Pleural plaques are patches of thickened, scarred tissue that form on the pleura, the thin lining surrounding the lungs and the inside of the chest wall. Unlike asbestosis, which scars the lung tissue itself, pleural plaques stay confined to that outer lining and are generally considered less severe. Asbestos Ships works with veterans whose imaging turned up plaques years after their time aboard ship, helping them understand what that finding could mean for a VA claim.
Inhaled asbestos fibers travel through the respiratory tract and can reach the pleural space surrounding the lungs. Once there, the fibers trigger inflammation, and over time that response produces localized patches of dense, collagen-rich tissue. These patches often calcify, which is part of why they tend to show up clearly on chest imaging.
Plaques most commonly develop along the lower chest wall and diaphragm. Many people never notice symptoms at all, and plaques are frequently discovered by accident during an X-ray or CT scan done for an unrelated reason.
What the research shows about shipyard exposure
Research from a shipyard region in northeastern Italy found pleural plaques in 86.7% of shipyard workers studied, a rate notably higher than in the general population examined alongside them. That kind of concentrated finding among shipyard workers specifically strengthens the case for Navy veterans who performed similar construction, repair, or maintenance work.
Separate large-scale studies using high-resolution CT scans have consistently found that the odds of developing plaques rise alongside both how much asbestos someone was exposed to and how long ago that exposure happened. This dose and time relationship has held up across multiple research populations, not just one isolated study.
Why plaques often surface decades later
Pleural plaques rarely appear right away. Research following formerly exposed workers found that plaques showed up an average of more than four decades after the first asbestos exposure, closely matching the VA's general estimate that asbestos-related disease symptoms can take 20 to 50 years to appear.
That timeline lines up with how many Navy veterans experience this diagnosis, often discovering plaques on an unrelated scan long after their service ended. It's also why connecting a current finding back to decades-old duty stations depends so heavily on having the right records.
Where Navy veterans encountered asbestos
Asbestos was built into older Navy ships throughout engine rooms, boiler rooms, and other below-deck spaces, mainly for fire protection and insulation. The materials below were among the most common sources aboard ship.
- Pipe coverings, known as lagging
- Gaskets, valves, and cement products
- Adhesives and other heat-resistant materials
Veterans who served aboard ships with keels laid before 1983, worked below deck before the early 1990s, or handled damaged asbestos materials during repairs fall into the groups most likely to have faced this kind of exposure.
Building an asbestos-related claim
Pleural plaques are recognized as an asbestos-related condition, so a veteran can potentially qualify for compensation the same way as with other asbestos diseases. A claim generally needs to show a few specific things.
- Evidence that asbestos exposure took place during military service
- A diagnosed condition connected to that exposure
- A medical opinion linking the diagnosis to the in-service exposure
The VA may request its own medical exam to weigh in on that connection before deciding a claim.
How the VA rates pleural plaques
Pleural plaques don't have a diagnostic code of their own in the VA's rating schedule. Instead, the VA rates them by analogy to asbestosis, using the same lung-function-based formula under Diagnostic Code 6833.
That means a pleural plaques diagnosis alone doesn't set the rating. The percentage depends on measured breathing function, from a 10 percent rating tied to mild reductions up to 100 percent for severe impairment or the need for supplemental oxygen.
Talk to Asbestos Ships about your pleural plaques diagnosis
An incidental finding on a scan doesn't come with instructions for what to do next, especially when the exposure happened decades earlier aboard ship. Asbestos Ships helps veterans figure out the right path forward.
- Referrals to VA-accredited representatives who handle these claims without upfront fees
- Plain-language information on the type of service and medical records that support a claim
- Help locating your nearest VA regional office or medical center
- Connections to legal resources for compensation options outside the VA system
A pleural plaques finding might seem minor compared to other asbestos-related diseases, but it still points to real exposure that could support a claim. Our team can help you sort out whether that exposure ties back to your service. Get in touch to see what your next step could look like.
