  • Labral tear: MR-Arthrography

      • 26-year-old man with painful snapping hip.

      Arthro-MRI with T1-weighted sequences in coronal and sagittal planes show:

      - superior linear tear (white arrow) with loss of the triangular shape at the free edge (blue arrow).

      - anterior tear: the labrum is displaced caudally and secondary to a proximal lesion (yellow arrows).

       

  • Labral tear: CT-Arthrography

      • Hip pain, specially in flexion-abduction-lateral rotation.

       

      Anterior labral split () with communication to articular surface (). Normal acetabular and femoral head cartilage. ().

      Large heterogeneous mucoid cyst () located deep to the psoas muscle (), superficial to a antero superior labral tear (), associated with a subchondral acetabular bone cyst () and a narrowing antero superior joint space.

      • Chronic hip pain in 65-year-old woman.

      T2-weighted sequences in oblique coronal and axial planes show paralabral cyst with extension in the acetabulum. Article T. Magee
