Case Presentation: A 72-year-old man underwent endoscopic resection of a 10-mm polypoid sessile lesion of the rectum. Histologic examination found a well-differentiated, low-grade (G1), neuroendocrine tumor. A thoracoabdominal CT scan was performed for staging purposes. The chest CT scan revealed a so-called cannonball-like distribution of multiple rounded nodules, with well-defined margins, ranging from 0.5 to 5 cm, scattered in both lungs (Figs 1A, 1B). The abdominal CT scan showed no abnormalities. A recent colonoscopy showed no evidence of malignancy. No prior chest imaging was available and the patient had never complained of respiratory symptoms. The patient was a former smoker, with a smoking history of 20 pack-years. He had a history of hypertension, mild stenosis of both carotid arteries, and benign prostatic hypertrophy. He reported the presence of long-standing multiple cutaneous hemangiomas on the trunk and face and a larger hemangiomatous lesion on his left lower limb, which was previously investigated by color Doppler ultrasound imaging. All these lesions were reported as unaltered and unchanged since early infancy.
