Summary: | To evaluate the diagnostic accuracy of percutaneous image-guided cutting-needle biopsy of pleural thickening in the presence of a suspected malignant pleural effusion.
Thirty-three adult patients with diffuse or focal pleural thickening (median, 1.0 cm; range, 0.2-6.0 cm), pleural effusion, and suspected pleural malignancy underwent percutaneous image-guided cutting-needle biopsy. Biopsy guidance was performed with computed tomography in 24 patients and ultrasonography in nine patients. A final diagnosis of benign or malignant disease was established with radiologic and clinical follow-up findings and with other histologic or cytologic findings, when available.
A correct histologic diagnosis of malignant disease was made in 21 of 24 patients (sensitivity, 88%; specificity, 100%), including 13 of 14 patients with mesothelioma (sensitivity, 93%). A correct histologic diagnosis of benign pleural disease was made in nine patients. Positive and negative predictive values for malignant disease were 100% and 75%, respectively. The overall accuracy was 91%. Complications comprised a chest wall hematoma in one patient.
Image-guided percutaneous cutting-needle biopsy of pleural thickening in the presence of a pleural effusion is a safe procedure, with an overall accuracy of 91% in the diagnosis of malignancy. |
