Pulmonary Actinomycosis Imitating Lung Cancer on (18)F-FDG PET/CT: A Case Report and Literature Review.

Qiu L, Lan L, Feng Y, Huang Z, Chen Y - Korean J Radiol (2015)

Bottom Line: Here we report a case of 41-year-old man with a soft tissue density mass at right upper lung and palpable abscesses at right upper backside and right wrist. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography demonstrated a 7.8 × 5.0 cm mass with soft-tissue density in the upper lobe of the right lung with high metabolic activity.Final diagnosis of pulmonary actinomycosis with multiple abscesses was made.The patient responded well to antibiotics treatment.

ABSTRACT
Here we report a case of 41-year-old man with a soft tissue density mass at right upper lung and palpable abscesses at right upper backside and right wrist. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography demonstrated a 7.8 × 5.0 cm mass with soft-tissue density in the upper lobe of the right lung with high metabolic activity. The infiltrative mass extended to adjacent chest wall soft tissue. Final diagnosis of pulmonary actinomycosis with multiple abscesses was made. The patient responded well to antibiotics treatment.

41-year-old man with pulmonary actinomycosis imitating lung cancer with whole body 18F-FDG PET/CT scan.C. Maximum intensity projection showing mass at upper lobe of right lung and peripheral daughter lesions. D. 7.8 × 5.0 cm soft-tissue density mass is demonstrated. Mass has intense 18F-FDG accumulation (SUVmax = 13.3). E, F. Some opaque mottled shadows with 18F-FDG uptake are distributed in multiple lobes of right lung and inferior lobe of left lung. G-I. Infiltrative mass extended to adjacent chest wall, thoracodorsal muscle, and subcutaneous dermal tissues. SUVmax = maximal standardized uptake value, 18F-FDG PET/CT = 18F-fluorodeoxyglucose positron emission tomography/computed tomography

Maximum intensity projection showing mass at upper lobe of right lung and peripheral daughter lesions. D. 7.8 × 5.0 cm soft-tissue density mass is demonstrated.

Infiltrative mass extended to adjacent chest wall, thoracodorsal muscle, and subcutaneous dermal tissues. SUVmax = maximal standardized uptake value, 18F-FDG PET/CT = 18F-fluorodeoxyglucose positron emission tomography/computed tomography

Mentions: The patient underwent 18F-FDG PET/CT for further evaluation since this imaging method had improved sensitivity compared to 99mTc-MDP bone scintigraphy. 18F-FDG PET/CT (Fig. 1C, maximum intensity projection; Fig. 1D: D1, PET; D2, CT; D3, PET/CT fusion; Fig. 1G, axial; Fig. 1H, coronal; Fig. 1I, sagittal) demonstrated a 7.8 × 5.0 cm mass in the upper lobe of the right lung with soft-tissue density and spiculated margins similar to results of the previous CT scan. The density of the lesion was slightly asymmetrical with shaggy border. The mass had intense 18F-FDG accumulation with maximal standardized uptake value (SUVmax) of 13.3. The infiltrative mass extended to adjacent chest wall, thoracodorsal muscle, and subcutaneous dermal tissues. The soft tissues at the right upper backside was swelling with a high activity (SUVmax = 9.2). Additionally, some opaque mottled shadows were distributed in multiple lobes of the right lung and the inferior lobe of the left lung (Fig. 1E1, F1, PET; Fig. 1E2, F2, CT; Fig. 1E3, F3, PET/CT fusion). The sizes of these nodules ranged from 0.3 cm to 1.1 cm in diameter. The SUVmax of the highest activity nodule was 5.7.
