Signs and Findings in Lung Masses

Benign Hamartoma

79 year old male with a 5.5cms mass in the left upper lobe shown on frontal views of the chest taken 4 years apart and showing no growth. The mass is characterized by heterogeneous calcifications Findings are consistent with a hamartoma

Cancer

Halo Sign Around a Malignant Mass
CT in the axial plane demonstrates a large, spiculated mass in the right upper lobe with surrounding halo likely reflecting hemorrhage or lymphatic edema around the mass. In addition, there is evidence of irregular interlobular septal thickening likely reflecting lymphatic invasion and indicating lymphangitis carcinomatosa. There is irregular thickening of the major fissure suggesting involvement.

Calcification in Malignancy

BREAST CA BILATERAL PRIMARY LUNG CANCER AND IPF (UIP)
73 year old female with left mastectomy and IPF with new onset bilateral upper lobe masses. The LUL mass has scattered calcifications, and the right shows early cavitation.
Both lesions are PET positive
The LUL lesion was biopsied revealing squamous cell carcinoma with calcifications showing progressive growth and enlarging ipsilateral lymphadenopathy.
