ABSTRACT

Diagnosis: Hill-Sach’s lesion with underlying subcortical bone contusion and subchondral cyst formation consistent with chronicity.

History: 42 yo man presents with onset of right shoulder pain for two years, combined with right upper extremity numbness and tingling.

Findings: A-P radiograph of the right shoulder in internal rotation shows a grooved defect in the posterolateral humeral head. Axial proton-density with fat saturation MR image shows an area of high signal intensity of the posterolateral humeral head and overlying cartilage consistent with a Hill-Sachs lesion. Proton-density and the T2-weighted with fat sat coronal oblique MR images show the Hill-Sach’s lesion of the humeral head with fractured cortex. T2-weighted with fat sat sagittal oblique MR image shows the high signal intensity edema and subchondral cyst formation in humeral head beneath the Hill-Sach’s fracture. There is no evidence of bony Bankart lesion on the plain radiographs or bony or cartilaginous Bankart lesion on the MR images.

Ddx: The findings are typical for Hill-Sach’s lesion.

Exam: On physical exam there is no obvious deformity of right upper extremity and the shoulder girdles are symmetrical with normal contours. Pain in right upper extremity, with palpation internal and external rotation, and with passive and active range of motion. Special tests: Negative sulcus sign, positive apprehension test. No neurological deficits noted.

No MeSH data available.
