Imaging findings of a case report of intravenous lipoleiomyomatosis

Background: Intravenous leiomyomatosis (IVL) is a special type of uterine leiomyoma and is rare. Intravenous lipoleiomyomatosis (LPL) is a rare subtype of IVL, distinguished by the presence of adipose tissue. Although histologically benign, this disease exhibits aggressive biological behavior such as local invasion and high recurrence rate. The disease initially presents with no obvious clinical features, and cardiac symptoms may only appear in the later stages. Diagnosis primarily relies on imaging studies, and due to its rarity and atypical clinical presentation, imaging diagnosis can be challenging, leading to misdiagnosis and missed diagnosis. Previously, there was no report on the imaging findings of this disease.
