I wonder if intra-articular contrast injection might have caused a capsular
tear at the shoulder.
45 year old patient imaged for chronic pain in her right shoulder with
decreased ROM. She described a ‘painful arc’ with severely restricted
abduction.
I injected 8 cc of gadolinium against moderate resistance, judging this
amount to be enough for this rather petite woman. She did not complain of
any pain after needle placement, although having injected some anaesthetic
first I wouldn’t have expected it anyway.
To me it seems there is a capsular defect with extraarticular contrast at
the axillar recess. Would you concur? Is it iatrogenic? Does it need to be
treated?
