Summary
Introduction: Renal cell carcinoma (RCC) metastases occur in the lungs in 50-60%. The most common manifestations are solitary or multiple nodules.
Case report: There was a possibility of novum, solitary lung metastasis during imaging examinations of our patient who underwent radical nephrectomy due to kidney cancer. Based on the CT scan, the patient has already been scheduled for oncology treatment; however, due to the good general condition of the patient, the possibility of a single metastasis, the focal considered to be operable based on the location of the lungs. Surgery was performed at the National Institute of Oncology (OOI). The histological examination was an unexpected finding: a pulmonary infarction caused by a Dirofilaria-parasite, which is still rare in Hungary, without any signs of malignancy.
Conclusion: Based on the experience of recent years, it is worth thinking about this zoonosis in the background of a solitary laesion described in the lungs, which is still considered sporadic, but is increasing due to the growing number of human nematode infections. The options for oncological treatment of advanced metastatic kidney cancer have been expanded in recent years with a number of new options that are cause for optimism. In addition to presenting the rare case, we also aim to review the treatment options for metastatic kidney tumors.
