From: MR imaging of venous malformations: sciatic nerve infiltration patterns and involved muscle groups
Widespread venous malformation of the right thigh infiltrating into gluteal and hamstring muscles and the sciatic nerve. (Patient 20). The sciatic nerve is marked with an arrow on the affected and healthy side. Outlined areas signify infiltrated muscles. (A) All gluteal muscles infiltrated by the VM. (B) Distal portion of gluteus maximus and proximal hamstrings infiltrated by the VM. (C) Hamstring muscles (semimembranosus, semitendinosus, biceps femoris) infiltrated by the VM.
