Abstract

The presence of calcification in a pulmonary nodule is usually a sing of benignity. However, infrequentlycalcification can occur in a malignant lesion. Adenoid cystic carcinoma of the lung is a type of bronchialadenoma, and a rare disease. We recently experienced a case of adenoid cystic carcinoma with diffuse andhomogenous calcification involving the right middle lobe associated with regional lymph node metastasis. CT examination revealed the mass to have high Hounsfied unit of 193, which is unusual for a malignant tumor whichusually has a Hounsfield unit lower than 165. From this case, it is learned that adenoid cystic carcinoma has highHounsfield unit when it is calcified.
