Inguinal canal lipomas, also known as spermatic cord or round ligament lipomas, are a relatively common but often under-recognised finding on imaging.
Lipomas are usually asymptomatic but can sometimes cause pain and discomfort. They can present as a mass lesion.
They have no communication with the peritoneal fat. They are not considered as true tumours of fat but as extrusions of extraperitoneal fat extending into the inguinal canal.
Treatment and prognosis
They are a benign entity and no treatment is usually required in incidental asymptomatic cases. Resection can be offered patients who clinically symptomatic.
On imaging, possible differential considerations include:
- inguinal hernias containing fat
- other inguinal canal / spermatic cord masses 3
