Chest CT of multiple PSP. This is a rare case of multiple PSP. The patient’s physical examination revealed the presence of multiple nodules in both lungs. A chest CT scan confirmed the existence of a total of 4 circular pulmonary nodules, distributed as follows: 1 in the upper lobe of the right lung, 1 in the lower lobe of the right lung, 1 in the upper lobe of the left lung, and 1 in the lower lobe of the left lung. The largest nodule, measuring 26 mm in diameter, was surgically excised from the left upper lobe and subjected to pathological analysis, which confirmed the diagnosis of PSP. Consequently, the final diagnosis was determined to be multiple PSP, and the patient is currently undergoing follow-up care.
