case_images: (a) Preoperative SPECT-CT after removing of metal artefacts. There is no visible tracer uptake in hip region. (b) Soft tissue reconstruction showing visible bursa with a comparable size to acetabular cup.
  SPECT-CT: Single-photon emission computed tomography-computed tomography.

case_images: On the images of the SPECT-CT, no accumulation of the isotopes was found and the bone cement mantle was intact (Figure 1).
case_images: (a) Preoperative ultrasound test, longitudinal view. Occluded vein is marked above the cyst. (b) Preoperative ultrasound test, the cross-section of the inguinal area showing a visible contact between structures.

case_images: Tochigi, Japan) targeting the cystic mass. The imaging examinations confirmed our diagnosis, showing a direct contact of the iliopectineal bursa and femoral vein (Figure 2). 
case_images: Anterior approach of the hip. The cystic mass starts between ventral pseudo-capsule and iliopsoas muscle.

case_images: Two incisions were made with special care to the width of the skin bridge between them; the medial end of the bursa was managed through a classical incision for reaching the neurovascular bundle; for the lateral end and to reach the joint, we used the anterior approach of the hip (Figure 3 and 4).
case_images: Approach for the neurovascular bundle. Forceps, being upper on the picture (closer to the midline in reality), holds vessels, lower forceps grasp wall of the bursa.
