Pulmonary benign metastasizing leiomyoma presenting as small, diffuse nodules

Pulmonary benign metastasizing leiomyoma with concurrent granulomatous inflammation: a diagnostic challenge

“…PBML on CT imaging can manifest in various patterns ( 3 ), including solitary or diffuse distribution, presenting as isolated small nodules or masses, and very rarely as diffuse miliary nodules ( 11 ). In this case, the nodules in both lungs exhibited a miliary-like random distribution, measuring approximately 2–4 mm in diameter.…”

Endobronchial Leiomyoma – When CT Demonstrates the Tumor: A Radio-Pathological Correlation

“…Within the lung, about half (51%) of cases affect the parenchyma, with 33 to 45% of cases being endobronchial tumors, the latter found in young or middle age patients with no gender predominance [1]. Leiomyoma metastases affecting the lung parenchyma are even more infrequent [3,[6][7][8]. The differential diagnosis for endobronchial lesions is commonly made with benign lesions such as papilloma, lipoma, and hamartoma, with the last two showing fat content [4].…”

Pulmonary benign metastasizing leiomyoma: a case description and analysis of the literature

“…They identified a mere 10 instances of BML in women without prior surgical intervention ( 2 ). Subsequently, our team conducted a study of the literature pertaining to BML from January 2017 to October 2023 in PubMed, retrieving only 9 cases in women devoid of a history of prior surgery ( 6 , 13 - 20 ). Among these cases, six exhibited metastases to the lung, one to the heart, and one to the lymph node.…”
