Primary pulmonary choriocarcinoma (PPC) is frequently fatal due to difficulties in diagnosis. Few cases of PPC are bilateral and involve exceptionally large nodules. Here, we report an unusual case of PPC involving disseminated bilateral nodules, which was misdiagnosed as tuberculosis, but successfully treated using chemotherapy. A review of 65 cases revealed six cases of bilateral disease, including the present one. Patients treated with surgery, chemotherapy, or a combination of both showed similar treatment outcomes; however, chemotherapy may be the preferred option. Despite its rarity, PPC should be included in the differential diagnosis for all lung nodules to enable early detection.
