case_images: MRI of the pelvis showed an irritation of the sciatic nerve by a vascular malformation in proximity to the lesser trochanter [Figures 2-4].
case_images: 3D- reconstruction illustrating compression of the sciatic nerve (orange) by a vascular malformation (red) located between the nerve and the lesser trochanter (trochanter in yellow). The reconstruction was created with the Brainlab iPlan Cranial software (Brainlab, Munich, Germany).
