Dynamic ultrasound with postural change facilitated the detection of an incisional hernia in a case with negative MRI findings.

Incisional hernias commonly develop after abdominal surgeries with a lower incidence in patients receiving laparoscopy. Diagnosis through a non-surgical approach is usually made by computed tomography or magnetic resonance images (MRI) but both image modalities require patients to be examined in a supine position. We reported a case noticing a mass over her right lower abdomen after a laparoscopic liver segmentectomy with negative findings of hernia on MRI. A hernia sac was found by ultrasound with the patient being standing, highlighting the utility of dynamic ultrasound with postural change in investigation of incisional hernias.
