CTICasesVenous-Lymphatic Malformation with Hemangioma Features and Incidental Carcinoid Tumorlet

Imaging findings
An incidental finding on CT was a collection of tortuous, dysplastic vessels, some containing classic phlebolith-like calcifications, consistent with a venous-lymphatic malformation with hemangioma features. During resection, a separate pulmonary nodule was also found, which appeared distinct from the vascular malformation.
Key takeaways
Venous-lymphatic malformations can present as collections of abnormal vessels, often with phleboliths. An incidental carcinoid tumorlet was discovered in conjunction with the malformation. There is no established association in the literature between hemangiomas or venous-lymphatic malformations and carcinoid tumors, though pathologists frequently observe incidental carcinoid tumorlets.
