65-year-old female with pain in the pelvic region and thigh. Concern for malignancy. Evaluate for mass. LEFT HIP:ACETABULAR LABRUM: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: Heterogeneous bone marrow signal abnormality may represent residual islands of red marrow. Mild degenerative changes affect the left hip including joint space narrowing and osteophyte formation.SOFT TISSUES: No significant abnormality noted. RIGHT HIP:ACETABULAR LABRUM: Although this examination was not protocoled for evaluation of the acetabular labrum, there is increased linear signal abnormality traversing the anterior acetabular labrum consistent with a labral tear.ARTICULAR CARTILAGE AND BONE: Heterogeneous bone marrow signal abnormality may represent residual islands of red marrow. Mild degenerative changes affect the right hip including joint space narrowing and osteophyte formation. There is a subcentimeter focus of increased signal abnormality right posterior ilium with associated enhancement on postcontrast sequences (series 5; image 3). SOFT TISSUES: No significant abnormality noted. ADDITIONAL
1. Degenerative tearing of the anterior right acetabular labrum. No evidence of acute fracture or malalignment. 2. Nonspecific subcentimeter enhancing focus within the right posterior ilium is better characterized on the patient's recent lumbar spine MRI examination and may represent a hemangioma. Otherwise no evidence of metastatic disease or focal mass lesions.
