Diagnosis: Reactive arthritis

  
 

Equipment: AU4-Idea, Esaote Biomedica (Genoa, Italy)

 
 

Transducer: 10 MHz, linear

 
 

Comments: Marked distension of the hip joint capsule. The large amount of the synovial fluid (*) allows a clear visualization of the insertion of the capsule. f = femur; a = acetabulum.

Diagnosis: Acute transient synovitis of the hip in a 9 years old patient

  
 

Equipment: AU4-Idea, Esaote Biomedica (Genoa, Italy)

 
 

Transducer: 10 MHz, linear

 
 

Comments: Marked joint cavity widening. This image has been obtained with high levels of power and gain: synovial fluid is fully anechoic (*), while articular cartilage of the femural head appears as a hypoechoic band between the sharp hyperechoic synovial fluid-cartilage interface (arrowheads) and bone-cartilage interface. f = femur.

Diagnosis: Acute transient synovitis of the hip in a 9 years old patient

  
 

Equipment: AU4-Idea, Esaote Biomedica (Genoa, Italy)

 
 

Transducer: 10 MHz, linear

 
 

Comments: Joint cavity widening, with evident signs of synovial proliferation (arrow). This image has been obtained with high levels of power and gain: synovial fluid is fully anechoic (*), while articular cartilage of the femural head appears as a hypoechoic band between the sharp hyperechoic synovial fluid-cartilage interface (arrowheads) and bone-cartilage interface. a = acetabulum; f = femur.
