Reason: met renal cell ca History: c/o right hip pain Mild osteoarthritis affects the right hip. Note is made of a focus of enhancing increased signal abnormality on fluid sensitive sequences within the medial aspect of the inferior acetabulum which likely represents an enhancing subchondral cyst. A small chronic erosion is considered a less likely differential consideration. There is thin synovial enhancement on postcontrast sequences which is likely within normal limits and of no current clinical significance. Otherwise no bone marrow signal abnormality is identified. Additionally, note is made of a 1.4 cm focus of fluid signal intensity along the posterior superior aspect of the acetabulum which may reflect paralabral cyst formation indicating degeneration and probable degenerative tearing of the acetabular labrum at the 11:00 position, within the limitations of this non arthrogram study. The imaged musculature of the right hip is unremarkable.
Osteoarthritis of the right hip. No evidence of osseous metastatic disease. Findings indicating degeneration and degenerative tearing of the acetabular labrum with probable small paralabral cyst formation.
