Hello and welcome to the forum. I greatly apologize for the delay in answering your question! Are there any updates as I suspect there are. This article is a little technical but it discusses perifissural nodules of the lung. https://radiopaedia.org/articles/perifissural-lung-nodules This is a comprehensive article on lung nodules in general. https://my.clevelandclinic.org/health/diseases/14799-pulmonary-nodules Of note, 95% of nodules are benign. You have quite a few suspicious findings though and am hoping that you get clarity from your doctor. Please let us know.
