Incidental Multiple Pulmonary Nodules in a Middle-Aged Woman.

Answer: D A 54-year-old lady underwent a screening cardiac computed tomography (CT) scan for coronary calcium which found incidental multiple sub-centimetre pulmonary nodules of varying sizes present in both lungs. This finding was confirmed on a CT of the chest (Fig. 1). Plain chest radiography was not done before surgery. She was a lifelong non-smoker with a history of total hysterectomy 15 years ago for menorrhagia secondary to fibroids. Her father had colon and lung cancer. Her mother had pulmonary tuberculosis, colon, lung and breast cancer. The patient had no cough, dyspnoea or constitutional symptoms including fever, night sweats, loss of weight and appetite. Physical examination was unremarkable. She had a recent mammography which was normal. Positron emission tomography-computed tomography (PET-CT) scan was performed to evaluate for the presence of malignancy elsewhere with lung metastases, but no hypermetabolic primary malignancy was detected. Autoimmune workup was negative.
