Transient synovitis of the hip

Case contributed by Maulik S Patel
Diagnosis probable


Non-traumatic onset of right hip pain, limping - 3 - 4 days. No fever. Normal lab reports.

Patient Data

Age: 5 years
Gender: Male

There is mild anechoic effusion in anterior recess of affected right hip joint. There is no erosion of cortex. Femoral vessels were patent. Anterior thigh muscles showed normal echopattern.

Asymptomatic left hip joint does not show effusion.

Case Discussion

In the absence of destructive features or heterogeneous effusion to suggest septic arthritis, imaging findings are suggestive of transient synovitis of the hip joint. These differentials could be distinguished on a joint aspirate.
