## Abstract

Venous malformations (VMs) are vascular malformations affecting a small portion of the population. A 53-year-old woman presented with a congenital VM on the left gluteal region confirmed through clinical imaging and histopathology. Treatment with sclerotherapy led to significant improvement. VMs often cause pain, swelling, or mobility limitations. Diagnosis relies on Doppler ultrasound and MRI, while sclerotherapy is the preferred treatment due to its safety and efficacy. This case highlights sclerotherapy as a key treatment in a multidisciplinary management approach.
