CTICasesDiffuse pulmonary meningotheliomatosis
Imaging findings
CT demonstrates multiple tiny, bilateral, basal-predominant lung nodules containing small, regular central lucencies ('micro-Cheerios' or cheerio sign), in a patient with chronic aspiration.
Key takeaways
Diffuse pulmonary meningotheliomatosis is a rare, benign condition characterized by multiple tiny meningothelial-like nodules. They are typically asymptomatic, can show a central lucency ('cheerio sign'), and are often associated with chronic lung injury or aspiration.
