Metastatic breast cancer presenting with pleural effusion and pulmonary nodules: A multimodal diagnostic approach

ABSTRACT

We present the case of a 75-year-old female with a history of ductal carcinoma in situ (DCIS) of the right breast who later developed complications suggestive of metastatic disease. Through a coordinated multidisciplinary effort involving imaging, thoracentesis, pleuroscopy, and cryobiopsy, a diagnosis of metastatic adenocarcinoma was established. This case highlights the diagnostic importance of minimally invasive thoracic procedures in patients with suspected metastatic disease.
