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.
