From: The tip of the iceberg: lipomatous tumours presenting as abdominal or pelvic wall hernias
Left panel: Coronal T1-weighted image of the pelvis and upper thigh: large low signal intensity mass is seen in the left iliopsoas compartment (red arrows). This demonstrates a paucity of fat signal. Middle panel: Coronal T1 TIRM image of the pelvis and upper thigh: a high signal intensity is seen in the tumour with low signal septations and an overall aggressive appearance. Right panel: AP X-ray of the pelvis: red arrow confirms an area of intra-lesional chondroid calcifications. Biopsy confirmed a high-grade chondrosarcoma. Intra-operatively the tumour appeared to be originating from the lesser trochanter
