Computed tomography-guided core needle biopsy in tumor lesions of the thoracic cavity

Computed tomography-guided percutaneous transparietal biopsy in thoracic cavity lesions of tumor appearance with thick needle is a useful procedure for histological and immunohistochemical study. The aim was to describe our experience in the thoracic surgery unit of histological diagnostic accuracy and safety for the diagnosis of lesions in the peripheral pulmonary, mediastinal and subpleural thoracic cavities. A prospective, descriptive, cross-sectional analysis of tomography-guided transparietal biopsies of lung, mediastinal and subpleural lesions was performed. The age range: between 20 and 80 years, male predominance 90%, 75% corresponded to primary lung lesions in terms of histological and immunohistochemical diagnosis of biopsy material from primary lung lesions; Adenocarcinoma 58.8%; squamous or epidermoid carcinoma 23.5% Adenocarcinoma with lepidic component 5.8%. While in lesions of metastatic origin 11.7%. The reported pathology of malignant type was the most common, being primary bronchogenic tumors and metastatic lesions 95% the most frequent diagnoses. Sensitivity was 96.9%, while specificity was 100%. Likewise, the positive predictive value (PPV) was 100%, which indicates that the overall validity index (GVI) was 97.5%. In conclusion, image-guided BAG is a safe technique that allows obtaining a specific histological diagnosis.
