Question

multiple choice question
a \popcorn\ calcification pattern within a lung mass is most characteristic of:
please select your answer...
a tuberculosis
b metastatic osteosarcoma
c hamartoma
d bronchogenic carcinoma

Explanation:

Hamartomas are benign tumors. On imaging, a "popcorn" - like calcification pattern is a classic radiological feature of pulmonary hamartomas. Tuberculosis typically shows different types of calcifications (e.g., dense, nodular in a more fibrotic - granulomatous pattern). Metastatic osteosarcoma would have osseous - like calcifications related to bone - forming tumor cells. Bronchogenic carcinoma may have calcifications, but they are usually not in the "popcorn" pattern.

Answer:

C. Hamartoma
