CASE 304: HIP PAIN, Dr PHAN THANH HẢI, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

PLS DOWNLOAD THE LINK FOR PICTURES


Man 43 yo, one week ago, pain at  his left  hip  while moving his thigh, no trauma history.
Ultrasound first saw  the  left hip joint  having a small amout of fluid collection  and  more  Power Doppler in muscles  around the hip ( see 4 US images).





MSCT was done but radiologist said nothing abnormal detected.




MRI detected abnormal head of left  femur  bone  looked like  aseptic necrotic femoral head.




Please compare  diagnostic values of 3 diagnostic modalities for this case:ultrasound, MSCT and MRI.

DISCUSSION:
In this case  ultrasound first  saw abnormal edema in the left hip joint. CT  scanning  cannot  detected  at the early stage  of  head femoral AVN disease ( AVN, avascular necrosis). MRI  was the best  imaging modality for  diagnosing  AVN  in this case. Early  diagnosing  may cause  good response  to medical treatment.
