Intramuscular Haematoma of the Thigh Following Anticoagulation

Clinical History

A 39-year old man presented with an acute onset of tense swelling of the right lateral thigh region. The patient was on anticoagulation therapy, at the time of this occurrence, for a different condition.

Ultrasound of the thigh was requested to assess for haematoma or other collections.

Case Description

Ultrasound revealed an 8 cm heterogeneous non-vascular haematoma within the intramuscular layer of the right lateral thigh region.

Diagnosis/ Discussion/ Treatment/ Follow up

The patient had a CT angiogram of the lower limbs to assess the potential source of an acute bleed within the vessels. The ultrasound findings were confirmed on CT. However, there was no evidence of contrast extravasation to the pool of haematoma seen on CT.
