Abstract

Pericardial effusion as an initial presentation of primary lung carcinoma is uncommon and poses diagnostic challenges due to its nonspecific clinical manifestation. Herein we report a case of a 51-year-old female with known diabetes mellitus, hypertension, and hypothyroidism who presented with generalized anasarca and dyspnea. Imaging revealed a right upper lobe mass with bilateral pulmonary metastases and moderate-to-severe pericardial effusion with early tamponade features. Cytological analysis of the pericardial fluid demonstrated malignant cells suggestive of adenocarcinoma, which was confirmed on histopathological examination of a lung biopsy. This case highlights the importance of considering malignancy, particularly adenocarcinoma of the lung, in patients presenting with pericardial effusion, even in the absence of prior cancer diagnosis.
