Paraganglioma is a rare tumor that should be included in the differential diagnosis of retroperitoneal tumors. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has emerged as an effective tool in the diagnosis of these lesions. A 37-year-old female patient with a history of microcytic anemia underwent EUS-FNA and was diagnosed with a neuroendocrine tumor by histopathological and immunohistochemical analysis. The tumor was surgically removed, and the final diagnosis was paraganglioma. This case report emphasizes the importance of EUS in the evaluation of this type of lesion.
