RESUMEN
This work aimed to evaluate diagnostic accuracy of percutaneous CT guided biopsy versus thoracoscopic lung biopsy in realizing the etiology of peripheral lung lesions. The study included 40 patients with peripheral lung lesions. The patients subjected to the clinical history and examination, plain X-ray chest, routine laboratory investigations, CT guided biopsy and thoracoscopic lung biopsy. The final diagnosis in both groups were 32 malignant lesions and 8 benign lesions with a sensitivity of CT guided biopsy 75% and specificity 100%, while the sensitivity and specificity of thoracoscopic biopsy was 100%. Thoracoscopic biopsy is an important tool in diagnosing peripheral lung lesions whether small or large. Thoracoscopy provides higher degree of sensitivity in diagnosis of peripheral pulmonary lesion versus CT guided biopsy
