A fifty-eight-year-old female patient was referred to our clinic with left-sided arm and shoulder pain. Upon radiological investigation, a mass in the apical segment of the left upper lobe causing vertebra destruction was detected. The patient was operated on with a working diagnosis of a Pancoast tumor. However, during the operation the lesion was identified as a hydatid cyst. This case report aims to emphasize that, despite its rarity, hydatidosis should be included among the differential diagnosis of Pancoast tumors in endemic regions.
