Abstract:
Introduction:
Pulmonary enteric adenocarcinoma (PEAC) is an extremely rare variant of lung adenocarcinoma characterized by pathological features similar to
those of colorectal adenocarcinoma. It is mostly observed on computed tomography (CT) and positron emission tomography (PET)/CT as solitary
or multiple nodules/masses in the lung. It tends to grow rapidly and is difficult to distinguish from lung metastatic colorectal cancer. Herein, we
have presented a case of PEAC with special imaging findings.
Case Presentation:
A chest CT scan of a 72-year-old man with suspected chronic pneumonia revealed a well-defined consolidation in the upper lobe of the left lung.
The lesion was slightly enlarged at the 9-month follow-up, and low FDG accumulation was subsequently observed using 18F-fluorodeoxyglucose
(18F-FDG) PET/CT scans. The patient was later diagnosed with PEAC through percutaneous lung biopsy.
Conclusion:
Our case has demonstrated specific imaging findings of PEAC.
