Abstract

Paralabral cyst around hip is reported to be a cause of compression of the major neurovascular structures. Although, arthroscopic cyst and labral debridement is generally accepted as the effective treatment, there is limited literature available regarding treatment options for paralabral cysts in the hip. We present a case of paralabral cyst compressing left common femoral vein in the hip that was treated with sono-guided cyst aspiration followed by arthroscopic labral debridement.

  Fig. 1 (A) Preoperative anteroposterior radiograph of the left hip present no dysplasia or bony abnormalities. (B, C) Preoperative computed tomographic angiography and axial T2-weighted magnetic resonance image (MRI) show a large multi-lobulated cyst (arrows) compressing left common femoral vein. The common femoral vein (arrowheads) is flattened and displaced to anterior side. (D) Axial T2-weighted MRI shows increase of signal intensity suggesting labral tear (arrowhead) and connection between the cyst and the acetabulum (arrow).

  Fig. 2 Preoperative (A) coronal T1-weighted and (B) sagittal T2-weighted magnetic resonance image show a large multilobulated cyst (arrows) located medial and posterior to iliopsoas muscle.

• 

  Fig. 3 Arthroscopic view of the left hip joint from the anterolateral portal. (A) Arthroscopic examination shows anterosupeior labral tear with degeneration. (B) The torn labrum and degenerative tissues were debrided using a shaver.

  Fig. 4 Postoperative computed tomographic angiography at the 3-month follow up. The large cyst has disappeared and the displaced common femoral vein (arrow) has returned to its normal location.
