We present a case of 52 year old male patient with tuberculous mediastinal lymphadenitis. During diagnostic process, CT scan was considered to be especially effective in the differentiation from other mediastinal tumors.
It was quite useful in diagnostic process to predict the internal structure of the lesion by the grade of CT density.
From this point of view, the accumulation of the basic data is mandatory in order to apply CT scan for diagnosing the character of lesions such as calcification and caseous necrosis.
