|Patient: 50 year old male|
| History: |
11/2/2003 - Right hip radiographs: 50 year old male with right hip pain, no history of trauma.
7/3/2006 - MRI bilateral hips: Chronic bilateral hip pain
| Findings: |
11/2/2003 - Frog leg lateral projection of the right hip shows a cyst with well defined corticated margins less than 1 cm in diameter in the superolateral portion of the femoral head/neck.
|Diagnosis: Synovial herniation pit.|
| Discussion: |
Round, well-circumscribed lucent areas located at the anterolateral cortex of the femoral neck are a normal variant termed synovial herniation pits (Pitt's pit). These pseudolesions are thought to represent sites of ingrowth of fibrous and cartilaginous elements. The only confusing feature is that they may be seen to enlarge over time, possibly related to changing mechanisms such as pressure and the abrasive effect of the overlying hip capsule and anterior muscles.
