Enhanced axial CT (A) shows diffuse pleural thickening (arrow) with a maximum thickness of 3.17 mm. US image for the corresponding lesion on CT (B) shows diffuse pleural thickening (arrowheads) with a maximum thickness of 3.25 mm. The needle pathway length, measured as the needle length through the pleural lesion, was 6.54 mm (asterisk). Pleural puncture angle (exact value not indicated) is depicted as the angle between the outer line of the pleura and the biopsy needle (thin arrow).

November 9, 2020 — According to an open-access article in ARRS’ American Journal of Roentgenology (AJR), ultrasound (US)-guided percutaneous pleural needle biopsy (PCPNB) has excellent diagnostic accuracy for small pleural lesions.

“US-guided PCPNB is highly likely to be diagnostic for small pleural lesions with nodular morphology on CT or US, or with pleural thickness ≥ 4.5 mm,” explained Jongmin Park and colleagues from South Korea’s Kyungpook National University.

To determine the diagnostic yield of US-guided PCPNB for small (≤ 2 cm) pleural lesions and the impact of computed tomography (CT) and US morphologic and technical factors, Park’s team retrospectively studied 103 patients (73 men, 30 women; mean age, 60.8) who underwent US-guided PCPNB of a small pleural lesion by a single experienced operator from July 2013 to December 2019. Histopathological results established final diagnosis, including from repeat US-guided and CT-guided biopsies, as well as imaging and clinical follow-up. CT and US assessed pleural morphology and thickness, while US measured needle pathway length throughout the pleura.

Summarizing their results, Park et al. noted: “[US-guided PCPNB] of small pleural lesions had a diagnostic accuracy of 85.4%. The yield was 96.4% for nodular CT lesions, 95.0% for diffuse CT lesions with thickness ≥4.5 mm, 55.6% for diffuse CT lesions with thickness.”

Repeating their assessments on both CT and US 2 weeks later yielded the representative measurements as shown in the images.

“In multivariable analysis,” the authors of this AJR article concluded, “pleural morphology on US and needle pathway length through the pleura independently predicted diagnostic yield,” adding that if the pleura is nodular or thicker than 4.5 mm on CT, US-guided PCPNB is justifiable as an initial or repeat diagnostic test.
