A 36-year-old female has been on
long-term steroids for management of Crohn’s disease. She complains of pain
in her right groin radiating down the anteromedial thigh. She has an antalgic
gait and on examination of the hip there is decreased range of movement
especially flexion, abduction and internal rotation.
In this condition which of the
following statements is true?
An x-ray of the hip will show early changes
CT scan is useful to show early changes
Bone scanning is very sensitive and specific and should be used to
detect early changes
MRI is specific but not sensitive and hence not useful for early
CT scan is useful to rule out advanced disease if duration is not clear
