Intramuscular Venous Malformation: A Case Report
Le Thi Hong Vu
ABSTRACT
Intramuscular venous malformation (IVM) is a rare, benign vascular disorder characterized by dilated venous channels within muscle tissue, slow-flow hemodynamics, and a tendency to be overlooked because the lesions are not visible on physical inspection [1,2]. Accurate diagnosis relies on ultrasonography and magnetic resonance imaging (MRI), which allow precise lesion characterization and differentiation from soft-tissue tumors, thereby guiding appropriate treatment selection.
The International Society for the Study of Vascular Anomalies (ISSVA) has adopted the classification system first described by Mulliken and Glowacki in 1982, which has become the international standard for nomenclature. This system provides a unified framework for diagnosis, treatment, epidemiological research, prognosis, and evaluation of therapeutic outcomes. Within this classification, intramuscular venous malformations are categorized as slow-flow vascular anomalies [3].
