The diagnosis of fat herniation should be considered in patients with positionally variable subcutaneous nodules,
especially in the lower extremities,
a rare condition occurred through weak points of fascia cruris crossed by perforating vessels that cause fascial defect.
Ultrasonographic examination is useful for detecting the fascial defect; in addition to offering high-resolution imaging,
ultrasound also provides the capability of real-time dynamic assessment of soft-tissue structures excluding other conditions caused by soft tissue tumours such as lipomas,
fibromas and the relatively common condition of muscle herniation.
A MRI exam,
performed by T1 weighted,
T2 weighted and T2 fat suppression sequences,
can be useful to confirm the ultrasound diagnosis.
