56 year-old male. Left hip pain. Assess for abnormality. Please see hip xray (4/2015) density noted on femoral neck. There is a irregular focus of low signal intensity within the the femoral neck along the posterior cortex associated with a tiny central focus of relatively high signal intensity. The etiology of this finding is uncertain but it is not associated with any significant edema and does not have a typical appearance of a metastatic focus. We suspect it is benign in etiology, perhaps a focus of corticotrabecular thickening. This likely corresponds to the focus of sclerosis seen on recent radiographs. Degenerative disk disease affects the lower lumbar spine, most severely at L5-S1. Mild osteoarthritis affects both hips. There is increased signal intensity within the anterosuperior acetabular labrum on the left suggesting degeneration or degenerative tearing. There is slight prominence of the anterior aspect of the left femoral head/neck junction with an alpha angle of 55 degrees suggesting a borderline CAM deformity. Mild heterogeneity of the bone marrow on T1-weighted images likely represents residual red marrow. The musculature is unremarkable. On the large field of view T2 weighted images, there are small elongated foci of high signal intensity within the left sciatic nerve, which may represent prominent fascicles or perhaps tiny benign nerve sheath tumors, but these not necessarily of any clinical significance.
1. Cortically based focus of low signal intensity within the posterior aspect of the left femoral neck likely corresponds to the sclerosis seen on the recent radiographs. While its etiology is uncertain, we suspect that it is benign and of doubtful clinical significance.2. Degenerative arthritic changes and other findings as described above.
