A 54-year-old woman was referred to our hospital because computed tomography (CT) revealed multiple lung nodules during a health checkup. The nodules were up to 5 mm in diameter and randomly distributed in both lungs, appearing ring-shaped. No clinical symptoms were present. However, the nodes proliferated, and multiple lung metastases could not be ruled out, so a biopsy was performed to establish a diagnosis. She was diagnosed with minute pulmonary meningothelial-like nodules (MPMNs), and her condition had not deteriorated at the latest follow-up. Although rare, MPMNs can proliferate for a short time, but a biopsy to exclude malignant causes is essential.
一位 54 岁女性因体检时计算机断层扫描（CT）发现多个肺结节而被转至我院。这些结节最大直径达 5 毫米，随机分布于双肺，呈环形。患者无临床症状。然而，结节在增殖，不能排除多发肺转移，故行活检以明确诊断。患者被诊断为微小肺脑膜瘤样结节（MPMNs），在最近的随访中病情未恶化。虽然罕见，MPMNs 可在短时间内增殖，但为排除恶性病因进行活检至关重要。
