonary lesions and pleural effusion. The lymphoma was at an advanced clinical stage in all the patients with intrathoracic disease. About one-third of the intrathor...

an intrathoracic goitre is a thyroid gland with more than 50% of its mass located below the thoracic inlet. This term can be further classified as an “incomplete” or a “complete” intrathoracic goitre. When the goitre is “incomplete,” a major portion of the goitre on the neck is visible, with its lower pole being substernal, subclavicular or intrathoracic. Conversely, a “complete” or “true” intr...
