Small subpleural nodular shadow in the left upper lung is usually benign, and if it is less than five millimeters, it is more likely to be benign. You can review the chest CT in 3 to 6 months if the size of the nodule fluctuates in the range of 1 to 2 millimeters.
There are many diseases that cause small nodular shadows in the lung, the most worrisome being lung cancer, but also various sarcoidosis of the lung, pneumonia, tuberculosis, pulmonary fungal disease, benign tumors such as misshapen tumors, inflammatory pseudotumors, adenomas, and some anatomic bronchial and vascular variants or malformations of the lung, which are generally rare in patients with cancer and progress slowly and are generally not a cause for concern.
