A Large Intramuscular Haematoma Coexisting with Lesser Trochanter Osteochondroma

Clinical History

A 35-year old man presented with a medial right thigh mass that he had felt for two weeks. An ultrasound was requested to assess the nature of the mass.

Case Description

Ultrasound was performed using linear and curvilinear transducers. This revealed a large area of intramuscular haematoma with some linear calcific component within the medial upper thigh compartment.

Diagnosis/ Discussion/ Treatment/ Follow up

A subsequent MRI revealed a sessile osteochondroma at the right lesser trochanter with no significant cartilage and an adjacent haemorrhagic fluid extending from the right ischiofemoral interval to the adductor compartment caudally.
