ABSTRACT

Objective To explore the CT characteristics of pneumonia-type mucinous adenocarcinoma (PTMA) to improve the diagnosis of the disease. Methods Thirty PTMA pathologically confirmed by surgery or lung puncture biopsy were retrospectively analyzed, and all patients underwent plain CT scan, including 16 enhanced scans. CT characteristics in lesion distribution, morphology, density, marginal border, air bronchial signs, vacuolus or cavity signs, enhancement patterns, angiography signs, and pulmonary metastasis were analyzed. Results 30 PTMA showed focal and diffuse mixed ground glass shadow and air cavity consolidation, Of these, 20 were multiple lung lobes involvement, Twenty cases of polished glass shadow with clear surrounding boundaries, Nineteen patients, associated with multiple nodules in both lungs, Dynamic observation of ground glass and nodule lesions fusion, increase, consolidation and dissemination to the two lungs; In 23 cases, smooth and straight edges with right Angle features; Interlobular fissure and swelling existed in 13 cases; "Dry branch-like" air bronchial signs were present in 17 lesions, There were multiple vacuoles or vacuoles in the 19 consolidation cases; Low flat sweep density (average 24.5 ± 8.4), After enhancement, mostly uneven mild enhancement (average 41.1 ± 16.6) with angiography; In two cases, the pleural fluid appeared, Pleural and mediastinal lymph node metastases were seen in two cases. Conclusion The characteristic CT manifestations of PTMA are branch-like bronchial, CT angiography, multiple vacuoles or vities, straight edges with right Angle, interlobular fissures swelling and lumen dissemination. Radiologists should be familiar with several characteristic imaging findings of the disease in order to make an early non-invasive diagnosis.
