Presentation
Cough, weight loss.
Patient Data
Large lobulated soft tissue mass in the left lower lobe of the lung, with invasion of the left main bronchus and obstruction of the lower segmental bronchi. Left lower lobe partial atelectasis due to obstruction and fluid-filled lower segmental bronchi. Right low cervical /1R and right upper paratracheal /2R lymphadenopathy. Post-obstructive hepatisation of the left lower lobe.
The [18F]-FDG PET/CT was done after 3 months. The tumor of the left lower lobe with high FDG uptake. Multiple high metabolic lesions of the left lower lobe which are hyperdense compared to the background: carcinomatosis of the left lower lobe. Metastatic lymphadenopathy of the right low cervical and upper paratracheal groups with high FDG uptake.
Case Discussion
Lung hepatisation is an imaging term that describes airless consolidated lung that resembles the liver. In this case, the lung consolidation and partial atelectasis is caused by obstruction of the left lower lobar bronchus due to the soft tissue mass.
