Hemophiliac bleed

Case contributed by Dr Jeremy Jones


Pain in the left groin following trivial trauma. History of haemophilia.

Patient Data

Age: 15 years
Gender: Male

Large intramuscular hematoma in the posteromedial left hip.


1 month later

There has been expansion of the previously demonstrated hematoma. Features remain appropriate for the diagnosis, especially since the patient has hemophilia and the onset of symptoms followed trauma and was acute.


3 months

The size of the lesion has decreased in size, but post-contrast there is peripheral enhancement and enhancement of edema (which is not uncommon).  Contrast had not previously been given.


9 months

Complete resolution of the left hip hematoma.

Case Discussion

The series of MRI examinations demonstrate an enlarging intramuscular hematoma that regresses completely within a year. Hematomas can have extremely aggressive imaging characteristics, especially when contrast is administered. Without an appropriate history, making a confident diagnosis may not be possible.
