Fine needle aspiration and small tissue biopsies have become a primary modality to achieve a definitive diagnosis of a mass-like lesion of the lung and mediastinum. This chapter delineated cytologic and histologic features of common and rare neoplastic and nonneoplastic mass-like lesions of the lung and mediastinum.Imaging modalities. Many mediastinal reflections can be appreciated at conventional radiography (CR), and their presence or distortion is the key to the interpretation of mediastinal abnormalities [].However, computed tomography (CT) is the most important tool in the evaluation of a mediastinal mass [].Characterisation on CT is based on specific attenuation of air, fat, water and calcium (Fig. 1).

Mediastinum Computed tomography (CT) is indispensable in imaging the mediastinum. Although conventional radiographs can show recognizable abnormalities in many patients with mediastinal pathology, radiographs are limited in their sensitivity and ability to delineate the extent of mediastinal abnormalities and the relationship of masses to specific mediastinal structures.

The heart is located in the middle mediastinum. Other visible structures of the mediastinum should also be checked when viewing a chest X-ray.
