Enhanced CT reveals a subpleural nodular pattern in the lower lobe of the right lung, indicating that the patient may have pulmonary nodules. Enhanced CT reveals subpleural nodular shadow in the lower lobe of the right lung, indicating that the patient may have pulmonary nodules, which are focal, rounded, and hyperdense solid or sub-solid lung shadows ≤3cm in diameter, and belong to one of the common diseases of the lung. If the size of the nodule is within 0.8cm, and the patient does not have obvious symptoms such as dry cough, low-grade fever, night sweats, etc., there is no need for special treatment, and the patient should go to the hospital for regular checkups. If the size of the lung nodule exceeds 0.8cm, further pathological screening is needed to exclude the possibility of malignant tumors in the lung. It is recommended that patients who find subpleural nodular shadows in the lower lobe of the right lung when doing enhanced CT should promptly clarify the cause in the hospital and be treated under the guidance of the doctor.
