The present study reports the case of a 77-year-old female that was asymptomatic at presentation and was found to possess a lesion that was incidentally identified on a computed tomography (CT) scan. The CT scan revealed a non-homogeneous, hypodense, non-lobulated solid mass, ~1.2 cm in diameter, in the left upper lobe of the lung that demonstrated minimal contrast enhancement. The following CT scan was performed only two years later. This scan revealed that the non-homogeneous round mass had increased in size to ~1.7 cm in diameter, and possessed an irregular margin, in addition to being slightly lobulated with no calcification or fat. Combined positron emission tomography and CT revealed a lobulated mass that was ~1.9 cm in diameter, demonstrating an irregular margin with involvement of the mediastinal pleura. Slight uptake of 18 F-fluorodeoxyglucose was also detected. The final histological diagnosis was pulmonary hamartoma.
