It is uncertain whether DWI is more useful than positron emission tomography-computed tomography (PET-CT) for distinguishing benign from malignant mediastinal tumors and mass lesions. MATERIALS AND METHODS Sixteen malignant mediastinal tumors (...
Mediastinal immature teratoma in autopsy of fetus is a very rare phenomena which has been reported so far just in two cases. The case of the present study was a 24-week dead female fetus delivered by C/S for intrauterine death.

Mediastinal hematomas not associated with aortic disruption are thought to be common entities, and it is generally believed that most will spontaneously resolve. However, large mediastinal hematomas can cause fluctuations in cardiorespiratory physiology and can even cause death. Three cases of mediastinal hematomas are presented, as well as their surgical approach. Mediastinal hematomas should ...
ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. true malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. there are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only...
right atrial dilation due to left heart disease is a common complication among adults. the present review aimed to describe a case of massively dilated right atrium in a female patient presenting with valvular heart disease and no atrial fibrillation. the results of chest x-ray revealed a large opacity filling the lower right hemithorax, falsely interpreted as a mediastinal mass. during the tra...

Background: It is well known that, at the time of the initial presentation of patients with non-small cell lung cancer, N-status is very important in accurate staging and avoiding inappropriate surgical procedures. Also, if mediastinal lymph node metastasis (N2) of non-small cell lung cancer (stage IIIA) is present, neoadjuvant (preoperative) chemora-diotherapy is indicated therefore a quick an...
