Isolated Spleen Metastasis from Lung Adenocarcinoma: A Case Report

Solitary splenic metastasis is extremely rare with few reported cases in literature. Current study reports the case of a 74-year-old, female patient who was diagnosed isolated spleen metastasis after lung adenocarcinoma, in the postoperative course. She presented with the incidental detection of nodular liver and central splenic lesions in a follow-up abdominal computed tomography (CT) scan after 5 years from the left lower lobectomy due to lung adenocarcinoma. By MRI examination, lesion in the liver was characterized as cystic and the central splenic lesion was found having a heterogeneous hypoechoic nodular character. Tru-cutbiopsy of spleen confirmed metastasis of lung adenocarcinoma. The patient underwent splenectomy. Although liver biopsy couldn’t detect any malignant tissue, lung cancer adenocarcinoma metastasis was diagnosed in splenectomy material. Herein, we report a case of incidentally found solitary splenic metastasis, 5 years after left lobectomy for lung adenocarcinoma.
