Pancreatic cancer presenting with pulmonary cannonball lesions

Abstract

Cannonball lesions are numerous, well-circumscribed, round pulmonary lesions and may be identified on plain radiograph or advanced imaging. This morphology can be associated with infectious causes, rheumatologic disease and metastatic disease. Classically, when cannonball lesions are associated with metastatic disease, they are seen in renal cell carcinoma and choriocarcinoma. We report a case of a 62-year-old Middle Eastern male who presented with shortness of breath, chest pain and fatigue and was found to have bilateral multiple pulmonary cannonball lesions and mass in the pancreas. Biopsy of one the lung lesions was consistent with pancreatic cancer. Our case adds to the limited literature available regarding cannonball lung lesions in the setting of pancreatic cancer. Health care providers should be aware of the various etiologies of cannonball lesions.

Atypical Radiology Imaging of Squamous Cell Lung Carcinoma: A Case Report and Narrative Review

“…Immunotherapeutic targets like Ipilimumab and nivolumab will conduct the program cell death of the ligand-1 (PD-L1), program Although X-ray findings mimicking "Cannonball" lung lesions typically denote malignancy metastases [1], this does not necessarily mean that way. Table 2 denotes various diagnoses and each lung imaging characteristic [1,17]. A study reported a "Cannonball" appearance after spontaneous rib fracture [18], while pulmonary cavernous hemangiomas and benign satellite tumors also manifested in lung lesions mimicking Cannonball [5,19].…”
