Abstract
Tuberculosis can mimic all pathological considerations of the lung and can present in many various forms and appearances. Most common radiographic appearances are cavitary, fibroproductive, exudative, acinary, micro and macronodular and miliary types. Six patients (5 men; ages ranging from 38 to 74 years) who presented at our clinic during previous years were evaluated. In this case series report we discussed the consideration that, very rarely, post- primary lung tuberculosis presenting with large nodular and mass-like forms in a chest X-ray or tomography scan, can be considered as having a neoplastic pattern.
