Sampson syndrome refers to a type of superficial endometriosis, where multiple superficial plaques may be seen scattered in the peritoneum and pelvic ligaments.
Clinical presentation
The patient may present with non-specific abdominal pain.
Radiographic features
At laparoscopy, they are typically described as 'powder-burn' or 'gun-shot' lesions. As the lesions are quite tiny and scattered, MRI or ultrasound scans are usually inconclusive for this kind of endometriosis. However, if >5 mm, they may be seen as small cystic areas appearing hyperintense on T1W and hypointense on T2W images (like hemorrhagic cyst).
